And truly, We sent forth apostles before thee, and We appointed for them wives and offspring; and it was not given to any apostle to produce a miracle save at God's behest. Every age has had its revelation: 38 Allah blots out what He wills and confirms (what He wills). And with Him is the Mother of the Book (Al-Lauh Al-Mahfuz) 39 BUT WHETHER We let thee see [in thy lifetime, O Prophet, the fulfilment of] some of what We have promised them, or whether We cause thee to die [before its fulfilment] - thy duty is no more than to deliver the message; and the reckoning is Ours. 40 Do they not see how We come to [their] land and shrink its borders? God decides, no one can reverse His decision, and He is swift in reckoning. 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 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
