Within western political, media and academic discourses, Muslim communities are predominantly seen through the prism of their Islamic religiosities, yet there exist within diasporic communities unique and complex secularisms. Drawing on detailed interview and ethnographic material gathered in the UK, this book examines the ways in which a form of secularism ? ?non-Islamiosity? ? amongst members of the Iranian diaspora shapes ideas and practices of diasporic community and identity, as well as wider social relations.
