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 doth blot out or confirm what He pleaseth: with Him is the Mother of the Book. 39 And We will either let you see part of what We threaten them with or cause you to die, for only the delivery of the message is (incumbent) on you, while calling (them) to account is Our (business). 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 Those before them did also devise plots; but in all things the master planning is God's. He knows what each soul does. Those who deny the truth shall soon know for whom is the final 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
