And unto Allah belongeth the Unseen of the heavens and the earth, and the matter of the Hour (of Doom) is but as a twinkling of the eye, or it is nearer still. Lo! Allah is Able to do all things. 77 God brought you forth from the wombs of your mothers while you knew nothing, and gave you hearing and sight and hearts, so that you might be grateful. 78 Have they not seen the birds, subservient in the open skies? No one holds them up except Allah; indeed in this are signs for the people who believe. 79 Allah hath appointed for you from your houses a repose, and He hath appointed for you from the skins of the cattle houses which ye find light, on the day of your flitting and on the day of your stopping, and from their wools and their furs and their hair a furnishing and an enjoyment for a season. 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 If they still turn away, your duty is to warn them in clear terms. 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
