And Allah's is the Unseen of the heavens and the earth, and the affair of the Hour will be not but as a flash of the eye, or it is even nearer, verily Allah is over everything Potent. 77 And Allah has brought you forth from the wombs of your mothers-- you did not know anything-- and He gave you hearing and sight and hearts 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 from your homes a place of rest and made for you from the hides of the animals tents which you find light on your day of travel and your day of encampment; and from their wool, fur and hair is furnishing and enjoyment for a time. 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 (Muhammad), if they turn away, your only duty is to clearly preach to them. 82 They recognize the favour of God, yet they deny it; and most of them are ungrateful. 83
