Abu Hurairah narrated that the Messenger of Allah said:"Sulaiman bin Dawud said: 'Tonight I will go around ninety women, each of whom will bear a horseman who will perform Jihad in the cause of Allah.' His companion said to him: 'If Allah wills.' But he did not say: 'If Allah wills.' Then he went around to them all, but none of them got pregnant except a woman who bore half a man. By the One in Whose Hand is my soul! If he had said, 'If Allah wills,' they would all have performed Jihad in the cause of Allah as horsemen
