Musannaf Ibn Abi Shayba 19:631

Abu Bakr narrated to us, he said: Muhammad ibn Yazid narrated to us, from Abu al-Ala, from Qatadah, from Ikrimah, from Ibn Abbas regarding two men, one of whom sold the other: He said: The sale is annulled, and they are both punished, and there is no cutting (of the hand) for them.
