Muhammad, son of Abdullah, son of Abdul Muttalib, of the tribe of Quraysh, was born in Makkah fifty-three years before the Hijrah. His father died before he was born, and he was protected first by his grandfather, Abdul Muttalib, and after his grandfather’s death, by his uncle Abu Talib.
As a young boy he traveled with his uncle in the merchants’ caravan to Syria, and some years afterwards made the same journey in the service of a wealthy widow named Khadijah. So faithfully did he transact the widow’s business, and so excellent was the report of his behavior, which she received from her old servant who had accompanied him, that she soon afterwards married her young agent; and the marriage proved a very happy one, though she was fifteen years older than he was. Throughout the twenty-six years of their life together he remained devoted to her; and after her death, when he took other wives he always mentioned her with the greatest love and reverence. This marriage gave him rank among the notables of Makkah, while his conduct earned for him the surname Al-Amin, the “trustworthy.”
