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 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 Yet those who are disbelievers say: "You are not the apostle sent (by God)." Tell them: "God is sufficient as witness between me and you, and he who has knowledge of the Book." 43
