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 what He wills and confirms (what He wills). And with Him is the Mother of the Book (Al-Lauh Al-Mahfuz) 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 Behold they not that We visit the land diminishing it by the borders; thereof Allah judgeth, and there is no reviser of His judgment, and He is swift in reckoning, 41 Those who lived before them also devised many a plot, but the master plot rests with Allah. He knows what everyone does. The deniers of the truth will soon come to know whose end is good. 42 And those who disbelieve say: You are not a messenger. Say: Allah is sufficient as a witness between me and you and whoever has knowledge of the Book. 43
