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 blots out, and He establishes what He will. With Him is the Essence of the Book. 39 Whether We show you (O Muhammad SAW) part of what We have promised them or cause you to die, your duty is only to convey (the Message) and on Us is the reckoning. 40 See they not how we aim to the land, reducing it of its outlying parts? (When) Allah doometh there is none that can postpone His doom, and He is swift at 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
