And Allah's is the unseen of the heavens and the earth; and the matter of the hour is but as the twinkling of an eye or it is higher still; surely Allah 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 Have they not regarded the birds, that are subjected in the air of heaven? Naught holds them but God; surely in that are signs for' a people who believe. 79 It is Allah Who made your habitations homes of rest and quiet for you; and made for you, out of the skins of animals, (tents for) dwellings, which ye find so light (and handy) when ye travel and when ye stop (in your travels); and out of their wool, and their soft fibres (between wool and hair), and their hair, rich stuff and articles of convenience (to serve you) for a time. 80 From the things He created, Allah has given you a covering shade, and He has made for you refuges in the mountains. He has given you garments to protect you from the heat, and garments to protect you from your own violence. As such it is that He perfects His favors upon you, in order that you submit. 81 (Muhammad), if they turn away, your only duty is to clearly preach to them. 82 They recognize the bounties of God but they refuse them and most of them are unbelievers. 83
