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 doth blot out or confirm what He pleaseth: with Him is the Mother of the Book. 39 And We will either let you see part of what We threaten them with or cause you to die, for only the delivery of the message is (incumbent) on you, while calling (them) to account is Our (business). 40 Have they not seen how We come to the land diminishing it in its extremities? God judges; none repels His judgment; He is swift at the 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 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
