We sent Messengers before you (Muhammad) and gave them wives and offspring. No Messenger was to show miracles without the permission of God. 38 God blots out, and He establishes whatsoever He will; and with Him is the Essence of the Book. 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 Do they not see how We come to the land and reduce its extremities? Allah judges; none repel His judgement. Swift is His reckoning. 41 Those who have gone before them devised, but to Allah is the devising altogether. He knows what every soul earns. The unbelievers shall know without doubt for whom is the Ultimate Abode. 42 And those who disbelieve, say: "You (O Muhammad SAW) are not a Messenger." Say: "Sufficient for a witness between me and you is Allah and those too who have knowledge of the Scripture (such as 'Abdullah bin Salam and other Jews and Christians who embraced Islam)." 43
