This book offers a comparative analysis of contemporary approaches to the sÄ«rah genre (biography of Prophet Muhammad). It explores the connection and juxtaposition of the sÄ«rah genre with Islamic systematic theology (kalÄ?m), particularly in the context of the emergence of Islamic modernism. It also highlights the inherent interconnectedness of the sÄ«rah and kalÄ?m disciplines. The book presents a careful study of Fethullah Gülen reading and interpretation of the sÄ«rah within the broader framework of modern debates, investigating his approach through the lens of the kalÄ?m discipline and the philosophy of sÄ«rah. The author argues that reading the sÄ«rah from the perspective of the kalÄ?m discipline, kalÄ?misation of sÄ«rah, is a novel response to modern debates around the life of Prophet Muhammad. KalÄ?misation of sÄ«rah together with the notion of sÄ«rah philosophy, represents a significant advancement in the field, providing new methodological and interpretative frameworks that are likely to define future trajectories of sÄ«rah writings. Gülen contributions are both ground-breaking and forward-looking, offering novel ways to engage with and understand the sÄ«rah for a contemporary audience. This book is an essential resource for scholars and researchers in Islamic studies, theology, philosophy of religion, religious movements, and literature.
