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 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 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 And it is Allah who has given you houses in which to rest, and from the hides of cattle homes so they are light for you on the day you travel and on the day of settling; while from their wool, fur, and hair (He has given you) furnishing and enjoyment for a while. 80 God has given you of things created, shade, and places of shelter in the mountains, and clothes for protection against the heat, and coats (of mail) for defence during war. He thus bestows His favours on you so that you may be grateful to Him. 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
