To God belong the secrets of the heavens and the earth, and the Hour of Doom is a matter of the winking of an eye, even less, for God has certainly power over all things. 77 When God brought you out of your mothers wombs, you knew nothing. He gave you ears, eyes, and hearts so that perhaps you would give Him thanks. 78 Do they not see the birds held (flying) in the midst of the sky? None holds them but Allah [none gave them the ability to fly but Allah]. Verily, in this are clear proofs and signs for people who believe (in the Oneness of Allah). 79 It is Allah Who made your habitations homes of rest and quiet for you; and made for you, out of the skins of animals, (tents for) dwellings, which ye find so light (and handy) when ye travel and when ye stop (in your travels); and out of their wool, and their soft fibres (between wool and hair), and their hair, rich stuff and articles of convenience (to serve you) for a time. 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, thy duty (O Muhammad) is but plain conveyance (of the message). 82 They recognize the favour of God, yet they deny it; and most of them are ungrateful. 83
