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 blots out, and He establishes what He will. With Him is the Essence of the Book. 39 And whether We shew thee part of that which We have promised them, or We take thee away; on thee is only the preaching, and on Us is the reckoning. 40 Do they not see how We come to the land and reduce its extremities? Allah judges; none repel His judgement. Swift is His 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
