A unique collection of studies, the present volume sheds new light on central themes of Ibn Taymiyya's (661/1263-728/1328) and Ibn Qayyim al-Jawziyya's (691/1292-751/1350) thought and the relevance of their ideas to diverse Muslim societies. Investigating their positions in Islamic theology, philosophy and law, the contributions discuss a wide range of subjects, e.g. law and order; the divine compulsion of human beings; the eternity of eschatological punishment; the treatment of Sufi terminology; and the proper Islamic attitude towards Christianity. Notably, a section of the book is dedicated to analyzing Ibn Taymiyya's struggle for and against reason as well as his image as a philosopher in contemporary Islamic thought. Several articles present the influential legacy of both thinkers in shaping an Islamic discourse facing the challenges of modernity. This volume will be especially useful for students and scholars of Islamic studies, philosophy, sociology, theology, and history of ideas.
