We did send messengers before thee, and appointed for them wives and children: and it was never the part of a messenger to bring a sign except as Allah permitted (or commanded). For each period is a Book (revealed). 38 Allah blots out, and He establishes what He will. With Him is the Essence of the Book. 39 Whether We show thee a part of that We promise them, or We call thee to Us, it is thine only to deliver the Message, and Ours the reckoning. 40 Have they not seen how We come to the land diminishing it in its extremities? God judges; none repels His judgment; He is swift at the reckoning. 41 Those before them did (also) devise plots; but in all things the master-planning is Allah's He knoweth the doings of every soul: and soon will the Unbelievers know who gets home in the end. 42 Those who disbelieve say: 'You are not a Messenger' Say: 'Allah is a Sufficient witness between me and you, and whosoever possess knowledge of the Book' 43
