He's lying. In the correct periods would be chronological order. As in Mohammad was a child then he started aging until the end would be his death. He started out in the desert then he became the lacky of his first wife and drove wagons of trade goods for his first wife. He started islam and went to Mecah they tolerated him for awhile then drove him out and he had no choice because he didn't have a big following. He then went to Medina where 3 tribes of jews that didn't get along. Where he started robbing traders and eventually got a big enough following that he toppled one of the tribes in medina which got him more follower. He eventally took over medina robbed some more then took over Mecah using spy's and terror. Then he got poisoned by a slave he took and died.

The end.
