And We have already sent messengers before you and assigned to them wives and descendants. And it was not for a messenger to come with a sign except by permission of Allah. For every term is a decree. 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 Do they not see how We come to [their] land and shrink its borders? God decides, no one can reverse His decision, and He is swift in reckoning. 41 Now those who lived before these [sinners] did, too, devise many a blasphemy - but the most subtle devising is that of God, who knows what each human being deserves: and the deniers of the truth will [in time] come to know to whom the future belongs. 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
