ENCYLOPEDIA MEDIEVAL ISLAMIC PART 12

IBN SHADDAD

Baha’ al-Din Abu’l-Mahasin Yusuf b. Rafi‘

  Baha’ al-Din Abu’l-Mahasin Yusuf b. Rafi‘, a leading scholar, writer, and official of the Jazira and Syria, wasn born in the northern Mesopotamian city of Mosul in AH 439/1145 CE. After a period in Baghdad as mu‘id (assistant teacher) at themadrasa(Islamic school), the celebrated Madrasa al-Nizamiyya, founded by the Seljuk vizier Nizam al-Mulk, he was made mudarris (professor) in one of his native city’s madrasas.

  During this period Baha’ al-Din was appointed by the Zankid rulers of Mosul to several diplomatic missions, including two embassies to Saladin. In AH 584/1188 CE, on his return home from the pilgrimage, he was received by Saladin, who was besieging the northern Syrian stronghold of  Krak des Chevaliers. The judicious presentation to the sultan by Baha’ al-Din of a treatise he had written, titled Fada’il al-Jihad (The Virtues of Holy War), resulted soon after in Baha’ al-Din’s appointment as Saladin’s qadi al-‘askar (Islamic judge of the army). He was later given judicial and administrative responsibilities in Jerusalem. Baha’ al-Din became a close companion and confidant of the sultan, remaining so until Saladin’s death at Damascus in AH 589/1193 CE. He then played an important part in negotiating the division of power among Saladin’s heirs.

  After two years in the service of Saladin’s eldest son al-Malik al-Afdal ‘Ali, ruler of Damascus, in AH 591/1195 CE, Baha’ al-Din moved to Aleppo. There he was appointedqadi(Islamic judge) of the city by its ruler, al-Malik al-Zahir Ghazi, who was another of Saladin’s sons. In AH 601/1204 CE, he founded his own religious school in Aleppo, the Madrasa alSahibiyya, adding to it adar al-hadith (school for the study of prophetic tradition). Linking the two foundations was a mausoleum that he prepared for himself.

  Meanwhile, Baha’ al-Din’s diplomatic skills proved useful to the ruler of Aleppo: He made several visits to Cairo on behalf of  al-Malik al-Zahir in an effort to resolve disputes among the Ayyubids. He continued to serve al-Zahir’s heir, al-Malik al-‘Aziz. In AH 629/1232 CE, he headed the delegation that went to Cairo to bring the daughter of the Ayyubid ruler of Egypt back to Aleppo to marry al-Malik al-‘Aziz. Baha’ al-Din died at Aleppo in AH 632/1235 CE, at nearly ninety years of age.

  Baha’ al-Din’s most important work is his biography of  Saladin, Sirat Salah al-Din, also called al-Nawadir al-sultaniyyah wa-l-mahasin al-Yusufiyyah (The Sultan’s Rare Qualities and the Excellences of Yusuf [that is, Saladin]). It combines elements of hagiography, propaganda, history, and autobiography. The first part of the work describes the sultan’s accomplishments and moral excellence. Throughout the work Saladin is presented as exhorting the Muslims not to slacken their efforts against the Crusaders. The second part of the book is an account of Saladin’s career from AH 558/1163 CE, when he accompanied his Uncle Shirkuh’s expedition to Egypt, until his death in AH 589/1193 CE. For events after the summer of AH 584/1188 CE, when Baha’ al-Din joined the service of the sultan, the narrative becomes the eyewitness account of someone in Saladin’s inner circle, and a commensurately valuable source for the events of the Third Crusade.

IBN SHAHIN, NISSIM BEN JACOB (C. 990–1062)

  Nissim was a Talmudic scholar of Qayrawan who studied under his father, Rabbi Jacob ben Nissim, and Rabbi Hushiel, an illustrious scholar of Italian origin. Nissim was supported financially by the famed poet and patron of Jewish learning, Samuel Ibn Naghrela. The latter composed a poem of consolation upon the death of  Nissim’s young and only son and married his son Joseph to Nissim’s daughter. Several works (some fragmentary) by Nissim survive in addition to commentaries on tracts of the Talmud and a compilation of legal rulings. Composed in JudeoArabic, his A Key to the Locks of the Talmudis a reference work of quotations found in the Talmud, and his Revelation of Mysteriesis a topical treatment of subjects such as biblical exegesis, religious polemics, respons, and explications of sections of the Talmud and Midrash. These works exhibit tendencies toward systemization and had profound effects on Jewish intellectuals in the Islamic and Christian domains. The Judeo-Arabic collection of rabbinic tales titled Kitab al-faraj ba‘d al-shidda (Book of Relief after Adversity) is addressed to console a relative called Dunash who had requested a book to relieve him following the death of a son. Dunash had mentioned that the ‘‘heretics’’ (that is, Muslims) possessed such a book on the subject of relief after adversity, possibly referring to al-Tanukhi’s Kitab al-faraj ba‘d al-shidda or a similar work. Al-Tanukhi’s work is anadabcollection on various species of relief (foretold in omens, realized through dreams, freedom from prison or execution, and so on) and aphorisms concerning relief from Qur’an, hadith, and poetry. Ibn Shahin’s book is an anthology of stories, mostly gleaned from rabbinic sources, that assures the reader of God’s justice (despite its mysteries) and discusses the qualities of scholars, virtuous and perfidious women, the wickedness of hypocrites, and the duty to pursue kindness and charity while abstaining from evil. The book also draws on apocryphal Jewish books (such asBen Sira)and,inall likelihood, stories from Islamic literature; the book bears some earmarks of Arabic storytelling techniques. It enjoyed great popularity in the medieval period (as testified by Geniza letters) and had direct influence on later Jewish works, such as Joseph Ibn Zabarah’s Book of  Delights and Moses de Leon’sZohar.

IBN SINA, OR AVICENNA

  Abu ‘Ali al-Hasan Ibn Sina (ca. 980–1037 CE), known in Latin as Avicenna, was a physician, natural philosopher, mathematician, poetic mystic, and princely minister. Of Persian descent, he was born in Afshana in the province of Bukhara. His philosophical chief work, Kitab al-shifa’ (Book of Healing), which was known in Latin asLiber Sufficientia, together with its condensed revision, Kitab al-najat (Book of Deliverance),led many to regard him as being the authoritative Neoplatonist integrator of the Aristotelian corpus. However, his intellectual acumen elevates his station beyond that of a commentator and lets him stand as an insightful thinker in his own right. His philosophical investigations covered mathematics, music, logic, physical and psychical sciences, as well as metaphysics and theology. In geometry, he critically examined Euclid’s Elementsand attempted to prove its fifth postulate. In his Aristotelian intromission conception of vision, he showed that the velocity of light had a finite magnitude. Partly influenced by Porphyry’sI sagoge, Aristotle’s Organon, and Galen’s logical investigations, he eventually developed intricate forms of propositional logic. Furthermore, he founded a prototheory of meaning that was partially embodied in his work Kitab al-hudud (Book of Definitions), wherein he arrived at definitions by way of a rigorous distinction among concepts while, unlike most Platonists, he celebrated the merits of the art of persuasion and rhetoric. In astronomy he endeavored to systematize his observations that were grounded by Ptolemy’s Almagest, and in mechanics he built on the theories of Heron of Alexandria while also seeking to improve the precision of instrumental readings. In his physical inquiries he studied different forms of energy, heat, and force, while presenting a more coherent account of the interconnection between time and motion than what is habitually associated with Aristotle’s Physics. One of his important achievements in natural philosophy is attested to in his account of the soul in Kitab al-nafs (Treatise on the Soul), which was preserved in his al-Shifaandal Najat, and was translated into Latin under the title De Anima. Therein, he presented an affirmation of the existence of the soul that rested on a radical mindbody dualism in an argument that is customarily referred to as ‘‘the flying person argument,’’ which anticipates Descartes’s ‘‘cogito ergo sum.’’ He also elucidated the notion of ‘‘intentionality’’ in the workings of the internal sense of the faculty of estimation (wahm) and its pragmatic entailments. Ranking among the most influential of metaphysicians in the history of philosophy, Ibn Sina offered an original elucidation of the question of ‘‘being’’ (al-wujud) that was mediated by a methodical distinction between essence and existence and oriented by an ontological consideration of the modalities of necessity, contingency, and impossibility. Taking the contingent to be a mere potentiality of being, whose existence or nonexistence did not entail a contradiction, Ibn Sina construed all creatures in actuality as being necessary existents due to something other than themselves.

  Consequently, any contingent had its essence distinct from its existence while being existentially dependent on causes that are external to it, which lead back to the One Necessary Existent due to Itself Whose Essence is none other than Its Existence. In this, Ibn Sina eschewed Aristotle’s reduction of ‘‘being’’ into the Greek conception of ousia (substance or essence), and he conceived the Deity as being the metaphysical First Cause of existence rather than being the physical Unmoved Cause of motion. Although his consideration of  Divine creation was primarily mediated by an attempt to found a synthesis between Aristotle’s naturalism and monotheistic creationism, his ontology remained more akin to Neoplatoni stemanationism, which took the One Necessary Existent to be the Source of all existential effusion. In this processional hierarchical participation in ‘‘being,’’ the Active Intellect played a necessary role in the genesis of human knowledge. Following Plato, Ibn Sina held that knowledge, which consisted of grasping the intelligible, did ultimately determine the fate of the rational soul in the hereafter. Believing that the universality of our ideas was attributed to the mind itself, he additionally held that our passive individual intellects are in a state of potency with regard to knowledge, unlike the Active impersonal and separate Intellect that is in a state of actual perennial thinking. Consequently, our passive intellect quamind acquires ideas by being in contact with the Active Intellect without compromising its own independent substantiality or immortality. In a mystical tone that becomes most pronounced in Kitab al-isharat wa-l-tanbihat (Book of Hints and Pointers), Ibn Sina also maintained that certain elect souls area pable of realizing a union with the Universal Active Intellect, thereby attaining the station of prophecy. His philosophical views were debated by Averroes and Maimonides, criticized by al-Ghazali, and integrated by intellectual authorities in medieval Europe, such as Thomas Aquinas, Duns Scotus, and Roger Bacon. His thinking also impacted the course of development of the ontotheological systems of prominent Muslim scholars such as Suhrawardi, Tusi, and Mulla Sadra. In all of this, his philosophical wisdom did not outshine his celebrated reputation as a physician, and his classic Kitab al-qanun fi’l-tibb (The Canon in Medicine), which was translated into Latin in the twelfth century CE (Liber Canonis), commanded an authority that almost surpassed that of Hippocrates and Galen and acted as the decisive compendium of the GrecoRoman-Arabic scientific medicine, and as the reference Materia Medica, throughout the medieval period and up to the Renaissance.

IBN TAGHRI BIRDI, ABU ‘L-MAHASIN YUSUF (C. 1410–1470 CE)

  Ibn Taghri Birdi was a historian of the Mamluk Sultanate of Egypt and Syria (1250–1517) known for his close ties to the Mamluk elite. His father, Taghri Birdi, was a mamluk amir(holder of military rank) who rose through the ranks during the reigns of the Mamluk sultans Barquq (r. 1382–1399) and Faraj (r. 1399–1412), achieving the position of  Viceroy in Damascus prior to his death in 1412. Ibn Taghri Birdi’s eldest sister was married to Faraj, and Ibn Taghri Birdi was a close companion of a son of sultan Jaqmaq (r. 1438–1453). Ibn Taghri Birdi received a grant of land revenues from Sultan al-Mu’ayyad Shaykh (r. 1412–1421) and accompanied Sultan Barsbay (r. 1422–1437) on a military campaign in Syria. He also knew Turkish quite well and was familiar with court life in Mamluk Cairo. These and other connections served him well during his career as religious stipendiary, scholar, and author.

  Ibn Taghri Birdi wrote several works, but he is best known today for his biographical dictionary and two historical chronicles. The dictionary, Al-Manhal al-Safi wa al-Mustawfi ba‘d al-Wafi,written in early adulthood, provides biographies of rulers, scholars, and amirs for the period 1248–1451, with scattered additions dating as late as 1458. His chronicle Al-Nujum al-Zahira fi Muluk Misr wa-al-Qahira surveys Egyptian history from the Muslim conquest in 641 up to 1468, although the sections post-1441 are mainly summaries taken from his second major chronicle, Al-Hawadith al-Duhur fi Mada al-Ayyam wa-al Shuhur, a detailed account of Mamluk history covering the period 1441–1469. Ibn Taghri Birdi considered this second work a continuation of al-Maqrizi’s important history, Kitab al-Suluk li-Ma‘rifat Duwal wa-al-Muluk.

  Ibn Taghri Birdi’s chronicles are focused on the elite segments of Mamluk-era society. As a walad al-nass (Arabic ‘‘son of the people,’’ meaning literally a son of those who mattered, that is, the Mamluks), it is perhaps not surprising that comparative studies of his work have indicated a tendency by Ibn Taghri Birdi to defend the actions and policies of the Mamluk rulers who were frequently criticized by other observers such as al-Maqrizi. That said, his work also contains frank and critical comments about specific officials both living and dead, for which it is possible that Ibn Taghri Birdi suffered both verbal and physical attacks.

IBN TAYMIYYA

  Taqi al-Din Ahmad Ibn Taymiyya (1263–1328) has been called both the most important figure from the Mamluk Sultanate of  Egypt and Syria (1250–1517) and the most significant Hanbali‘alimafter Ahmad b. Hanbal himself. The author of numerous fatawa and many longer works, he was also imprisoned by the Mamluk state six times for a cumulative period of more than six years between 1294 and 1328, including the last two years of his life.

  Ibn Taymiyya’s family moved to Damascus when he was a boy, fleeing from Mongol advances in upper Mesopotamia. Ibn Taymiyya was educated within the Hanbali madhhab and by 1284 was teaching in a major madrasa in Damascus. His subsequent career was marked by several brushes with state power, the rivalry and admiration of other jurists, and significant popularity among the Damascene population. His public life was marked by zealous devotion to the principals he held dear and the courage to face those whom his statements disturbed, even if that meant imprisonment. It has also been argued that his popularity with the populace disturbed the Mamluk rulers who found it threatening, and this may have contributed to his frequent imprisonment. His contemporary biographers, most of them also jurists, write of his personal piety, devotion to justice, and defiance of authority. There is a suggestion, however, particularly in the writings of al-Dhahabi (d. 1339), that Ibn Taymiyya had a difficult personality.

  Known first as a Hadith scholar, Ibn Taymiyya’s written output ranges far and wide. He wrote about and preached the importance of jihad against enemies of the Muslim world, in particular against the Mongols. (When Il-Khan Ghazan invaded Syria in1300, Ibn Taymiyya was a spokesperson of the resistance in Damascus.) He stressed the important example of the pious ancestors (al-salaf al-salih) and condemned what he saw as the excesses of some Sufi practices. In one of his major works, al-Siyasa al-Shar‘iyya, Ibn Taymiyya argued that since state and religion were inseparable, the temporal power and the revenues of the state must be harnessed to the path of God. A primary goal of the state was to ensure the centrality of the shari‘a, and this required the maintenance of order. Central to the state’s mission to maintain order was its ability to use coercive power to enforce the Qur’anic injunction ‘‘to command the good and forbid the wrong.’’

  After his death, Ibn Taymiyya’s ideas were further disseminated by his chief pupil Ibn Qayyim al-Jawziyya (d. 1350), an individual who also shared in some of his teacher’s punishment. Many of  Ibn Taymiyya’s ideas remain influential today, notably as refracted through the writings of the eighteenthcentury founder of Wahhabism, Muhammad b. ‘Abd al-Wahhab.

IBN TUFAYL

  Muhammad Ibn ‘Abd al-Malik Abu Bakr Ibn Tufayl was born in Guadix, not far from Granada, in 1110. Reputed for his learning in philosophy, jurisprudence, theology, and logic, as well as natural science, he gained the favor of the Almohad ruler, Abu Ya‘qub Yusuf, whom he served for many years as a political advisor and physician. Apart from his philosophical novel, Hayy Ibn Yaqzan (Living the Son of Awakened)—the only writing of his that has survived—Ibn Tufayl is known for the important role he played in presenting Averroes to Abu Ya‘qub as the person most capable of commenting on the works of Aristotle, this being a task Ibn Tufayl considered beyond his own reach. He died in Marrakesh in 1185.
 
  Ibn Tufayl focused on the relationship between the rational acquisition of knowledge and the path to it pursued by those who favor mysticism or Sufism in the philosophical introduction to Hayy Ibn Yaqzan. The work consists of three major parts. In the introduction, Ibn Tufayl explains his reasons for writing a book such as this and provides a general critique of philosophy, theology, and mysticism within the Arab world during his time. It is followed by the story of Hayy and by a formal conclusion in which Ibn Tufayl returns to the main theme of the work.

  As he explains in the introduction, the tale of  Hayy ibn Yaqzan comes as a response to a request from a friend that he unfold what he knows ‘‘of the secrets of the Oriental wisdom mentioned by the master, the chief, Abu ‘Ali Ibn Sina.’’ The question, he says, moved him to a strange state and caused him to discern a world beyond the present; it also caused him to discern the difficulty of speaking intelligently and circumspectly about this state. To prove the latter point, Ibn Tufayl passes in review what mystics and philosophers have said about it. Desirous of avoiding their foolishness, he speaks about the state only to the extent necessary, all the while pointing out the errors of his predecessors. He insists it is to be reached by ‘‘speculative knowledge’’ and ‘‘deliberative inquiry’’ and intimates that at least one philosopher—Ibn Bajja—reached that rank or perhaps even managed to go beyond it.

  Ibn Bajja did not describe this state in a book; nor has any other philosopher—either because they had no awareness of it or because it is too difficult to explain in a book. Ibn Tufayl dismisses as useless this task that has come down from Aristotle, Alfarabi, Avicenna, and all Andalusians prior to Ibn Bajja. Even Ibn Bajja, capable as he was of providing an account, failed to do so.

  To meet his friend’s request, Ibn Tufayl promises to expose the truth and knowledge he has learned from Alghazali and Avicenna, plus what he has gained from the philosophically inclined people of his time via study and reflection. Even so, he hesitates to give the results of what he has witnessed without also providing the principles, lest his interlocutor be content with a lower degree of insight. To arouse his interlocutor’s longing and encourage him to move along the path, Ibn Tufayl offers the tale of Hayy ibn Yaqzan. In other words, to leave us short of the end, it will indicate what the path is like.

  Hayy is either self-generated from a lump of clay or comes into being as do all humans but is then put into the sea in a basket because his mother, the sister of a very proud monarch, has wedded beneath her status in secret and fears for the fruit of this union should her brother learn of Hayy’s existence. However generated, Hayy grows up on a deserted island, nursed by a doe until he can fend for himself. During seven periods of seven years each, he discovers his natural surroundings and the way they interact, ascending by a series of inductions to embrace physics and its many divisions, as well as mathematics and its parts. He also gains insight into the nature of the heavenly bodies and into the character of the creator, as well as of his messenger and prophet, Muhammad s.a.w.

  Hayy’s education is all the more wondrous, for his enforced solitude deprives him of language. Only when he encounters Asal, the inhabitant of a neighboring island who is discontent with the way his fellow citizens practice religion, does Hayy learn to speak. They return to Asal’s island intent upon showing people the correct path, but they fail miserably. Only Salaman, a friend of Asal’s who discerns that most people cannot appreciate the truths Hayy wishes them to grasp and who is content to let them flounder, understands the limits of human reason. He is also too complacent for Hayy and Asal, not to mention most of Ibn Tufayl’s readers.

  The tale ends with Hayy and Asal deciding to return to the desert island to spend their remaining days meditating about divine matters. The people on the mainland are left without a solution to the problems that plague them, just as Ibn Tufayl’s interlocutor is left without a clear answer to his quest. We readers, having been enticed by this story, must now figure out for ourselves what it can possibly mean for us.

IBN TULUN

  Ibn Tulun, also Ahmad b. Tulun, was the founder of the Tulunid dynasty that ruled Egypt and Syria during the late ninth and early tenth centuries CE. Following the example of the Tahirids in Khurasan and the Aghlabids in North Africa, Ibn Tulun exploited his position in Egypt, establishing a semi autonomous state a secure distance from the ‘Abbasid capital in Baghdad while the caliphs battled rebellions and independence movements in the East.

  Ibn Tulun’s father, Tulun, entered the caliphate’s service as a Turkish slave, reportedly sent to the caliph al-Ma’mun from Bukhara. He formed part of  a large cadre of Turks who served in important military and administrative positions during his time. He eventually rose to become chief of al-Ma’mun’s personal guard.

  Ibn Tulun received training in military affairs and distinguished himself for his bravery. His widowed mother’s marriage to the Turkish general Bakbak gave him new opportunities for advancement. The caliph al-Mu‘tamid appointed Bakbak over Egypt in 868. Ibn Tulun became his stepfather’s lieutenant.

  Ibn Tulun increased his power through scheming, marriage, and fortuitous circumstances. He cultivated good relations with the caliph al-Mu‘tamid. After\ having the infamous controller of finances, Ibn alMudabbir, removed, he assumed primary responsibility for Egypt’s treasury, especially payments of tribute to Baghdad. When Ibn Tulun’s stepfather was assassinated, the new governor, Yarjukh, to whom he was related by marriage, kept him as lieutenant governor. The revolt of the governor of Palestine shortly afterward offered him a pretext to purchase military slaves, though he did not actually put down the revolt. These slaves were fiercely loyal to him and formed the core of  his army. He soon gained control of the financial administration of Syria, as well as Egypt.

  The appointment of the caliph’s son, Ja‘far, over Egypt and other Western provinces in 872 CE led to Ibn Tulun’s bid for autonomy. Ja‘far was a minor so Ibn Tulun exercised nearly independent authority.The caliph’s brother, al-Muwaffaq, who controlled the East and held most of the caliphate’s effective power, was preoccupied with repelling Turkish incursions and quelling independence movements. When Ibn Tulun failed to send a satisfactory sum of tribute, al-Muwaffaq dispatched an expedition to remove him. The expedition, however, returned without achieving its purpose. The ongoing rebellion of the Zanj in southern Iraq prevented al-Muwaffaq from ressing the matter further.

  Ibn Tulun consolidated his power in the years afterwards. He occupied Syria following al-Muwaffaq’s ailed expedition and led raids against the Byzantines in Anatolia. These raids enhanced his stature as a leader of holy war against the infidel. He later inscribed his name on his coinage, in addition to that of the Ja‘far. He never openly opposed the authority of the caliph. The prosperity of Egypt and Syria under his rule owes in part to his skill as an administrator. He showed restraint in his taxation. He kept, in addition, most revenues in these provinces rather than remitting them to Baghdad. Upon his death in 884, rule went to one of his sons, Khumarawayh.

IBN TUMART

  The founder of the al-Muwahhidun confederation, Abu Abdillah Muhammad b. Abdillah b. Tumart, a Masmudian Berber, was born (AH 471/1078 CE or AH 474/1081 CE) in the city of Sus, located in Morocco’s Anti-Atlas Mountains. We do not have much information about his youth. Observing negative developments such as moral and social decadence, the abandonment of religious principles, and the spread of the anthropomorphist conception of God under the al-Murabitun dynasty, Ibn Tumart was convinced of the necessity of social reform. He went to Cordoba to study theological sciences (499/ 1106). After taking lessons for about a year from Abu Abdillah Muhammed b. Ali b. Hamdin, Kadhi of Cordoba, he traveled to Mahdiya in Tunisia; there he participated in theological congregations of Abu Abdillah al-Mazeri. Studying with Ibn Abu Rendeka et-Turtushi in Alexandria, Kiyaˆ el-Herraˆs in Baghdad, Abu Bakir Muhammed b. Ahmed al-Shashi, and Mubarek b. Abdilcabbar, Ibn Tumart also read Imam Malik’s al-Muvatta’ with Abu Abdillah Muhammed b. Mansur al-Hadhrami. He traveled back to Maghreb from Alexandria in 510–511/1116. He also served his duty of pilgrimage to Mecca in this traveling period of eleven years. Traveling first to Bougie, and then to Beni Mallal, he met his first disciple and future successor Abdulmu’min al-Kumıˆ. His courageous personality caused him to be expelled from Vansharıˆs, Tlemcem, Shubat Enlil, and Fez; so he went to Marrakech, the capital of the al-Murabitun dynasty, but his activities there also caused him to be  expelled to Aghmat. He then went on to Tin Mal and continued his ‘‘common knowledge and forbid from denied’’(al-amr bi’l-ma‘ruˆf wa al-nahy an al-munkar) activities. Rejecting Ali b. Yusuf b. Tashfin’s invitation to return to Marrakech, he retreated to a cave, the Ghar al-muqaddas, and in Maghreb he began to spread the idea that Mahdi’s appearance was near (515/1121).

  That same year, his disciple Abdulmu’min and nine other men declared that Ibn Tumart was the Mahdi and that they would be loyal to him for all their lives. Ibn Tumart then started a violent rebellion in the command of Abdulmu’min el-Kumi ve Abu Muhammed al-Bashir against al-Murabitun, claiming that they supported an anthropomorphist conception of God, that they were unjust and causing the corruption of society, they had designs upon people’s lives and properties, and that they had thus given up the Islamic faith. There were many battles in the AntiAtlas region and the city of Sus for the next two years. Against al-Murabitun’s efforts to build up their strength, Ibn Tumart moved to Tin Mal to have a stronger defense (517/1123).

  Ibn Tumart began a large campaign in the command of Abu Muhammed al-Bashir to acquire Marrakech in 524 AH/1130. However, al-Muwahhidun could not gain hold of the city after a siege of six weeks and was defeated in the battle of Buhayra; five members of the council of ten were lost in this battle. Ibn Tumart passed away several months after this defeat in 14 Ramadhan 524/August 21, 1130. His successor, Abdulmu’min, and close friends concealed his death for about three years.

  His works include: (1) Kitabu Aazzi mayutlab (edited by Ignaz Goldziher) Algeria 1903 and Amm Ar U` Alibi (Algeria, 1985); (2) al-Murshida (published by Goldziher with a French translation (ZDMG,XLl, 72–73; XL1V, 168–170); (3) al-Aqide. In addition to the Egypt edition (Cairo, 1328), another edition is also available in French, translated by Henri Masse (Paris, 1928); (4) Muhazzi’l-Muwau`u`a’ (Hiza ˆnatu’l-Karawiyyin, no. 40/181; Rabat elHizaˆnetul-e`Amma, no. 840c, 1222c; published by Goldziher as Muwatta’u’l-Imaˆm al-Mahdıˆ (Algeria, 1905). (5) Mukhtasaru Sahihi Muslim (Ibn Yu ˆsuf Library, Marakesh, no. 403).

  Thinking himself a religious reformist, Ibn Tumart emphasized the notion of unity and doctrine of the imamate in his theory of faith. He defines knowledge, which he takes as the only basis for faith, as ‘‘the divine radiance in the heart which allows us to make a distinction between facts and qualities,’’ thus suggesting that only the qualities of objects and events can be known, not their essences. Because of Ibn Tumart’s emphasis on the unity of God, his followers were known as al-Muwahhidun (that is, Unitarians). God’s existence was known from intelligence; however, this knowledge was not innate, but deductive. Ibn Tumart ascribed some negative and demonstrative attributes to Allah. However, he gave intelligence no function in his definition of the relationship between the individual and his attributes. Therefore, his approach to this problem cannot be taken as the suspension of all attributes but a distinctive approach that avoided comparison and solidification. According to Ibn Tumart, predicative attributes in the dogmas must be believed, without trying to look for analogies.

  Ibn Tumart considered the imamate as a religious obligation and maintained that Imam was innocent (mae`sum), therefore, we can assert that Ibn Tumart was influenced by Shi‘i doctrine. However, he considered only the first three caliphs as legitimate Imams. Ibn Tumart received the acknowledgment of fealty through his disciples, who acknowledged him as the Mahdi, and he named only those who obeyed him as al-Muwahhidun; all others were regarded as infidels. He accepted the idea that the only creator is Allah and believed that the power of acting in a good or bad way was given by Allah to mankind; thus empowerment is the act in the place of the power of the human being.

  According to Ibn Tumart, all canonical judgements originated only from the Qur’an and Sunnah, all convictions and conventions reached by syllogisms were not primary, but supplementary; intelligence had no law-making authority. Ibn Tumart accepted ideas of several religious sects on some matters: He was more like an Ash‘ari in subjects concerning faith, a Maliki in subjects of fiqh, and also followed Ibn Hazm’s zahiri-salafi thought on some matters. However, the movement initiated by him can be regarded as a political movement to put an end to Al-Murabit’s confederation more than being a movement of religion and faith.

IBN WASIL, MUHAMMAD B. SALIM JAMAL AL-DIN

  Ibn Wasil (1208–1298) was a Syrian scholar most renowned for his chronicle Mufarrij al-kurub fi akhbar bani Ayyub (The Dissipater of Anxieties on the Reports of the Ayyubids), which covers, in detail, historical events of the twelfth and the first half of the thirteenth century. This work has drawn modern interest because it presents succinctly the main Crusading campaigns from a Middle Eastern point of view. Although Ibn Wasil relied on an array of earlier sources for the earlier parts of his work, some of which has been lost since then, he based his account  of thirteenth-century events (such as the Crusade of Louis IX, King of France, to Egypt in 1249–1250) on eyewitnesses or his own experiences.

  Ibn Wasil was well placed to observe the political developments and military events in the Middle East during his lifetime, as he was widely traveled and closely linked to the ruling echelons of society. Originating from Hama in northern Syria, he visited or dwelled in the main urban centers such as Baghdad, Cairo, and Damascus. Although descending from a family of relatively low prominence, he forged close relationships with prominent administrators and military commanders, as well as with Ayyubid and Mamluk rulers. In his sixties he returned to his hometown, where he led a low-profile life as the town’s chief judge.

  His educational and professional specialization was law, but no writings of his in this field are traceable. Rather, his extant oeuvre focuses on history, poetry, logic, and astronomy, all of which were of profit to him at various courts. For example, in 1261, while staying in southern Italy at the court of Manfred, the Staufer ruler of Sicily and son of Frederick II, as ambassador of the Mamluk ruler Baybars I, his knowledge of logic gained him the ruler’s praise. It is the immersion into these fields of knowledge that allowed him throughout his life close contacts with non-Muslim scholars. Consequently, one finds in his aforementioned chronicle passages where he discusses, for example, the conflict between the emperor and the papacy in thirteenth-century Europe, which is rarely found in other medieval chronicles by Muslim authors.

  Ibn Wasil’s chronicle did not enjoy wider popularity in the following centuries and was only ‘‘rediscovered’’ in the late nineteenth century with the rising interest in Crusading history.

IBN YUNUS, ‘ALI IBN ‘ABD AL-RAHMAN, D. FUSTAT, EGYPT

  Ibn Yu ˆnus was the leading astronomer of medieval Egypt and perhaps the most important of the entire Muslim world. He was a careful observer, a highly competent mathematician and calculator, and proposed much that was original. He was also the principal initiator of a tradition of astronomical timekeeping (‘ilm al-mıqat) in Islamic society, which is of prime importance because it included the regulation of the times of prayer. He compiled a monumental zıˆj, or astronomical handbook with tables, some four times the size of that of his predecessor al-Battanı (q.v.). This was called al-Zıˆj al-Hakimı because it was dedicated to the Fatimid ruler al-Hakim (q.v.). One of its most remarkable features is a record of more than one hundred observations of planetary conjunctions and solar and lunar eclipses, made by his predecessors in ninth- and tenth-century Baghdad and by himself. His solar, lunar, and planetary tables were much appreciated in later Egypt and the Yemen, but some of them were also adopted in a modified form in Iran. It was Ibn Yunus who compiled the first batch of the tables for timekeeping by the sun and regulating the times of Muslim prayer that later became part of the Cairo corpus of nearly two hundred pages of tables. These tables were used there until the nineteenth century. The medieval tables of this kind for such centers of astronomical activity as Damascus, Jerusalem, Aleppo, Istanbul, Tunis, and Taiz were inspired by the Cairo corpus.

IBN ZUR‘A, ABU ‘ALI ‘ISA ISHAQ

  The philosopher Ibn Zur‘a (AH 331–398/943–1008 CE) was born and died in Baghdad. Shortly after his death, the dominance of the Baghdad school of philosophy, with its close adherence to the Platonizing commentary tradition and involvement in translation, yielded to other centers of power and learning. Typical for the Baghdad school, Ibn Zur‘a was a Jacobite (Syrian Orthodox) Christian who associated on equal terms with Muslim and Jewish intellectuals.

  Ibn Zur‘a’s character and way of life can be seen from three viewpoints. Most significantly, there are contemporary references in his eight short treatises of Christian apologetics. Second, Ibn Zur‘a was known to the writer Abu Hayyan at-Tawhidi, whose books record discussions that took place, often under the patronage of powerful Buyid viziers. Finally, the medical biographer  Ibn Abi Usaybi‘a gives ‘‘case notes’’ regarding the treatment of  Ibn Zur‘a’s last illness, including mention of aspects of the philospher’s apparently stressful lifestyle.

  Ibn Zur‘a earned his living as a merchant, and traded with Byzantium. As a philosopher he was the devoted pupil and close friend of the leading logician Yahya ibn ‘Adi (d. 974 CE). The Ibn ‘Adi circle, including Ibn al-Khammar, Ibn al-Samh, Miskawayh, and ‘Isa ibn ‘Ali, attended the salons(majalis)of the vizier and patron Ibn Sa‘dan. Abu Hayyan was also there, although he was scornful of Ibn Zur‘a’s ‘‘vaunting of Aristotle, Plato, Socrates and Hippocrates.’’

  We know from bibliographies, such as those of  Ibn Zur‘a’s associate Ibn an-Nadim, of works such as On the Intellect, On the Reason for the Luminosity of the Planets,and On the Immortality of the Soul. These did not survive, although a shortDefense of Logicians and Philosophers against the Charge of  Irreligionis known. To later generations of Arab philosophers, Ibn Zur‘a was probably best known as a translator. Ibn Sina (Avicenna) used Ibn Zur‘a’s translation of Aristotle’s Sophistici elenchi, and Ibn Rushd may have used his translation of the Compendia of  Nicolaus of  Damascus. Among other translations, it is notable that part of a lost commentary by John Philoponus on Galen’s On the Uses of the Parts of the Bodyappears to survive in Ibn Zur‘a’s version. Ibn Zur‘a translated from Syriac into Arabic, and he probably did not know Greek. The importance of Syriac in the transmission of Greek philosophy to the Arabs is well known. Ibn Zur‘a played a role in making philosophy available to a wider audience, which demanded introductions and translations in idiomatic Arabic. Some of Ibn Zur‘a’s introductions to Aristotle’s logic have been published.

  In 979 CE, Ibn Zur‘a saw his late teacher, Yahya ibn ‘Adi, in a dream commanding him to write a treatise solving a problem with Ibn ‘Adi’s definition of God the Father as intellect (‘aql).Ibn Zur‘a was then asked to write an account of this vision by an unnamed ‘‘lord and brother.’’ This work, On the Composite Intellect,is the earliest of his dated treatises of Christian apologetics, which were generally not written for philosophers but at the request of a friend or in response to an opponent. At least twice the request for treatises came from Muslim friends, and often, addressees were high-ranking. One treatise is a refutation of the rationalist theologian (mutakallim) Abu ’l-Qasim al-Balkhi. The letter to Bishr ibn Finhas, written to a Jewish friend, is typical of the way Ibn Zur‘a combines rationalistic arguments with references to contemporary debates in these apologetic treatises. The work begins by setting out three different categories of law before concluding that the Mosaic law has been superseded. Then Ibn Zur‘a describes Plato’s tripartite division of the soul and argues that only Christianity teaches the virtues of the rational faculty to the highest degree. Ibn Zur‘a sets out the definition of the Trinity as Intellect, Active Intellect, and the Intellected (‘aql, ‘aqil, ma‘qul),which he learned from Ibn ‘Adi. In addition to such arguments, Ibn Zur‘a includes a discussion of proof texts, referring in passing to a group of Jews who expected the Messiah in 970–971 CE. At the end of the treatise Ibn Zur‘a gives an account of two problems concerning the resurrection, which he discussed with Jews.

  The account we have of Ibn Zur‘a’s death is tragic. One of the physicians who treated him relates that business opponents from the Syriac community ‘‘took him many times to the ruler, money was confiscated, and he was overtaken by many disasters.’’ The physician adds that other reasons for Ibn Zur‘a’s collapse were his hot temperament, and the pressure of writing a treatise on the immortality of the soul.

IDRISI

  Abu ‘Abd Allah Muhammad ibn Muhammad ibn ‘Abd Allah ibn Idris al-‘Ala bi-Amr Allah (ca. AH 493–560/1100–1165 CE) was the greatest medieval geographer. As a descendant of the Prophet Muhammad, this Muslim Arab scholar was titled al-Sharif al-Idrisi, but in the West he was known for a long time as Geographus Nubiensis, the Nubian Geographer. Born in Morocco and educated in Cordoba, he worked in Palermo at the court of the Norman king Roger II. The most important book he produced is a world geography in 1154, Nuzhat al-mushtaq fi ikhtiraq al-afaq (Entertainment for One Desiring to Travel Far); it is also called Kitab Rujjar (Book of Roger).He later wrote a shorter geography, known under a variety of Arabic titles and usually referred to as ‘‘The Little Idrisi.’’ Both are extensively illustrated with maps; the maps in Nuzhat al-mushtaq are oriented to the South, the maps in the latter book are smaller and often oriented to the east.

  Al-Idrisi traveled in Asia Minor, Europe, and North Africa, and in Sicily he was able to consult both European and Islamic sources procured from books and travel reports. Thus his Geography is a synthesis of information and cartographic traditions from both Islamic and European cultures; it is unsurpassed in narrative geography and maps of the Middle Ages. Because the work is a compilation and the data occasionally anachronistic, al-Idrisi’s work sometimes has been judged unoriginal. However, he introduced a new type of map that strongly impacted later cosmographers and thinkers, such as Ibn Khaldun, and used a projection that remains unexplained. Al-Idrisi produced more regional maps of the world than any other medieval cartographer, and his description of certain regions, such as the Balkans or northern Europe, is remarkably precise. The parts dealing with Africa remained an important source for Islamic and European cosmographers into the seventeenth century. Al-Idrisi’s distinctive cartography and narrative method make it possible to identify later imitations as works in ‘‘The Idrisi School.’’ Medieval European Mediterranean cartographers may have had some knowledge of his maps. The book Nuzhat al-mushtaq became the first secular Arabic work printed in Europe (Rome, 1592); a Latin translation was published in Paris in 1619.

  Al-Idrisi credited his patron Roger with the construction of a large world map, but the work was done by al-Idrisi. The text is a detailed description of the map, engraved on a silver disk and based on the Arabic version of  Marinus’s map reportedly created under the caliph al-Ma’mun (813–833). The silver prototype was lost, but the book contains a round, schematic map of the world and seventy rectangular maps of the seventy parts into which al-Idrisi had divided the world. Ten manuscripts of Nuzhat al-mushtaqsurvive, eight of them with maps; there is no complete good translation.

  The system developed by al-Idrisi used the Ptolemaic foundation adopted by the early Islamic scholars, whereby the round earth is divided into quarters and only the Inhabited Quarter is described. It is astronomically divided into seven latitudinal belts (‘‘climates’’), leaving off the extreme north and equatorial south. Although familiar with coordinates, alIdrisi did not use them; in addition to the parallel boundaries of the climates, he introduced, instead of meridians, ten longitudinal divisions. Thus the map and the narrative became divided into seventy sections. The numbering of climates is from south to north, the numbers of sections go west to east, again showing Greek influence. The text follows this arrangement after a brief general introduction, describing important geographical features of each section: cities, mountains, rivers, seas, islands, and so on, progressing eastward. Al-Idrisi names the most toponyms since Ptolemy, expanding and updating the medieval Arabic geographical inventory. He is academically unbiased, and all locations get more or less equal attention; he describes many identifiable locations for the first time in the geographical literature. Only ten of al-Idrisi’s sources are named, and contemporary information gets indis criminately mixed with data compiled from the Greek, Latin, and earlier Islamic sources.

  The narrative follows itineraries, connected by travel distances expressed in miles (mil), units (farsakh) (three miles), caravan stages (marhala),day marches, or days of sailing. The earth is depicted as surrounded by the Encircling Sea, al-Bahr al-Muhit (the Greek Ocean). Africa is extended eastward to form the southern coast of the Indian ocean, which, however, remains open in the Far East. The southern limit of the inhabited world is north of the equator in Nuzhat al-mushtaq, but south of the equator in The Little Idrisi. The southern portion of the round world map is filled with the African landmass, not shown on sectional maps. The western limit is the prime meridian drawn through the westernmost part of Africa, but the Fortunate Isles in the Atlantic are included. The easternmost country is Sila (Korea), supposedly at 180 E. The northern limit is at the Polar Circle (64 N.). The color-coded maps demonstrate a thoughtful and somewhat artistic approach, but neither the degrees nor itineraries are drawn on them, and their practical value is doubtful. A pieced-together Latin version of this map was produced in Paris by Petrus Bertius in the 1620s.

IDRISIDS

  The Idrisids, a local dynasty of Arab origin, emerged out of the shifting Berber tribal groupings of Islamic northwestern Africa (al-Maghrib) in the late eighth century CE. Surviving, often tenuously for some two centuries, the dynasty is notable for having founded the city of Fez (Fas), which was their capital, and for establishing Arabo-Islamic religious and political culture in this area.

  In 789, the leader of a powerful Berber tribal group, the Awraba, determined to politically and religiously legitimize his dominion, invited a localsharif, Idris ibn ‘Abd Allah, a descendant of ‘Ali b. Abu Talib, to serve as the regime’simam, or spiritual leader. After imam Idris was assassinated in 791, a period of political unrest followed, after which one of his young sons was namedimam as Idris II (808– 828). Idris II gained the political initiative from his Berber sponsors in 809 by founding a new capital city, Fez, and inviting Arabs from al-Andalus and the Aghlabid territories to settle there. Fez soon became the capital of the most powerful and dynamic state in the Maghrib, Idrisid power having expanded to include most of modern Morocco. Idris II was succeeded by his brother Muhammad (828–836), who passed the throne on to his son ‘Ali (836–859), who was then followed by his brother Yahya (859– 863). This was the period of greatest stability for the Idrisids, and Fez continued to be a favored destination of refugees and immigrants from al-Andalus and Ifriqiyya.

  The reign of the weak Yahya II (863–866) ushered in the decline of the dynasty, which was beset by internal rivalries and degenerated into a state of civil war. This was aggravated in the early tenth century by the rise of the Fatimids, who made them tributaries in 917. Eventually expelled from their capital by Miknasa Berbers, the Idrisids were driven into an alliance with the Umayyads of Cordoba, who allowed the dynasty to reconstitute itself, this time in the ROf mountains in the 930s, where their capital was the fortress of Hajar al-Nasr. For the following half century the Idrisids survived in semiautonomy by playing off the Umayyads and Fatimids, all the while beset by a host of tribal enemies. Following a defeat of the Umayyads in 958, the family recognized the authority of the Fatimids. In 972, the Umayyads rallied, defeated the Fatimid forces, and took members of the Idrisid family as prisoners to Cordoba, formally deposing al-Hasan b. al-Qasim Gannun in 974. Eventually al-Hasan made his way to Egypt and was reinstalled by the Fatimids in 985. That same year, al-Mansur, ruler of Umayyad al-Andalus, dispatched an army to depose al-Hasan, who was taken prisoner and executed.

  Fez is the Idrisid’s greatest legacy. The two great mosques, al-Qarawiyyin and al-Andalusiyyin, founded by refugees from Tunisia and al-Andalus, became centers of a vibrant religious culture, further stimulated by the dynasty’s connection to the family of ‘Ali. The city remained the cultural capital of the Maghrib until the dawn of the colonial period.
