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 abrogates or confirms whatsoever He will, for He has with Him the Book of Books. 39 (O Prophet), whether We make you see a part of the punishment that We have threatened them with come to pass during your life-time, or We take you away before that happens, your duty is no more than to convey the Message, and it is for Us to make a reckoning. 40 Have they not seen how We come to the land diminishing it in its extremities? God judges; none repels His judgment; He is swift at the reckoning. 41 And verily, those before them did devise plots, but all planning is Allah's. He knows what every person earns, and the disbelievers will know who gets the good end (final destination). 42 They who disbelieve say: Thou art no messenger (of Allah). Say: Allah, and whosoever hath knowledge of the Scripture, is sufficient witness between me and you. 43
