Musannaf Ibn Abi Shayba 13:3186

Abu Bakr narrated to us, he said: Ibn ‘Uyaynah narrated to us, from Ayyub, from Muhammad, that a man sold a slave of his for the price of his hair—a bundle. He disputed [the matter] before Shurayh, who said: "You concealed the defect and hid it." So he did not permit it, and he returned him.
