‘Chris Chaplin’s carefully argued and sophisticated analysis of Salafism in Indonesia not only shows its appeal as a mix of social movement and individualizing force; it leverages rich ethnographic detail to reveal Salafism’s internal tensions and paradoxes as a defining trait, a necessary condition for the movement’s growth as it continues to inspire an increasingly conservative and politicized religious landscape. Relevant well beyond the Indonesian context, this book is an important contribution to the study of Islam. It will be widely read.’
