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 hath brought you forth from the bellies of your mothers while ye know not aught, and He hath appointed for you hearing and sight and hearts that haply ye might give thanks. 78 Do they not see the birds held poised in the vault of heaven? Nothing holds them up except God. Truly, 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 made for you, from that which He has created, shadows and has made for you from the mountains, shelters and has made for you garments which protect you from the heat and garments which protect you from your [enemy in] battle. Thus does He complete His favor upon you that you might submit [to Him]. 81 But if they turn away, thy duty is only to preach the clear Message. 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
