A number of conferences have been organized in recent years emphasizing the social, civic, and educational activities of the Gülen Movement (aka Hizmet), as well as Gülen's contribution to interreligious dialogue. However, 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 compartmentalization of Islamic studies. This edited book aims to explore Fethullah Gülen's personal and theological profile in relation to Qur'anic exegesis (tafsir), Prophetic tradition (hadith), Islamic law (fiqh), Islamic systematic theology (kalam), and Islamic mysticism or Sufism (tasawwuf). Fethullah Gülen's private study circle and the texts and style of education that he continues to teach is also separately covered in order to reflect his mastership over Islamic disciplines.
