We sent Messengers before you (Muhammad) and gave them wives and offspring. No Messenger was to show miracles without the permission of God. 38 Allah effaces whatever He wills and retains whatever He wills. With Him is the Mother of the Book. 39 Whether We show you part of what We have promised them or cause you to pass away [before that], your mission is only to give warning; it is for Us to do the reckoning. 40 Behold they not that We visit the land diminishing it by the borders; thereof Allah judgeth, and there is no reviser of His judgment, and He is swift in reckoning, 41 Surely those who had gone before them had also plotted; but God's is all the planning, for He has knowledge of what each does. The unbelievers will soon learn for whom is the guerdon of Paradise. 42 The Unbelievers say: "No messenger art thou." Say: "Enough for a witness between me and you is Allah, and such as have knowledge of the Book." 43
