And indeed We sent Noble Messengers before you, and made wives and children for them; and it is not the task of any Noble Messenger to bring a sign except by Allah’s command; and all promises have a time prescribed. 38 Allah effaceth what He will, and establisheth (what He will), and with Him is the source of ordinance. 39 And whether We show you part of what We promise them or take you in death, upon you is only the [duty of] notification, and upon Us is the account. 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
