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 Allah abolisheth whatsoever He will and keepeth; and with Him is the mother of the Book. 39 Whether We show you part of that We promise them, or We call you to Us, it is only for you to deliver the Message, and Ours is the accounting. 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 Allah's He knoweth the doings of every soul: and soon will the Unbelievers know who gets home in the end. 42 The Unbelievers say: "No messenger art thou." Say: "Enough for a witness between me and you is Allah, and such as have knowledge of the Book." 43
