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 eliminates what He wills or confirms, and with Him is the Mother of the Book. 39 And We will either let you see part of what We threaten them with or cause you to die, for only the delivery of the message is (incumbent) on you, while calling (them) to account is Our (business). 40 Have they not seen how We come to the land diminishing it in its extremities? God judges; none repels His judgment; He is swift at the reckoning. 41 Certain people who lived before plotted evil plans but God is the Master of all plans. He knows what every soul does. The unbelievers will soon learn who will achieve the blissful end. 42 Those who disbelieve say: 'You are not a Messenger' Say: 'Allah is a Sufficient witness between me and you, and whosoever possess knowledge of the Book' 43
