We indeed sent many Messengers before you and We gave them wives and children; and no Messenger had the power to produce a miraculous sign except by the command of Allah. Every age has its own (revealed) Book. 38 Allah effaces whatever He wills and retains whatever He wills. With Him is the Mother of the Book. 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 Have they not considered that We have taken over the land and reduced its borders? It is God who issues the irreversible decree and His reckoning is swift. 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 Those who deny the truth say, "You are not God's messenger." Say, "Sufficient is God as my witness between me and you, and those who have knowledge of the Book." 43
