And Allah's is the Unseen of the heavens and the earth, and the affair of the Hour will be not but as a flash of the eye, or it is even nearer, verily Allah is over everything Potent. 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 Have you not considered the free movements of the birds high in the sky above? What keeps them aloft except God? In this there is evidence (of the truth) for the believing people. 79 God has made your house the place for you to rest. He has also made homes for you out of the skins of cattle which are easy to carry along on a journey or at a camp. He has made wool, fur and the hair of cattle a temporary means of enjoyment for you. 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 But if they turn away, thy duty is only to preach the clear Message. 82 They are aware of the favours of Allah, and yet refuse to acknowledge them. Most of them are determined not to accept the Truth. 83
