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 erases and confirms whatever He wills; and only with Him is the real script. 39 Whether We show you part of what We have promised them or cause you to pass away [before that], your mission is only to give warning; it is for Us to do the reckoning. 40 Have, then, they [who deny the truth] never yet seen how We visit the earth [with Our punishment,] gradually depriving it of all that is best thereon? For, [when] God judges, there is no power that could repel His judgment: and swift in reckoning is He! 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 They who disbelieve say: Thou art no messenger (of Allah). Say: Allah, and whosoever hath knowledge of the Scripture, is sufficient witness between me and you. 43
