Musannaf Ibn Abi Shayba 25:275

Ibn ‘Ulayyah 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 him a slave. He came to the Prophet, may Allah bless him and grant him peace, to have him bear witness to it. He said, "Have you given all of your children the like of this?" He said, "No." He said, "Then take it back."
