We sent down messengers before you and gave them wives and children. Yet it was not possible for a messenger to bring a sign, save by the command of God. Every age has had its revelation. 38 For every event God has ordained His decree. God establishes or effaces whatever He wants and with Him is the original of the Book. 39 Whether We let thee see something of that which We have promised them, or make thee die (before its happening), thine is but conveyance (of the message). Ours the reckoning. 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 Certain people who lived before plotted evil plans but God is the Master of all plans. He knows what every soul does. The unbelievers will soon learn who will achieve the blissful end. 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
