Musannaf Ibn Abi Shayba 35:17

Ibn ‘Uyaynah narrated to us, from al-Zuhri, from Humayd ibn ‘Abd al-Rahman, and from Muhammad ibn al-Nu‘man, from his father, that his father gifted a slave to him. He came to the Prophet, may Allah bless him and grant him peace, to have him bear witness to it. He said, "Have you gifted all of your children the like of this?" He said, "No." He said, "Then take it back."
