To what extent can concepts such as orthodoxy and heresy - originating from a different religious and cultural tradition - be applied in an Islamic context? This new Major Work synthesises the latest scholarship to address and answer this question. It explores the terminology on religious 'deviation' found in Islamic texts, and looks at specific debated issues that shed light on the implications of the theoretical discussions. The issue of sectarianism and its different aspects is also examined, as are different cases of accusations of religious deviation and the consequences. The set also details cases of accusations of apostasy and blasphemy both against God and against the Prophet.

Presents the first systematic and cross-cultural examination of ideas of orthodoxy and heresy in a group of major religious traditions.

A comparative history of heresy in Latin and Greek Christianity, Judaism, and Islam, spanning the fourth to the sixteenth century.

Between the eighth and eleventh centuries, many defining features of classical Sunni Islam began to take shape. Among these was the formation of medieval Sunnism around the belief in the unimpeachable orthodoxy of four eponymous founders and their schools of law. In this original study, Ahmad Khan explores the history and cultural memory of one of these eponymous founders, Abū Ḥanīfa. Showing how Abū Ḥanīfa evolved from being the object of intense religious exclusion to a pillar of Sunni orthodoxy, Khan examines the concepts of orthodoxy and heresy, and outlines their changing meanings over the course of four centuries. He demonstrates that orthodoxy and heresy were neither fixed theological categories, nor pious fictions, but instead were impacted by everything from law and politics, to society and culture. This book illuminates the significant yet often neglected transformations in Islamic social, political and religious thought during this vibrant period.

This book presents the first systematic and cross-cultural exploration of ideas of heresy, as well as orthodoxy, in a group of major religious traditions, including Neo-Confucianism, Sunni Islam, rabbinic Judaism, and early Christianity. It shows how authorities in all four of these traditions used common strategies to distinguish orthodox truth from heretical error. These same strategies often appear in modern ideological polemics and studies of deviance as well as in traditional religious controversies. The party that most effectively uses these strategies often gains a decisive advantage in the struggle among competing claimants to orthodoxy. The author also shows how orthodoxy depends on heresy. Without heresy, or at least ideas of heresy, orthodoxy could not establish or perpetuate itself. In fact, in all four traditions orthodoxy constructed itself by creating an inversion of the heretical other. By highlighting the common patterns in constructions of orthodoxy and heresy in four major religious traditions, this book also sets in relief subtler variations that give each tradition a special character. In this way this study strikes a balance between the universal and the particular: it illuminates a general pattern in world intellectual history, but also shows how the traditions that illustrate this pattern are distinctive.

One of the most far-reaching developments in the history of Islam was the rise of the four classical Sunni schools of law between the ninth and eleventh centuries CE. Consolidation of these schools went hand in hand with the establishment of jurists' dominance over religious discourse and social institutions. Orthodoxy came to be defined as the consensus (ijma') of the Sunni jurists. Devin Stewart argues that it is to the margins of the emerging system that investigators must look to understand its historical dynamics.
