Allah it is Who hath appointed for you cattle, that ye may ride on some of them, and eat of some - 79 You may also obtain other benefits from them. You may ride them to seek whatever you need or be carried by them as ships carry you by sea. 80 And He shows you His signs; so which sign of Allah will you deny? 81 Did they not journey in the land that they may behold the end of those who had gone before them? They were more numerous and greater in strength and left behind more splendid traces in the land. Yet their attainments did not avail them. 82 For when their messengers came to them with Clear Signs, they exulted in such knowledge (and skill) as they had; but that very (Wrath) at which they were wont to scoff hemmed them in. 83 And when they saw Our Might, they said: 'We believe in Allah alone, and we disbelieve in that we used to associate with Him' 84 But their belief was not going to profit them when they had seen Our punishment; (this is) Allah's law, which has indeed obtained in the matter of His servants, and there the unbelievers are lost. 85
