Imam-Al-Gazzali was one of the greatest philosophers, thinker and educationists. His philosophy of education had stress upon the development of personality in which one should know oneself. He wanted such type of education which would help a person to know himself and his relationship with his God and world. Therefore, education must contribute to the all-round development of each individual-mind and body, intelligence, sensitivity, aesthetic sense, personal responsibility and spiritual values. All human being must be enabled to develop independent critical thinking and form their own judgment. We find Al-Ghazzali forestalling Descartes method of doubt, Hume’s Skepticism, kant’s criticism of pure reason and the spiritual empiricism of some of the philosophers of religion of our own times. Al-Ghazzali has been referred to by some historians as the single most influential Muslim after the Islamic prophet Muhammad (Peace Be upon Him). Within Islamic civilization he is considered to be a Mujaddid or renewer of the faith, who, according to tradition, appears once every century to restore the faith of the community. His works were so highly acclaimed by his contemporaries that al-ghazaali was awarded the honorific title "Proof “of Islam” (Hujjat al-Islam). Thus Al-Gazzali even today stands in the front rank of educationists. He was one of the greatest philosophers similar to the Western philosophers like Socrates, Plato, Descartes, kant, hume and John Lock. He has advocated that revelation is essential to recognize the reality and that is granted to the Messengers of God only by Almighty Allah.
