And We sent Messengers before thee, and We assigned to them wives, and seed; and it was not for any Messengers to bring a sign, but by God's leave. Every term has a Book. 38 Allah effaceth what He will, and establisheth (what He will), and with Him is the source of ordinance. 39 And We will either let you see part of what We threaten them with or cause you to die, for only the delivery of the message is (incumbent) on you, while calling (them) to account is Our (business). 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 Certain people who lived before plotted evil plans but God is the Master of all plans. He knows what every soul does. The unbelievers will soon learn who will achieve the blissful end. 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
