This insightful work by Holger M. Zellentin delves into the profound thesis that the Quran offers a unique perspective on the reformation of both Judaism and Christianity. Zellentin meticulously examines how the Quran, rather than being a standalone religious text, positions itself as a corrective and a return to the foundational principles shared by the Abrahamic faiths. The book argues that by understanding the Quran's narrative, readers can gain a deeper appreciation for its call to reform and its vision for restoring the original, uncorrupted essence of these ancient traditions. It challenges conventional views, inviting a fresh look at interfaith dialogue through the lens of shared historical and theological origins.
