And certainly We sent apostles before you and gave them wives and children, and it is not in (the power of) an apostle to bring a sign except by Allah's permission; for every term there is an appointment. 38 God abrogates or confirms what He pleases; with Him is the source of all commandments. 39 (O Prophet), whether We make you see a part of the punishment that We have threatened them with come to pass during your life-time, or We take you away before that happens, your duty is no more than to convey the Message, and it is for Us to make a reckoning. 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 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 have disbelieved say, "You are not a messenger." Say, [O Muhammad], "Sufficient is Allah as Witness between me and you, and [the witness of] whoever has knowledge of the Scripture." 43
