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 brought you out of your mothers' wombs, and gave you hearing, sight and hearts, in order that you be thankful. 78 Have you not considered the free movements of the birds high in the sky above? What keeps them aloft except God? In this there is evidence (of the truth) for the believing people. 79 And Allah has made for you in your homes an abode, and made for you out of the hides of the cattle (tents for) dwelling, which you find so light (and handy) when you travel and when you stay (in your travels), and of their wool, fur, and hair (sheep wool, camel fur, and goat hair), a furnishing and articles of convenience (e.g. carpets, blankets, etc.), a comfort for a while. 80 It is Allah Who made out of the things He created, some things to give you shade; of the hills He made some for your shelter; He made you garments to protect you from heat, and coats of mail to protect you from your (mutual) violence. Thus does He complete His favours on you, that ye may bow to His Will (in Islam). 81 If they still turn away, your duty is to warn them in clear terms. 82 They recognize the favor of Allah, yet they deny it, and most of them are ungrateful. 83
