And truly, We sent forth apostles before thee, and We appointed for them wives and offspring; and it was not given to any apostle to produce a miracle save at God's behest. Every age has had its revelation: 38 Allah effaceth what He will, and establisheth (what He will), and with Him is the source of ordinance. 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 Behold they not that We visit the land diminishing it by the borders; thereof Allah judgeth, and there is no reviser of His judgment, and He is swift in reckoning, 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 And those who disbelieve say: thou art not a sent one. Say thou: Allah is a sufficient witness between me and you, and also he with whom is knowledge of the Book. 43
