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 effaceth what He will, and establisheth (what He will), and with Him is the source of ordinance. 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 Do they not perceive that We are reducing their dwellings from all directions? And Allah gives the command – there is none that can postpone His command; and He spends no time in taking account. 41 Now those who lived before these [sinners] did, too, devise many a blasphemy - but the most subtle devising is that of God, who knows what each human being deserves: and the deniers of the truth will [in time] come to know to whom the future belongs. 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
