will become strong, but one of his commanders will become even stronger than he and will rule his own kingdom with great power. The daughter [Fatimah] of the king of the South [Mohammed] will go to the king of the North [Muawiyah] to make an alliance, but she will not retain her power, and he and his power will not last. Dan 11:6

Watch for more pieces that fit.  Blessed is the one who looks.
