Musannaf Ibn Abi Shayba 13:1157

Abu Bakr narrated to us, he said: Waki’ narrated to us, from Isra’il, from Jabir, from ‘Amir and al-Hakam, regarding a man who sold a slave girl, then discovered a defect in her, so he placed her in the hands of a neutral party, and she died. They both said: She is from the property of the seller.
