We have sent forth other Messengers before you and given them wives and descendants. Yet none of them could bring a sign except by the permission of Allah. Every term has its Book. 38 God blots out, and He establishes whatsoever He will; and with Him is the Essence of the Book. 39 BUT WHETHER We let thee see [in thy lifetime, O Prophet, the fulfilment of] some of what We have promised them, or whether We cause thee to die [before its fulfilment] - thy duty is no more than to deliver the message; and the reckoning is Ours. 40 Do they not see how We come to [their] land and shrink its borders? God decides, no one can reverse His decision, and He is swift in reckoning. 41 And of a surety there plotted those before them; but unto Allah belongeth the plotting entirely. He knoweth that which each soul earneth. And anon will the infidels know for whom is the happy ending of the Abode. 42 And those who disbelieve say: You are not a messenger. Say: Allah is sufficient as a witness between me and you and whoever has knowledge of the Book. 43
