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 Allah blots out, and He establishes what He will. With Him is the Essence of the Book. 39 Whether We show thee a part of that We promise them, or We call thee to Us, it is thine only to deliver the Message, and 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 Those before them did (also) devise plots; but in all things the master-planning is Allah's He knoweth the doings of every soul: and soon will the Unbelievers know who gets home in the end. 42 Those who disbelieve say: 'You are not a Messenger' Say: 'Allah is a Sufficient witness between me and you, and whosoever possess knowledge of the Book' 43
