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 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 that We set upon the land, reducing it from its borders? And Allah decides; there is no adjuster of His decision. And He is swift in account. 41 And verily, those before them did devise plots, but all planning is Allah's. He knows what every person earns, and the disbelievers will know who gets the good end (final destination). 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
