Born and died in Tus, in Khurasan (eastern province of Iran) between 1058 and 1111 CE, he was a Muslim theologian, jurist, philosopher, and mystic. Al-Imam al-Ghazali remains one of the most celebrated scholars in the history of Islamic thought. His thought had an important influence on both Muslim philosophers and Christian medieval philosophers. Margaret Smith writes in her book Al-Ghazali: The Mystic (London 1944): "There can be no doubt that Al-Ghazali's works would be among the first to attract the attention of these European scholars". She adds: "The greatest of these Christian writers who was influenced by Al-Ghazali was St. Thomas Aquinas (1225–1274), who made a study of the Arabic writers and admitted his indebtedness to them. He studied at the University of Naples where the influence of Arab literature and culture was predominant at the time."
