We indeed sent many Messengers before you and We gave them wives and children; and no Messenger had the power to produce a miraculous sign except by the command of Allah. Every age has its own (revealed) Book. 38 God abrogates or confirms whatsoever He will, for He has with Him the Book of Books. 39 Whether We show them (the unbelievers) to you facing the punishment with which We had threatened them, or make you die first (before its fulfillment), your duty is only to preach. It is up to Us to call them to account (for their deeds). 40 See they not that We gradually reduce the land (of disbelievers, by giving it to the believers, in war victories) from its outlying borders. And Allah judges, there is none to put back His Judgement and He is Swift at reckoning. 41 And those before them had plotted, but to Allah belongs the plan entirely. He knows what every soul earns, and the disbelievers will know for whom is the final home. 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
