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 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 Behold they not the birds subjected in the firmament of the heaven? Naught supporteth them save Allah; verily therein are signs for people who believe. 79 God has made your house the place for you to rest. He has also made homes for you out of the skins of cattle which are easy to carry along on a journey or at a camp. He has made wool, fur and the hair of cattle a temporary means of enjoyment for you. 80 And Allah hath appointed for you, of that which He hath created shades, and He hath appointed for you from the mountains places of retreat, and He hath appointed for you coats protecting you from the heat and coats protecting you from the violence. Thus He perfecteth His favour on you that haply ye may submit. 81 (Muhammad), if they turn away, your only duty is to clearly preach to them. 82 They recognize the blessing of God, then they deny it, and the most of them are the unthankful. 83
