Imam Ghazali Imam Muhammad Ghazali is one of the most celebrated scholars in Muslim history. One of the greatest jurists, theologians and mystics of the time, he is unanimously considered as the Reviver of Islam in the 5th century Hijri. He changed the course of early Islamic philosophy, shifting it away from the influence of Greek and Hellenistic philosophies. Imam Ghazali is credited with integrating Sufism into mainstream Islam. The Western medieval world knew him as Al-Gazel, the man who launched a devastating attack on contemporary philosophical thought. His most famous work “Ahya ul Uloom ud Din” (Revival of Religious Sciences) gained wide recognition in his time and remains relevant to this day.
