To God belong the secrets of the heavens and the earth, and the Hour of Doom is a matter of the winking of an eye, even less, for God has certainly power over all things. 77 When God brought you out of your mothers wombs, you knew nothing. He gave you ears, eyes, and hearts so that perhaps you would give Him thanks. 78 Do they not see the birds held (flying) in the midst of the sky? None holds them but Allah [none gave them the ability to fly but Allah]. Verily, in this are clear proofs and signs for people who believe (in the Oneness of Allah). 79 And Allah hath given you in your houses an abode, and hath given you (also), of the hides of cattle, houses which ye find light (to carry) on the day of migration and on the day of pitching camp; and of their wool and their fur and their hair, caparison and comfort for a while. 80 God has given you of things created, shade, and places of shelter in the mountains, and clothes for protection against the heat, and coats (of mail) for defence during war. He thus bestows His favours on you so that you may be grateful to Him. 81 Then, if they turn away, thy duty (O Muhammad) is but plain conveyance (of the message). 82 They recognize the favour of Allah, then they deny it, and most of them are infidels. 83
