Musannaf Ibn Abi Shayba 13:539

Abu Bakr narrated to us, he said: Waki’ narrated to us, he said: Hasan ibn Salih narrated to us, from Zuhayr al-Absi, that a man hired a man to work on a camel, so he struck him and gouged out his eye. He disputed with him before Shurayh, so he held him liable and said: "He only hired you to improve, and he did not hire you to corrupt."
