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 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 Have they not seen the birds obedient in mid-air? None holdeth them save Allah. Lo! herein, verily, are portents for a people who believe. 79 Allah has made your houses a repose, and has provided you with the skins of the cattle for your habitation which are light to handle both when you travel and when you camp; and out of their wool and their fur and their hair He has given you furnishings and goods for use over a period of time. 80 And Allah hath given you, of that which He hath created, shelter from the sun; and hath given you places of refuge in the mountains, and hath given you coats to ward off the heat from you, and coats (of armour) to save you from your own foolhardiness. Thus doth He perfect His favour unto you, in order that ye may surrender (unto Him). 81 BUT IF they turn away [from thee, O Prophet, remember that] thy only duty is a clear delivery of the message [entrusted to thee]. 82 They know the favour of Allah and then deny it. Most of them are ingrates. 83
