Allah has full knowledge of the truths beyond the reach of perception both in the heavens and the earth; and the coming of the Hour will take no more than the twinkling of an eye; it may take even less. Indeed Allah has power 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 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 back, then on you devolves only the clear deliverance (of the message). 82 They recognize the blessing of God, then they deny it, and the most of them are the unthankful. 83
