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 God produced you from your mothers' wombs knowing nothing, but gave you ears and eyes and hearts so that you may be grateful. 78 Do they not see the birds, constrained in the middle of the sky? None withholds them but Allah; most surely there are signs in this for a people who believe. 79 Allah has made your houses a repose, and has provided you with the skins of the cattle for your habitation which are light to handle both when you travel and when you camp; and out of their wool and their fur and their hair He has given you furnishings and goods for use over a period of time. 80 And it is God who has appointed for you coverings of the things He created, and He has appointed for you of the mountains refuges, and He has appointed for you shirts to protect you from the heat, and shirts to protect you from your own violence. Even so He perfects His blessing upon you, that haply you will surrender. 81 But if they turn away, you are responsible only for conveying the message clearly. 82 They are aware of the favours of Allah, and yet refuse to acknowledge them. Most of them are determined not to accept the Truth. 83
