To God belong the secrets of the heavens and the earth, and the Hour of Doom is a matter of the winking of an eye, even less, for God has certainly power over all things. 77 And Allah has extracted you from the wombs of your mothers not knowing a thing, and He made for you hearing and vision and intellect that perhaps you would be grateful. 78 Do you not see the birds held high between the heavens and the earth? Nothing holds them (aloft) but God. There are verily 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 God has granted you shade out of what He has created, places of shelter in the mountains, garments with which to protect yourselves from the heat and coats of mail to shield you in battle. Thus He completes His favour to you, so that you may submit wholly to Him. 81 But if they turn back, then on you devolves only the clear deliverance (of the message). 82 They recognize the favour of Allah, then they deny it, and most of them are infidels. 83
