'A comprehensive and in-depth study about Salafism. Through the Jordanian paradigm, Joas Wagemakers' book goes as deep as possible in understanding the dynamics of 'Salafism' as a whole - its inner debates, its main theological and political issues, the histories of those who embody its main expression. It is a much-needed contribution to the understanding of a world-wide phenomenon, raising the issue of differences and commonalities between 'quietist' and 'jihadi' Salafism - and the possible crossovers between the two.' Bernard Rougier, Sorbonne Paris III University 'This is an excellent book. It is by far more than a history of quietist Salafism in Jordan. The first chapter is, in fact, the best introduction to Salafism to be found anywhere. This book confirms that Joas Wagemakers is by now the world's best expert on the topic. He covers all the aspects of Salafism and deepens our knowledge of the subject, not only by going into much greater detail [on] what Salafism is and its historical background ... [but] he is unsurpassed in analyzing the nuances between the different currents of Salafism, the quietists, the politicos and the jihadi-Salafis.' Roel Meijer, Radboud University Nijmegen 'Wagemakers is a sure guide through the labyrinth of Jordanian Salafi networks. This book provides a wealth of information and shows how events, both local and regional, have shaped the attitudes of quietist Salafis and their relationship to the state. Wagemakers adds depth and nuance to our understanding of Salafism in Jordan.' Henri Lauziere, Northwestern University, Illinois
