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 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 given you houses for staying, and made some houses from the hides of animals, which are easy for you on your day of travel and on the day of stopover – and from their wool, and fur, and hair, some household items and utilities for a while. 80 And Allah has provided you shade with the things He has created, and created for you refuge in the hills, and created some clothing for you to protect you from the heat, and some clothing to protect you during conflict; this is how He completes His favour upon you, so that you may obey. 81 Then, if they turn away, thy duty (O Muhammad) is but plain conveyance (of the message). 82 They recognize the favor of Allah, yet they deny it, and most of them are ungrateful. 83
