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 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, constrained in the middle of the sky? None withholds them but Allah; most surely there are signs in this for a people who believe. 79 And Allah has made for you in your homes an abode, and made for you out of the hides of the cattle (tents for) dwelling, which you find so light (and handy) when you travel and when you stay (in your travels), and of their wool, fur, and hair (sheep wool, camel fur, and goat hair), a furnishing and articles of convenience (e.g. carpets, blankets, etc.), a comfort for a while. 80 And Allah hath appointed for you, of that which He hath created shades, and He hath appointed for you from the mountains places of retreat, and He hath appointed for you coats protecting you from the heat and coats protecting you from the violence. Thus He perfecteth His favour on you that haply ye may submit. 81 BUT IF they turn away [from thee, O Prophet, remember that] thy only duty is a clear delivery of the message [entrusted to thee]. 82 They recognize the favour of God, yet they deny it; and most of them are ungrateful. 83
