And We have already sent messengers before you and assigned to them wives and descendants. And it was not for a messenger to come with a sign except by permission of Allah. For every term is a decree. 38 God abrogates or confirms whatsoever He will, for He has with Him the Book of Books. 39 Whether We allow you to see (the punishment) We have promised them, or end your life before (its execution), it is certainly for you to convey the message; the reckoning is for Us to do. 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 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
