Sufism has long constituted one of the most powerful drawcards to people embracing Islam. This book considers a broad range of questions relating to Sufism, including its history, manifestations in various countries and communities, its expression in poetry, women and Sufism, and expressions among popular spirituality. In addition, the volume challenges the long-held view of Sufism as being necessarily peaceful, through a consideration in one paper of Sufis engaging in violent Jihad. The book works at the interface between the scholarly and the practical, using rigorous methodology to ensure that its findings are reliable, while also giving attention to how Sufi thinking impacts the daily lives of Sufis. This represents an original and important dimension of this study, given the significant role played by Sufis throughout Islamic history in enriching discussion of intellectual and charismatic questions, as well as informing popular practice among “Folk” Muslims.
