It is God who appointed for you the cattle, some of them to ride and of some you eat; 79 you have other benefits in them too. You can reach any destination you wish on them: they carry you by land, as ships carry you on the sea. 80 He shows you His signs. Now which of the signs of Allah do you disbelieve? 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 They were far too content with their own knowledge (to pay attention to the Messengers) when Our Messengers came to them with illustrious evidence. They were encompassed by the torment for mocking Our guidance. 83 So when they saw Our punishment, they said: "We believe in Allah Alone and reject (all) that we used to associate with Him as (His) partners. 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
