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 Allah has brought you forth from your mothers' wombs when you knew nothing, and then gave you hearing, and sight and thinking hearts so that you may give thanks. 78 Behold they not the birds subjected in the firmament of the heaven? Naught supporteth them save Allah; verily therein are signs for people 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 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 know the favour of Allah and then deny it. Most of them are ingrates. 83
