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 God brought you forth from the wombs of your mothers while you knew nothing, and gave you hearing and sight and hearts, so that you might be grateful. 78 Do they not look at the birds, held poised in the midst of (the air and) the sky? Nothing holds them up but (the power of) Allah. Verily in this are signs for those who believe. 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 made for you out of that which He has created shades, and has made for you places of refuge in the mountains, and has made for you garments to protect you from the heat (and cold), and coats of mail to protect you from your (mutual) violence. Thus does He perfect His Grace unto you, that you may submit yourselves to His Will (in Islam). 81 Then, if they turn away, thy duty (O Muhammad) is but plain conveyance (of the message). 82 They do know the favours of God, and yet they deny them, for most of them are not grateful. 83
