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 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 And Allah has given you a place to abide in your houses, and He has given you tents of the skins of cattle which you find light to carry on the day of your march and on the day of your halting, and of their wool and their fur and their hair (He has given you) household stuff and a provision for a time. 80 And it is God who has appointed for you coverings of the things He created, and He has appointed for you of the mountains refuges, and He has appointed for you shirts to protect you from the heat, and shirts to protect you from your own violence. Even so He perfects His blessing upon you, that haply you will surrender. 81 But if they turn away, your only duty is to clearly deliver the message of the truth. 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
