We indeed sent many Messengers before you and We gave them wives and children; and no Messenger had the power to produce a miraculous sign except by the command of Allah. Every age has its own (revealed) Book. 38 Allah abolisheth whatsoever He will and keepeth; and with Him is the mother of the Book. 39 And whether We shew thee part of that which We have promised them, or We take thee away; on thee is only the preaching, and on Us is 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 who were before them plotted; but all plotting is Allah's. He knoweth that which each soul earneth. The disbelievers will come to know for whom will be the sequel of the (heavenly) Home. 42 The unbelievers say, 'Thou art not an Envoy.' Say: 'God suffices as a witness between me and you, and whosoever possesses knowledge of the Book.' 43
