And indeed We sent Messengers before you (O Muhammad SAW), and made for them wives and offspring. And it was not for a Messenger to bring a sign except by Allah's Leave. (For) each and every matter there is a Decree (from Allah). 38 Allah effaceth what He will, and establisheth (what He will), and with Him is the source of ordinance. 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 Surely those who had gone before them had also plotted; but God's is all the planning, for He has knowledge of what each does. The unbelievers will soon learn for whom is the guerdon of Paradise. 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
