I.B. Tauris in association with the Institute of Ismaili Studies The two sermons edited and translated here for the first time are primary material from the years before the establishment of the Fatimid caliphate in 297/909. The authors have been identified as Abu ‘Abd Allah al-Shi'i and Abu’l-‘Abbas Muhammad, two brothers who were central to the success of the Ismaili da'wa in North Africa. Da'wa, a term used to describe how Muslims teach others about the beliefs and practices of their Islamic faith, therefore provide a unique view of the nature and development of Islam throughout history. In this case, the primary texts shed light on the development of Islam among the Berbers of the Maghreb. The first text by Abu ‘Abd Allah al-Shi'i shows how the arguments for belief in the 'imamate' of the family of the Prophet, that is, the Shi'a belief that all imams should be spiritual descendants of the Prophet Muhammad and his household, were developed and presented to bring new adherents to the cause. The Book of the Keys to Grace by his elder brother Abu’l-‘Abbas, too, concerns not only the centrality of the imam in the faith but also sheds light on the hierarchy of the da’wa in this early period and its organisational sophistication. Both texts also reveal the contemporary theology propagated by the Ismaili da’wa, including for instance, the powerful analogy of Moses/Aaron and Muhammad/’Ali, the awareness of a variety of religious traditions and the use of detailed Qur’anic quotations and a wide range of hadith. As such they constitute primary source material of interest not only for Ismaili history but for this early period of Islam in general.

This personal memoir composed by a medieval scholar reveals an important discourse with two Ismaili leaders who spearheaded the Fatimid revolution in North Africa in 909-910. By reporting the thoughts and activities of Abu 'Abdallah al-Shi'i and his brother Abu'l-Abbas over a period of seven months, Ibn al-Haytham in his Kitab al-Munazarat (The Book of Discussions) provides an unparalleled insider's view to the foundations of the Fatimid state. As such, it is a unique document in the literature of early Islamic revolutionary movements as much as it represents one of the most valuable sources for the history of the medieval Muslim world.

The volume contains critical editions of the extant parts of two hitherto unknown theological works by the Buyid vizier al-Sahib b. 'Abbad (d. 385/925), who is well known to have vigorously promoted the teaching of Mu'tazili theology throughout Buyid territories and beyond. The manuscripts on which the edition is based come from Cairo Geniza store rooms. They consist of two manuscripts for each of the two texts-testimony to the impact of al-Sahib's education policy on the contemporaneous Jewish community in Cairo. The longer treatise of al-Sahib of ca. 350/960, possibly his Kitab Nahj al-sabil fi usul al-din, appears to be the earliest Mu'tazili work preserved among the Jewish community. The second, briefer treatise also contains a commentary by 'Abd al-Jabbar al-Hamadani (d. 415/1025).

This volume complements the selections of Wilferd Madelung's articles previously published by Variorum (Religious Schools and Sects in Medieval Islam, and Religious and Ethnic Movements in Medieval Islam). The first articles here examine legal and political aspects of early Shi`ism. The following studies relate to doctrinal views of the Zaydi imams al-Qasim b. Ibrahim al-Rassi and al-Natiq bi-l-Haqq and to Zaydi attitudes to Sufism. The final group focuses on the Isma`iliyya, their social and political history and aspects of their religious thought. A detailed index completes the volume.

Early Ibad i Theology presents the critical edition of six Arabic theological texts recently discovered in two manuscripts in Mzab in Algeria dating from the middle of the 8th century. The texts were sent by their author, the prominent Kufan Ibad i kalam theologian 'Abd Allah b. Yazid al-Fazari to North Africa where he had a large following in the Ibad i community later known as the Nukkar. They constitute the earliest extant body of Muslim kalam theology and are vital for the study of the initial development of rational theology in Islam. The sophisticated treatment of the divine attributes in these texts indicates that this subject developed considerably earlier in Islamic theology than previously accepted in modern scholarship.

This volume complements the selections of Wilferd Madelung's articles previously published by Variorum (Religious Schools and Sects in Medieval Islam, Religious and Ethnic Movements in Medieval Islam and Studies in Medieval ShAE"ism). The first sections contain articles examining intellectual and historical aspects of Mutazilism, the IbAE a iyya, aanafism and MAE turidism, Sufism and Philosophy. The final group of articles focuses on aspects of early Muslim history. A detailed index completes the volume.

This volume complements the selection of Wilferd Madelung's articles previously published by Variorum (Religious Schools and Sects in Medieval Islam), the earlier volume dealing principally with dogmatic issues, the present one concentrating on the political and social aspects. The first articles here examine the origins of the belief in the coming of the Mahdi and apocalyptic prophecies connected with this, such as arose among the Yemenite emigrants in Syria and Egypt. The following studies relate to Shi'ite and Alid movements under the Umayyad and Abbasid caliphates and to the political ideology of the Buyids. The final group focuses on the Yemen, its social structures and its historiography, in particular Zaydi sources. A section of additional notes and a detailed index complete the volume. Ce volume vient s'ajouter en complement de la collection d'articles de Wilferd Madelung prealablement publiee par Variorum (Religious Schools and Sects in Medieval Islam); le volume precedent traitant de questions de dogme et celui-ci se concentrant sur les aspects sociaux et politiques. Les premiers articles font l'examen des origines de la croyance en l'avenement du Mahdi et des prophecies apocalyptiques lui etant rattachees - telles celles qui ont vu le jour parmi les emigres yemenites en Syrie et en Egypte. Les etudes suivantes se rapportent aux mouvements chi'ite et alide sous les caliphats umayyade et abbaside, ainsi qu'A l'ideologie politique des Buyides. Un dernier groupe s'attache au Yemen, A ses structures sociales et son historiographie, en particulier aux sources Zaydi. Une section de notes supplementaires et index detaille viennent s'ajouter au recueil.

In Ibadi Texts from the 2nd/8th Century Abdulrahman Al-Salimi and Wilferd Madelung present an edition of fourteen Ibadi religious texts and explain their contents and extraordinary source value for the early history of Islam. The Ibadis constitutes the moderate wing of the Kharijite opposition movement to the Umayyad and 'Abbasid caliphates. The texts edited are mostly polemical letters to opponents or exhortatory to followers by 'Abd Allah b. Ibad , Abu l-'Ubayda Muslim b. Abi Karima and other Ibadi leaders in Basra, Oman and Hadramawt. An epistle detailing the offences of the caliph 'Uthman is by the early Kufan historiographer al-Haytham b. 'Adi. By their early date and independence of the mainstream historical tradition these txts offer the modern historian of Islam an invaluable complement to the well-known literary sources.

I.B.Tauris in association with the Institute of Ismaili Studies The Persian philosopher Ibn Sina (d. 1037), known in Europe as Avicenna, was arguably the greatest master of Aristotelian thought in the Muslim world. The symbolical Poem on the Soul (Qasidat al-nafs), which portrays all earthly human souls as in temporary exile from heaven, is traditionally attributed to Avicenna, and was received with enthusiasm by its commentators. A highly significant commentary on the Qasida was written by ?Ali b. Muhammad b. al-Walid (d. 1215 CE), a major early representative of the Tayyibi Ismaili tradition, which emerged and flourished in medieval Yemen. In his view, the poem encapsulated Tayyibi beliefs, whose doctrines bear striking parallels with late antique Gnosticism. Avicenna s Allegory on the Soul presents the first edition of the Arabic text of Ibn al-Walid s commentary, The Useful Epistle (al-Risala al-mufida), alongside an English translation and extended introduction. It offers invaluable insight into the intricacies of Muslim thought and a deeper understanding of Avicenna s substantial intellectual legacy."

In a comprehensive study of early Islamic history, Wilferd Madelung examines the conflict which developed after Muhammad's death for the leadership of the Muslim community. He pursues the history of this conflict through the reign of the four 'Rightly Guided' caliphs to its climax in the first inter-Muslim war. The outcome of the war, which marked the demise of the reign of the Early Companions, resulted in the lasting schism between Sunnite and Shi'ite Islam. Contrary to recent scholarly trends, the author brings out Ali's early claim to legitimate succession, which gained support from the Shi'a, and offers a convincing reinterpretation of early Islamic history. This book will make a major contribution to the debate over succession. Wilferd Madelung's book The Succession to Muhammad has been awarded the Best Book of the Year prize by the Islamic Republic of Iran for the year 1997.

In a convincing reinterpretation of early Islamic history, Wilferd Madelung examines the conflict that developed after the death of Muhammad for control of the Muslim community. He demonstrates how this conflict, which marked the demise of the first four caliphs, resulted in the lasting schism between Sunnite and Shi'ite Islam. In contrast to recent scholarly trends, the author takes up the Shi'i cause, arguing in defense of the succession of 'Ali. This book will make a major scholarly contribution to the debate over succession.
