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 Allah makes to pass away and establishes what He pleases, and with Him is the basis of the Book. 39 Whether We let thee see something of that which We have promised them, or make thee die (before its happening), thine is but conveyance (of the message). Ours the reckoning. 40 Do they not see that We are advancing in the land, diminishing it by its borders on all sides? Allah judges, and no one has the power to reverse His judgement. 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 (Muhammad), the unbelievers say, "You are not a Messenger." Say, "God and those who have the knowledge of the Book are sufficient witness (to my prophethood)." 43
