And Allah's is the unseen of the heavens and the earth; and the matter of the hour is but as the twinkling of an eye or it is higher still; surely Allah has 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 controlled in the atmosphere of the sky? None holds them up except Allah. Indeed in that are signs 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 made for you out of that which He has created shades, and has made for you places of refuge in the mountains, and has made for you garments to protect you from the heat (and cold), and coats of mail to protect you from your (mutual) violence. Thus does He perfect His Grace unto you, that you may submit yourselves to His Will (in Islam). 81 But if they turn back, then on you devolves only the clear deliverance (of the message). 82 They [who turn away from it] are fully aware of God's blessings, but none the less they refuse to acknowledge them [as such,] since most of them are given to denying the truth. 83
