Sahih al-Bukhari 6515

It is related that 'A'isha, the wife of the Prophet, may Allah bless him and grant him peace, said, " 'Utba ibn Abi Waqqas had made his brother, Sa'd ibn Abi Waqqas give an undertaking, saying, 'The son of the slavegirl of Zam'a is mine, so take him to you.' In the year of the Conquest, Sa'd took him and said, 'My brother's son who gave me an undertaking about him.' 'Abd ibn Zam'a went to him and said, 'My brother and the son of my father's slavegirl. He was born on his bed.' They took the matter to the Messenger of Allah, may Allah bless him and grant him peace. Sa'd said, 'Messenger of Allah, the son of my brother. He gave me an undertaking about him.' 'Abd ibn Zam'a said, 'My brother and the son of my father's slavegirl.' The Messenger of Allah, may Allah bless him and grant him peace, said, 'He is yours, 'Abd ibn Zam'a.' Then the Messenger of Allah, may Allah bless him and grant him peace, said, 'The child belongs to the bed and stones belong to the adulterer.' Then he said to Sawda bint Zam'a, 'Veil yourself from him,' since he saw that he resembled 'Utba. He did not see her until he died." XXX. Judgement about wells and the like
