Musannaf Ibn Abi Shaybah 23429 — Those who said: Muslims are bound

It is narrated from Amr bin Rashid that a man bought a camel from someone while the camel was sick, and the seller excepted the camel's hide from the sale. Later the camel recovered. The two of them took their dispute to Sayyiduna Umar (may Allah be pleased with him), and Sayyiduna Umar (may Allah be pleased with him) sent them to Sayyiduna Ali (may Allah be pleased with him). Sayyiduna Ali (may Allah be pleased with him) said: "The camel shall be valued in the market, and he shall be given the equivalent of the hide."
