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 Allah has brought you forth from your mothers' wombs when you knew nothing, and then gave you hearing, and sight and thinking hearts so that you may give thanks. 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 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 has provided shade for you out of some of the things He has created; and He has provided you with shelters in the mountains, and has given you coats that protect you from heat as well as coats that protect you in battle. Thus does He complete His favour upon you that you may submit to Him. 81 But if they turn away, your only duty is to clearly deliver the message of the truth. 82 They recognize the favors of Allah, then they disbelieve them; most of them are unbelievers. 83
