The Ideology of ISIS and the Roots of Terrorism

In this groundbreaking study, Asaad Alsaleh reveals how ISIS weaponized Islamic texts to transform Islamic theology into a tool of ideological violence. Drawing on close readings of Arabic primary sources, he explores the historic notion of takfir - excommunication -- from the 'apostasy wars' that followed Prophet Muhammad's death through modern jihadist movements. Alsaleh demonstrates how political authorities systematically exploited excommunication to eliminate perceived threats throughout Muslim history. He also examines the theological mechanisms through which the group legitimizes violence. Combining theological, historical, and ideological analysis, Alsaleh argues that ISIS pursues a utopian project based on man-made ideology rather than divine revelation, thus distinguishing authentic Islam (rooted in the Qur'an and authenticated Prophetic hadith) from human interpretations that have been tragically conflated with the religion itself. Alsaleh concludes with suggestions as to how to solve the problems that ideology poses, emphasizing that clear efforts must be made to disentangle ideology from religion.
