To God belongs the Unseen in the heavens and in the earth. And the matter of the Hour is as a twinkling of the eye, or nearer. Surely God is powerful over everything. 77 And it is God who brought you forth from your mothers' wombs, and He appointed for you hearing, and sight, and hearts, that haply so you will be thankful. 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 God has provided shade for you out of what He has created and places of retreat out of mountains. He has given you garments to protect you from the heat and cover your private parts. This is how He perfects His bounties to you so that perhaps you would submit to His will. 81 But if they turn away, your only duty is to clearly deliver the message of the truth. 82 They know the favour of Allah and then deny it. Most of them are ingrates. 83
