The Prophet of Islam - His Biography : Dr. Hamidullah
In the annals of men, individuals have not been lacking who conspicuously devoted their lives to the socio-religious reform of their connected peoples. We find them in every epoch and in all lands. In India, there lived those who transmitted to the world the Vedas, and there was also the great Gautama Buddha; China had its Confucius; the Avesta was produced in Iran. Babylonia gave to the world one of the greatest reformers, the Prophet Abraham (not to speak of such of his ancestors as Enoch and Noah about whom we have very scanty information). The Jewish people may rightly be proud of a long series of reformers: Moses, Samuel, David, Solomon, and Jesus among others.
