Musannaf Ibn Abi Shayba 13:867

Abu Bakr narrated to us, he said: Abu Mu'awiyah narrated to us, from al-A'mash, from Hassan Abu al-Ashras, from Shurayh: A man came to him and said: "This man sold me a slave girl with a twisted neck." Shurayh said: "Your evidence that he sold her to you in that condition, otherwise his oath by Allah that he did not sell her to you in that condition."
