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 God abrogates or confirms what He pleases; with Him is the source of all commandments. 39 Whether We show you part of that We promise them, or We call you to Us, it is only for you to deliver the Message, and Ours is the accounting. 40 Have they not considered that We have taken over the land and reduced its borders? It is God who issues the irreversible decree and His reckoning is swift. 41 Those who lived before them also devised many a plot, but the master plot rests with Allah. He knows what everyone does. The deniers of the truth will soon come to know whose end is good. 42 Yet those who are disbelievers say: "You are not the apostle sent (by God)." Tell them: "God is sufficient as witness between me and you, and he who has knowledge of the Book." 43
