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 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 that are subjected in the air of the heaven? Nothing holds them except Allah. Surely, in this are signs for those who believe. 79 God has made your house the place for you to rest. He has also made homes for you out of the skins of cattle which are easy to carry along on a journey or at a camp. He has made wool, fur and the hair of cattle a temporary means of enjoyment for you. 80 And Allah hath given you, of that which He hath created, shelter from the sun; and hath given you places of refuge in the mountains, and hath given you coats to ward off the heat from you, and coats (of armour) to save you from your own foolhardiness. Thus doth He perfect His favour unto you, in order that ye may surrender (unto Him). 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
