Quran 21:109 · Al-Anbya

All the prophets who were sent by God were sent here for one and the same purpose. Through them, God wanted to impart to man that knowledge of reality which would enable him to become an inhabitant of eternal paradise. But every time a prophet came, he was rejected. All prophets were dispensers of God’s grace on earth. But, what distinguished the Prophet Muhammad from the others was that God chose him as a means of sending a special kind of His blessings to His subjects. God decided that a door of guidance, which had hitherto been closed to them, should be opened forever. Accordingly, it was God’s plan that his addressees’ community should somehow be brought on to the right path, so that a strong band of his Companions could be formed, made up of stalwarts who could then bring about a revolution in the world and thus change the course of history. This gracious plan of God was indeed fulfilled, completely and perfectly, through the Prophet Muhammad and his Companions.
