And truly, We sent forth apostles before thee, and We appointed for them wives and offspring; and it was not given to any apostle to produce a miracle save at God's behest. Every age has had its revelation: 38 God abrogates or confirms whatsoever He will, for He has with Him the Book of Books. 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 that We gradually reduce the land (in their control) from its outlying borders? (Where) Allah commands, there is none to put back His Command: and He is swift in calling to account. 41 And of a surety there plotted those before them; but unto Allah belongeth the plotting entirely. He knoweth that which each soul earneth. And anon will the infidels know for whom is the happy ending of the Abode. 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
