And to Allah belongs the unseen [aspects] of the heavens and the earth. And the command for the Hour is not but as a glance of the eye or even nearer. Indeed, Allah is over all things competent. 77 And Allah has brought you out from the wombs of your mothers while you know nothing. And He gave you hearing, sight, and hearts that you might give thanks (to Allah). 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 God has given you homes to live in, and tents (made) from the hides of cattle convenient for days of travelling and halting; and from their wool and fur and hair you make domestic articles and goods that last a certain time. 80 God has granted you shade out of what He has created, places of shelter in the mountains, garments with which to protect yourselves from the heat and coats of mail to shield you in battle. Thus He completes His favour to you, so that you may submit wholly to Him. 81 But if they turn away, you are responsible only for conveying the message clearly. 82 They recognise the favours of Allah; then they deny them; and most of them are (creatures) ungrateful. 83
