Muhammed is the one among the Prophets the account of whose life is to be found in history. Born of the family of Ishmael, Muhammed had in him the prophetic heritage, and, before him, that purpose to be fulfilled, the prophecy of which had been made by Abraham in the Old Testament. The Prophet became an orphan in his childhood, and had known what it is in the world to be without the tender care of the mother and without the protection of the father, when a child. And this experience was the first preparation for the child who was born to sympathize in the pain of others.
