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 God blots out, and He establishes whatsoever He will; and with Him is the Essence 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 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 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 deny the truth say, "You are not God's messenger." Say, "Sufficient is God as my witness between me and you, and those who have knowledge of the Book." 43
