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 annuls or confirms whatever He wills [of His earlier messages] - for with Him is the source of all revelation. 39 (O Prophet), whether We make you see a part of the punishment that We have threatened them with come to pass during your life-time, or We take you away before that happens, your duty is no more than to convey the Message, and it is for Us to make a reckoning. 40 Have they not seen that We set upon the land, reducing it from its borders? And Allah decides; there is no adjuster of His decision. And He is swift in account. 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 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
