Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Amr bin Rashid that a man bought a camel from someone; the camel was sick. The seller made an exception for the camel’s skin. Later, the camel recovered. Both of them took their dispute to Hazrat Umar (may Allah be pleased with him). Hazrat Umar (may Allah be pleased with him) sent them to Hazrat Ali (may Allah be pleased with him). Hazrat Ali (may Allah be pleased with him) said: The price of the camel should be assessed in the market, and he should be given the equivalent of the skin.
