The Prophet (ﷺ) said, "The boy is for the owner of the bed."
Sahih al-Bukhari Book 85, Hadith 27
← Previous Hadith `Utba (bin Abi Waqqas) said to his brother Sa`d, "The son of the slave girl of Zam`a is my son, so be his custodian." So when it was the year of the Conquest of Mecca, Sa`d took that child and said, "He is my nephew, and my brother told me to be his custodian." On that, 'Abu bin Zam`a got up and said, 'but the child is my brother, and the son of my father's slave girl as he was born on his bed." So they both went to the Prophet. Sa`d said, "O Allah's Messenger (ﷺ)! (This is) the son of my brother and he told me to be his custodian." Then 'Abu bin Zam`a said, "(But he is) my brother and the son of the slave girl of my father, born on his bed." The Prophet (ﷺ) said, "This child is for you. O 'Abu bin Zam`a, as the child is for the owner of the bed, and the adulterer receives the stones." He then ordered (his wife) Sauda bint Zam`a to cover herself before that boy as he noticed the boy's resemblance to `Utba. Since then the boy had never seen Sauda till he died.

Sahih al-Bukhari Book 85, Hadith 26 Next Hadith → I bought Barira (a female slave). The Prophet (ﷺ) said (to me), "Buy her as the Wala' is for the manumitted." Once she was given a sheep (in charity). The Prophet (ﷺ) said, "It (the sheep) is a charitable gift for her (Barira) and a gift for us." Al-Hakam said, "Barira's husband was a free man." Ibn `Abbas said, 'When I saw him, he was a slave."
