And indeed We sent Noble Messengers before you, and made wives and children for them; and it is not the task of any Noble Messenger to bring a sign except by Allah’s command; and all promises have a time prescribed. 38 God abrogates or confirms whatsoever He will, for He has with Him the Book of Books. 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 the land and reduce its extremities? Allah judges; none repel His judgement. Swift is His reckoning. 41 And indeed those before them had plotted; therefore Allah Himself is the Master of all strategies; He knows all what every soul earns; and soon will the disbelievers realise for whom is the final abode. 42 And those who have disbelieved say, "You are not a messenger." Say, [O Muhammad], "Sufficient is Allah as Witness between me and you, and [the witness of] whoever has knowledge of the Scripture." 43
