We sent down messengers before you and gave them wives and children. Yet it was not possible for a messenger to bring a sign, save by the command of God. Every age has had its revelation. 38 Allah abolisheth whatsoever He will and keepeth; and with Him is the mother of the Book. 39 Whether We show them (the unbelievers) to you facing the punishment with which We had threatened them, or make you die first (before its fulfillment), your duty is only to preach. It is up to Us to call them to account (for their deeds). 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 And those who disbelieve, say: "You (O Muhammad SAW) are not a Messenger." Say: "Sufficient for a witness between me and you is Allah and those too who have knowledge of the Scripture (such as 'Abdullah bin Salam and other Jews and Christians who embraced Islam)." 43
