Free man

Bukhari :: Book 3 :: Volume 47 :: Hadith 752 Narrated 'Aisha:
I intended to buy Buraira but her masters stipulated that her Wala should be for them. When the Prophet was told about it, he said to me, "Buy and manumit her, as the Wala' is for the liberator." Once Buraira was given some meat, and the Prophet asked, "What is this?" I said, "It has been given to Buraira in charity." He said, "It is sadaqa for her but a gift for us." Buraira was given the option (to stay with her husband or to part with him). AbdurRahman (a sub-narrator) wondered, "Was her husband a slave or a free man?" Shu'ba (another sub-narrator) said, "I asked 'Abdur-Rahman whether her husband was a slave or a free man. He replied that he did not know whether he was a slave or a free man."

Bukhari :: Book 3 :: Volume 47 :: Hadith 753 Narrated Um 'Atiyya:
Once the Prophet went to 'Aisha and asked her whether she had something (to eat). She said that she had nothing except the mutton which Um 'Atiyya had sent to (Buraira) in charity. The Prophet said that it had reached its destination (i.e. it is no longer an object of charity.)
