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 And He showeth you His tokens. Which, then, of the tokens of Allah do ye deny? 81 What, have they not journeyed in the land and beheld how was the end of those before them? They were stronger than themselves in might and left firmer traces in the earth; yet that they earned did not avail them. 82 And when their messengers came to them with clear proofs, they [merely] rejoiced in what they had of knowledge, but they were enveloped by what they used to ridicule. 83 So that when they saw Our might, they said: "We believe in God the one and single, and reject those we associated (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
