To God belongs all the secrets of the heavens and the earth. It only takes God a twinkling of an eye or even less to make it the Day of Judgment. God has power over all things. 77 It is He Who brought you forth from the wombs of your mothers when ye knew nothing; and He gave you hearing and sight and intelligence and affections: that ye may give thanks (to Allah). 78 Do you not see the birds held high between the heavens and the earth? Nothing holds them (aloft) but God. There are verily signs in this for those 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 From the things He created, Allah has given you a covering shade, and He has made for you refuges in the mountains. He has given you garments to protect you from the heat, and garments to protect you from your own violence. As such it is that He perfects His favors upon you, in order that you submit. 81 Then if they turn away, on thee is only the preaching plain. 82 They know the favour of Allah and then deny it. Most of them are ingrates. 83
