Al-Mu'ayyad bi-llah al-Haruni (d. 411/1020) was a representative of the intellectual center of the Zaydiyya in Northern Iran and a student of the leading Muʿtazilite theologians of the time. In his Kitab Ithbat nubuwwat al-nabi he presents a proof of prophecy of Muḥammad and a refutation of the Isma'ilyya.The present volume explores the historical and intellectual context of the oeuvre and includes a partial critical edition of the text.

When debating the need for prophets, Muslim theologians frequently cited an objection from a group called the Barāhima – either a prophet conveys what is in accordance with reason, so they would be superfluous, or a prophet conveys what is contrary to reason, so they would be rejected. The Barāhima did not recognise prophecy or revelation, because they claimed that reason alone could guide them on the right path. But who were these Barāhima exactly? Were they Brahmans, as their title would suggest? And how did they become associated with this highly incisive objection to prophecy? This book traces the genealogy of the Barāhima and explores their profound impact on the evolution of Islamic theology. It also charts the pivotal role that the Kitāb al-Zumurrud played in disseminating the Barāhima’s critiques and in facilitating an epistemological turn in the wider discourse on prophecy (nubuwwa). When faced with the Barāhima, theologians were not only pressed to explain why rational agents required the input of revelation, but to also identify an epistemic gap that only a prophet could fill. A debate about whether humans required prophets thus evolved into a debate about what humans could and could not know by their own means.

The political thought of Muslim societies is all too often defined in religious terms, in which the writings of clerics are seen as representative and ideas about governance are treated as an extension of commentary on sacred texts. Disenchanting the Caliphate offers a groundbreaking new account of political discourse in Islamic history by examining Abbasid imperial practice, illuminating the emergence and influence of a vibrant secular tradition. Closely reading key eighth-century texts, Hayrettin Yücesoy argues that the ulema’s discourse of religious governance and the political thought of lay intellectuals diverged during this foundational period, with enduring consequences. He traces how notions of good governance and reflections on prudent statecraft arose among cosmopolitan literati who envisioned governing as an art. Competent in nonreligious branches of knowledge and trained in administrative professions, these belletrists articulated and defended secular political practices, reimagining the caliphal realm as politically constituted rather than natural. They sought to improve administrative efficiency and bolster state control for an empire made up of diverse cultures. Their ideas about moral cultivation, temporal reasoning, and governmental rationality endured for centuries as a counterpoint to religious rulership. Drawing on this history, Yücesoy critiques the concept of “Islamic political thought,” calling for decolonizing debates about “secular” and “religious” politics. Theoretically rich and historically grounded, Disenchanting the Caliphate is an insightful and provocative reconsideration of key strands of political discourse in the intellectual history of Muslim societies.

How widespread was authorship among rulers in the premodern Islamic world? The writings of different types of rulers in different regions and periods are analyzed in this book, from the early centuries in the central lands of Islam to 19th century Sudan. The composition of poetry appears as the most fertile area for authorship among rulers. Prose writings show a wide variety, from astrology to bookmaking, from autobiography to creeds. Some of the rulers made claims to special knowledge, but in all cases authorship played a special role in the construction of the rulers' authority and legitimacy.

In this examination of an extraordinary Islamic anti-Christian polemic, the author describes Q 'Abd al-Jabb?r's life, his intellectual heritage and the sectarian controversy of his day. Thus the reader will discover how, and why, a Muslim theologian reinterpreted Christian scripture, history and practice to develop an Islamic doctrine of Christianity.

In 385 AH/AD 995 the Qāḍī ‘Abd al-Jabbār, well known for his Mu‘tazilī theological writings, wrote the Confirmation of the Proofs of Prophecy, a work that includes a creative polemic against Christianity. ‘Abd al-Jabbār reinterprets the Bible, Church history (especially the lives of Paul and Constantine) and Christian practice to argue that Christians changed the Islamic religion of Jesus. The present work begins with an examination of the controversial theory that this polemic was borrowed from an unkown Judaeo-Christian group. The author argues that ‘Abd al-Jabbār's polemic is better understood as a response to his particular milieu and the on-going inter-religious debates of the medieval Islamic world. By examining the life and thought of ‘Abd al-Jabbār, along with the Islamic, Christian and Jewish antecedants to his polemic, the author uncovers the intimate relationship between sectarian controversy and the development of an Islamic doctrine on Christianity.
