Before he was six years old his mother died, and the doubly orphaned Muhammad was put under the charge of his grandfather Abdul Muttalib who took tender care of him. But the old chief died two years afterwards. On his deathbed he confided to his son Abu Talib the charge of the little orphan.
When Muhammad was twelve years old, he accompanied his uncle Abu Talib on a mercantile journey to Syria, and they proceeded as far as Busra. The journey lasted for some months. It was at Busra that the Christian monk Bahira met Muhammad. He is related to have said to Abu Talib: "Return with this boy and guard him against the hatred of the Jews, for a great career awaits your nephew."
