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 blots out what He wills and confirms (what He wills). And with Him is the Mother of the Book (Al-Lauh Al-Mahfuz) 39 And whether We shew thee part of that which We have promised them, or We take thee away; on thee is only the preaching, and on Us is 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 Surely those who had gone before them had also plotted; but God's is all the planning, for He has knowledge of what each does. The unbelievers will soon learn for whom is the guerdon of Paradise. 42 And those who disbelieve, say: "You (O Muhammad SAW) are not a Messenger." Say: "Sufficient for a witness between me and you is Allah and those too who have knowledge of the Scripture (such as 'Abdullah bin Salam and other Jews and Christians who embraced Islam)." 43
