It is God who [at all times works wonders for you: thus, He] provides for you [all manner of] livestock, so that on some of them you may ride, and from some derive your food, 79 There are advantages for you in them, so that you may satisfy your needs through them, and may be borne upon them and on ships. 80 And He shows you His signs; so which sign of Allah will you deny? 81 Do they not travel through the earth and see what was the End of those before them? They were more numerous than these and superior in strength and in the traces (they have left) in the land: Yet all that they accomplished was of no profit to 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 Then, when they saw Our doom, they said: We believe in Allah only and reject (all) 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
