We sent Messengers before you (Muhammad) and gave them wives and offspring. No Messenger was to show miracles without the permission of God. 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 part of what We have promised them or cause you to pass away [before that], your mission is only to give warning; it is for Us to do 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 who were before them plotted; but all plotting is Allah's. He knoweth that which each soul earneth. The disbelievers will come to know for whom will be the sequel of the (heavenly) Home. 42 (Muhammad), the unbelievers say, "You are not a Messenger." Say, "God and those who have the knowledge of the Book are sufficient witness (to my prophethood)." 43
