Muḥammad Al-Ghazali was one of the most prominent and influential philosophers, theologians, jurists, and mystics of Sunni Islam.
Islamic tradition considers him to be a Mujaddid, a renewer of the faith who, according to the prophetic hadith, appears once every century to restore the faith of the ummah, the Islamic Community. His works were so highly acclaimed by his contemporaries that al-Ghazali was awarded the honorific title "Proof of Islam" (Hujjat al-Islam).
Al-Ghazali believed that the Islamic spiritual tradition had become moribund and that the spiritual sciences taught by the first generation of Muslims had been forgotten. That belief resulted in his writing over 70 books on science, Islamic reasoning and Sufism during his life.
