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 And Allah has extracted you from the wombs of your mothers not knowing a thing, and He made for you hearing and vision and intellect that perhaps you would be grateful. 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 has given you houses for staying, and made some houses from the hides of animals, which are easy for you on your day of travel and on the day of stopover – and from their wool, and fur, and hair, some household items and utilities for a while. 80 And Allah has provided you shade with the things He has created, and created for you refuge in the hills, and created some clothing for you to protect you from the heat, and some clothing to protect you during conflict; this is how He completes His favour upon you, so that you may obey. 81 (Muhammad), if they turn away, your only duty is to clearly preach to them. 82 They recognize the bounties of God but they refuse them and most of them are unbelievers. 83
