And indeed We sent Noble Messengers before you, and made wives and children for them; and it is not the task of any Noble Messenger to bring a sign except by Allah’s command; and all promises have a time prescribed. 38 God annuls or confirms whatever He wills [of His earlier messages] - for with Him is the source of all revelation. 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 [their] land and shrink its borders? God decides, no one can reverse His decision, and He is swift in reckoning. 41 Those that were before them devised; but God's is the devising altogether. He knows what every soul earns. The unbelievers shall assuredly know whose will be the Ultimate Abode. 42 The disbelievers say, “You are not a (Noble) Messenger (of Allah)”; proclaim, “Allah is a Sufficient Witness between me and you, and (so is) he who has knowledge of the Book.” 43
