And indeed We sent Messengers before you (O Muhammad SAW), and made for them wives and offspring. And it was not for a Messenger to bring a sign except by Allah's Leave. (For) each and every matter there is a Decree (from Allah). 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 Have they not seen that We set upon the land, reducing it from its borders? And Allah decides; there is no adjuster of His decision. And He is swift in account. 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 Those who deny the truth say, "You are not God's messenger." Say, "Sufficient is God as my witness between me and you, and those who have knowledge of the Book." 43
