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 effaceth what He will, and establisheth (what He will), and with Him is the source of ordinance. 39 Whether We let thee see something of that which We have promised them, or make thee die (before its happening), thine is but conveyance (of the message). Ours the reckoning. 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 who lived before them also devised many a plot, but the master plot rests with Allah. He knows what everyone does. The deniers of the truth will soon come to know whose end is good. 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
