This scholarly book presents a case study of some of the London-based work of a social movement known as Hizmet, or the Gulen Movement. This transnational faith-inspired movement represents a rising trend of philanthropic social activism around the world and increasingly now in the Muslim world. This book grew out of the author's deep interest in Muslims' interaction with modern society, their social activism, and their response and contributions to global transformation. The author provides a unique insight into the Hizmet Movement, how it draws on Islamic resources, how it should be classified, and how it differs from other social movements.
