And assuredly We sent apostles before thee and We made for them wives and progeny, and it is not for an apostle to produce a verse except by the command of Allah; for every time there is a Book. 38 Allah effaceth what He will, and establisheth (what He will), and with Him is the source of ordinance. 39 Whether We allow you to see (the punishment) We have promised them, or end your life before (its execution), it is certainly for you to convey the message; the reckoning is for Us to do. 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 Those that were before them devised; but God's is the devising altogether. He knows what every soul earns. The unbelievers shall assuredly know whose will be the Ultimate Abode. 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
