We did send messengers before thee, and appointed for them wives and children: and it was never the part of a messenger to bring a sign except as Allah permitted (or commanded). For each period is a Book (revealed). 38 God abrogates or confirms what He pleases; with Him is the source of all commandments. 39 And whether We show you a promise that is given to them, or call you to Us before it – so in any case, upon you is just the conveyance*, and for Us is the taking of the account. (* Of the message.) 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 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 They who disbelieve say: Thou art no messenger (of Allah). Say: Allah, and whosoever hath knowledge of the Scripture, is sufficient witness between me and you. 43
