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 Allah doth blot out or confirm what He pleaseth: with Him is the Mother of the Book. 39 Whether We show them (the unbelievers) to you facing the punishment with which We had threatened them, or make you die first (before its fulfillment), your duty is only to preach. It is up to Us to call them to account (for their deeds). 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 They who disbelieve say: Thou art no messenger (of Allah). Say: Allah, and whosoever hath knowledge of the Scripture, is sufficient witness between me and you. 43
