And certainly We sent apostles before you and gave them wives and children, and it is not in (the power of) an apostle to bring a sign except by Allah's permission; for every term there is an appointment. 38 Allah abolisheth whatsoever He will and keepeth; and with Him is the mother 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 considered that We have taken over the land and reduced its borders? It is God who issues the irreversible decree and His reckoning is swift. 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 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
