Al-Ghazali

Abu hamed Muhammad ibn Muhammad Al Ghazali (1058-1111) was a Persian Islamic philosopher, theologian, psychologist, and mystic, known today as one of the most famous Sunni scholars in history, sometimes cited as next-in-importance only to Muhammad. Born in Tus, Al-Ghazzali was a pioneer of methodic doubt; his work The Incoherence of Philosophers shifted early Islamic philosophy from metaphysics to the theory of occasionalism, an Islamic doctrine that states cause-and-effect is controlled by God. He also succeeded in bringing orthodox Islam in contact with Sufism. The author of more than 70 books on various subjects, his influence continues to stretch far and wide even today.
