It is God who provides livestock for you, some for riding and some for your food: 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: which then of Allah's signs will you deny? 81 Have they not travelled in the earth so that they may behold what wise hath been the end of those before them. They were more numerous than these, and mightier in strength and the traces in the land. But naught availed them of that which they had been earning. 82 So when their Noble Messengers came to them with clear signs, they remained happy over the worldly knowledge they possessed, and upon them only reverted what they used to mock at! 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
