Although a number of conferences have been organised in recent years emphasising the social, civic and educational activities of the Gulen Movement, as well as Gulen's contribution to inter-religious dialogue, very little attention has been paid to his formal and informal education, his scholarly works and his interpretation of basic Islamic sources and disciplines in the modern period. In fact, his expertise goes beyond the limitations of modern academic compartmentalisation of Islamic studies. Gulen's analyses have social, psychological, cultural and philosophical dimensions that differentiate his Qur'anic exegesis from that of his many classical counterparts. This edited book aims to explore Gulen's personal and theological profile in relation to Qur'anic exegesis (tafsir), Prophetic tradition (hadith), Islamic law (fiqh), Islamic systematic theology (kalam), Sufism (tasawwuf), and Muslim heresiography (al-milal wa al-nihal or firaq literatures).
