And to Allah belongs the unseen of the heavens and the earth. And the matter of the Hour is not but as a twinkling of the eye, or even nearer. Truly! Allah is Able to do all things. 77 It is He Who brought you forth from the wombs of your mothers when ye knew nothing; and He gave you hearing and sight and intelligence and affections: that ye may give thanks (to Allah). 78 Do they not look at the birds, held poised in the midst of (the air and) the sky? Nothing holds them up but (the power of) Allah. Verily in this are signs for those who believe. 79 And it is God who has appointed a place of rest for you of your houses, and He has appointed for you of the skins of the cattle houses you find light on the day that you journey, and on the day you abide, and of their wool, and of their fur, and of their hair furnishing and an enjoyment for a while. 80 And Allah has made for you of what He has created shelters, and He has given you in the mountains places of retreat, and He has given you garments to preserve you from the heat and coats of mail to preserve you in your fighting; even thus does He complete His favor upon you, that haply you may submit. 81 But if they turn away, [O Muhammad] - then only upon you is [responsibility for] clear notification. 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
