This collection of essays assesses various dimensions of dialogue between Islam and other religions, especially Christianity. This book celebrates the work of Professor Mahmoud Ayoub and reflects the themes that are central in his scholarship spanned over the last three decades and which are more relevant than ever at the inauguration of the twenty-first century. The themes reflected are the Qur’an and hadith, theology and philosophy, and Islam’s interaction with other religions. Ayoub needs no introduction to those familiar with and engaged in inter-religious dialogue in general and Muslim-Christian-Jewish dialogue in particular. He is a well-known Muslim scholar and historian of religion, currently director of the Islamic studies program in the department of religion at Temple University in Philadelphia. His broad area of interest is of course Islamic studies but he has also exerted considerable scholarly efforts in comparative religion. As evidenced from Dr. Ayoub’s works, he moves with ease between philosophy and mysticism, scripture and tradition and between Islam and other religions. As a Muslim, Ayoub has provided a model of being religious which combines openness to others without compromising rigorous historical scholarship. Contributors to this volume include some of his close friends and colleagues, as well as former students both Muslim and Christian. This book was previously published as a special issue of Islam and Christian-Muslim Relations.
