This book comparatively examines modern approaches towards the sīrah genre (biography of Prophet Muhammad). It explores the connection and juxtaposition of the sīrah genre with the Islamic systematic theology (kalām), particularly since the emergence of Islamic modernism. It sheds light on the interconnectedness of the sīrah and kalām disciplines as scholarship on sīrah and prophethood is inherently relevant. The book presents a careful study of the reading and interpretation of the sīrah genre as penned by Fethullah Gülen from a broad perspective of modern debates and investigates Gülen’s approach to sīrah based on kalām discipline and philosophy of sīrah. The author argues that reading sīrah from the perspective of the kalām discipline (kalāmisation of sīrah) is a novel response to modern debates around the life of Prophet Muhammad. Kalāmisation of sīrah together with the notion of sīrah philosophy is a significant contribution to sīrah writings in terms of methodology and approach and it is likely to define future trajectories of sīrah writings. Gülen’s contribution is ground-breaking and innovative, paving the way for new perspectives to read and interpret sīrah in a modern world for a contemporary audience. This book is of interest to scholars and researchers of Islamic studies, religion, religious movements, philosophy of religion, theology and literature.
