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 annuls or confirms whatever He wills [of His earlier messages] - for with Him is the source of all revelation. 39 Whether We show you part of that We promise them, or We call you to Us, it is only for you to deliver the Message, and Ours is the accounting. 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 And those before them did indeed make plans, but all planning is Allah's; He knows what every soul earns, and the unbelievers shall come to know for whom is the (better) issue of the abode. 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
