And We sent Messengers before thee, and We assigned to them wives, and seed; and it was not for any Messengers to bring a sign, but by God's leave. Every term has a Book. 38 Allah makes to pass away and establishes what He pleases, and with Him is the basis of the Book. 39 And whether We show you part of what We promise them or take you in death, upon you is only the [duty of] notification, and upon Us is the account. 40 Do they not see how We come to [their] land and shrink its borders? God decides, no one can reverse His decision, 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 (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
