Musannaf Ibn Abi Shayba 13:3351

Abu Bakr narrated to us, he said: Hafs narrated to us, from Ash'ath, from Bukayr al-Dakhma, from Yunus, from al-Hasan, and Mughirah, from Ibrahim, that they both disliked that a man gives an animal, or a servant, or a house, and says: "Whatever you earn from anything, it is between me and you."
