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 forth from the wombs of your mothers-- you did not know anything-- and He gave you hearing and sight and hearts that you may give thanks. 78 Have they never noticed the birds how they are held under control in the middle of the sky, where none holds them (from falling) except Allah? Surely there are signs in this for those 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 And Allah has provided shade for you out of some of the things He has created; and He has provided you with shelters in the mountains, and has given you coats that protect you from heat as well as coats that protect you in battle. Thus does He complete His favour upon you that you may submit to Him. 81 But if they turn away, thy duty is only to preach the clear Message. 82 They recognize the favor of Allah; then they deny it. And most of them are disbelievers. 83
