We have sent forth other Messengers before you and given them wives and descendants. Yet none of them could bring a sign except by the permission of Allah. Every term has its 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 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 See they not that We gradually reduce the land (in their control) from its outlying borders? (Where) Allah commands, there is none to put back His Command: and He is swift in calling to account. 41 Those before them did also devise plots; but in all things the master planning is God's. He knows what each soul does. Those who deny the truth shall soon know for whom is the final abode. 42 (Muhammad), the unbelievers say, "You are not a Messenger." Say, "God and those who have the knowledge of the Book are sufficient witness (to my prophethood)." 43
