Muhammad was a great Prophet and a teacher. The Quran proclaims that he was chosent by Almighty Allah as a mercy to all creation and excellent exemplar who possessed an exalted standard of character and the last and final Messenger to all humanking. He successfully taught and conveyed the Message of Allah to the people of Arabia and thereby transformed the pagans of the entire Arabian Penunsula into stauch believers in the unity of Allah within twenty three years of this own lifetime.
