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 it is God who brought you forth from your mothers' wombs, and He appointed for you hearing, and sight, and hearts, that haply so you will be thankful. 78 Have, then, they [who deny the truth] never considered the birds, enabled [by God] to fly in mid-air, with none but God holding them aloft? In this, behold, there are messages indeed for people who will 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 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 (Muhammad), if they turn away, your only duty is to clearly preach to them. 82 They recognise the Grace of Allah, yet they deny it (by worshipping others besides Allah) and most of them are disbelievers (deny the Prophethood of Muhammad SAW). 83
