We indeed sent many Messengers before you and We gave them wives and children; and no Messenger had the power to produce a miraculous sign except by the command of Allah. Every age has its own (revealed) Book. 38 God abrogates or confirms what He pleases; with Him is the source of all commandments. 39 Whether We let thee see something of that which We have promised them, or make thee die (before its happening), thine is but conveyance (of the message). Ours the 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 those before them had plotted, but to Allah belongs the plan entirely. He knows what every soul earns, and the disbelievers will know for whom is the final home. 42 The unbelievers say, 'Thou art not an Envoy.' Say: 'God suffices as a witness between me and you, and whosoever possesses knowledge of the Book.' 43
