We sent down messengers before you and gave them wives and children. Yet it was not possible for a messenger to bring a sign, save by the command of God. Every age has had its revelation. 38 Allah doth blot out or confirm what He pleaseth: with Him is the Mother of the Book. 39 And We will either let you see part of what We threaten them with or cause you to die, for only the delivery of the message is (incumbent) on you, while calling (them) to account is Our (business). 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 And of a surety there plotted those before them; but unto Allah belongeth the plotting entirely. He knoweth that which each soul earneth. And anon will the infidels know for whom is the happy ending of the Abode. 42 And those who have disbelieved say, "You are not a messenger." Say, [O Muhammad], "Sufficient is Allah as Witness between me and you, and [the witness of] whoever has knowledge of the Scripture." 43
