Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Muhammad, may Allah have mercy on him, that a person sold a sick camel to another and made a condition regarding its head and skin (i.e., excepted them). The camel recovered, and that person did not slaughter it. Hazrat Shurayh, may Allah have mercy on him, said: He should be given its equivalent. The narrator says that I mentioned this to Hazrat ‘Amir, and he said: Both Hazrat ‘Ali, may Allah be pleased with him, and Hazrat Shurayh, may Allah have mercy on him, gave the verdict of equivalence.
