Then you have Abdul Muttalib, who is the head of Muhammad's, you could say, household, and he takes custody after the death of Amina. And he takes custody until Muhammad is eight years old when Abdul Muttalib dies. And then Muhammad's uncle, Abu Talib, takes custody. And it's under Abu Talib that Muhammad learns his trade as a merchant and as a trader. Now later on, we talk about Khadijah, who is a wealthy widow in Mecca, and she employs Muhammad, and according to Islamic tradition, is impressed by him, and proposes to him. And she's 15 years older than Muhammad. This is her third marriage, and Muhammad marries her.
