The volume contains editions of the extant parts of two hitherto unknown theological works by the _Būyid_ vizier al-Ṣāḥib b. ʿAbbād. The manuscripts on which the edition is based come from Cairo Geniza store rooms.

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.". (shrink)

Die Studien zur Geschichte und Kultur des islamischen Orients / Studies in the History and Culture of the Islamic Orient ist die Reihe der "Beihefte" zur Zeitschrift Der Islam. Beide werden von der Abteilung für Geschichte und Kultur des Vorderen Orients, Asien-Afrika-Institut, Universität Hamburg herausgegeben. Die Abteilung wurde im Jahre 1908 noch vor der Universität Hamburg gegründet. Sie war unter ihrem ersten Direktor C. H. Becker das erste wissenschaftliche Zentrum in Deutschland, in dem die Lehre und Forschung sich auf die (...) historischen und kulturwissenschaftlichen und nicht allein die philologischen Aspekte bei der Erforschung der islamischen Welt konzentrierte. Viele führende Experten der deutschen Islamwissenschaft haben hier gelehrt und/oder studiert. Mit dem gleichen hohen Anspruch und der gleichen hohen Qualität wie Der Islamhaben die "Beihefte" zahlreiche Arbeiten über die Geschichte und Kultur der islamischen Welt publiziert, die jeweils Meilensteine in ihrem Feld darstellten. Die seit 2004 erscheinende "Neue Folge" der Beihefte baut auf dieser Tradition auf und bietet eine Plattform für die Publikation von Studien über die Geschichte und Kultur der islamischen Welt vom Beginn des Islams bis in die heutige Zeit.

This volume presents three of the Epistles of the Brethren of Purity, a monumental work of medieval Islamic learning. Epistle 49 explores the hierarchy of existence; Epistle 50 describes the proper attitudes towards body and soul; Epistle 51 considers the arrangement of the world on numerical principles.

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 ShÄ«ism). The first sections contain articles examining intellectual and historical aspects of Mutazilism, the IbÄ á, iyya, á, ¤anafism and MÄ turidism, Sufism and Philosophy. The final group of articles focuses on aspects of early Muslim history. A detailed index completes the volume.

Muhammad al-Shahrastani, the famous Muslim theologian of the 12th century and author of the Book of Religious and Philosophical Sects, was greatly influenced by Ismaili teachings. In this work al-Shahrastani refutes the metaphysics of Ibn Sina (Avicenna) from an Ismaili point of view.
