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 Have they not seen the birds obedient in mid-air? None holdeth them save Allah. Lo! herein, verily, are portents for a people who believe. 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 And Allah has provided shade for you out of some of the things He has created; and He has provided you with shelters in the mountains, and has given you coats that protect you from heat as well as coats that protect you in battle. Thus does He complete His favour upon you that you may submit to Him. 81 Then, if they turn away, thy duty (O Muhammad) is but plain conveyance (of the message). 82 They recognize the blessing of God, then they deny it, and the most of them are the unthankful. 83
