And assuredly We sent apostles before thee and We made for them wives and progeny, and it is not for an apostle to produce a verse except by the command of Allah; for every time there is a Book. 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 Those before them did also devise plots; but in all things the master planning is God's. He knows what each soul does. Those who deny the truth shall soon know for whom is the final abode. 42 The unbelievers claim that you have not been sent by Allah. Tell them: "Allah is sufficient as a witness between me and you; and so also do those who know the Scriptures." 43
