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 Allah makes to pass away and establishes what He pleases, and with Him is the basis of the Book. 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, then, they [who deny the truth] never yet seen how We visit the earth [with Our punishment,] gradually depriving it of all that is best thereon? For, [when] God judges, there is no power that could repel His judgment: and swift in reckoning is He! 41 And those before them did indeed make plans, but all planning is Allah's; He knows what every soul earns, and the unbelievers shall come to know for whom is the (better) issue of the abode. 42 And those who disbelieve say: You are not a messenger. Say: Allah is sufficient as a witness between me and you and whoever has knowledge of the Book. 43
