And God's [alone] is the knowledge of the hidden reality of the heavens and the earth. And so, the advent of the Last Hour will but manifest itself [in a single moment,] like the twinkling of an eye, or closer still: for, behold, God has the power to will anything. 77 Allah brought you out of your mothers' wombs, and gave you hearing, sight and hearts, in order that you be thankful. 78 Have they not seen the birds obedient in mid-air? None holdeth them save Allah. Lo! herein, verily, are portents for a people who believe. 79 God has made your house the place for you to rest. He has also made homes for you out of the skins of cattle which are easy to carry along on a journey or at a camp. He has made wool, fur and the hair of cattle a temporary means of enjoyment for you. 80 From the things He created, Allah has given you a covering shade, and He has made for you refuges in the mountains. He has given you garments to protect you from the heat, and garments to protect you from your own violence. As such it is that He perfects His favors upon you, in order that you submit. 81 Then if they turn away, O dear Prophet, (Mohammed – peace and blessings be upon him) upon you is nothing but to clearly convey (the message). 82 They do know the favours of God, and yet they deny them, for most of them are not grateful. 83
