Muhammad is the one among the prophets whose life is to be found in history. Born of the family of Ishmael, Muhammad had in him the prophetic heritage, and before him that purpose to be fulfilled which had been prophesied by Abraham in the Old Testament. The Prophet became an orphan in his childhood and knew what it is in the world to be without the tender care of the mother and without the protection of the father. This experience was the first preparation for the child who was born to sympathize in the pain of others.
