Malik related to me from Hilal ibn Usama from Ata ibn Yasar that Umar ibn al-Hakam said, "I went to the Messenger of Allah, may Allah bless him and grant him peace, and said, 'Messenger of Allah, a slave girl of mine was tending my sheep. I came to her and one of the sheep was lost. I asked her about it and she said that a wolf had eaten it, so I became angry and I am one of the children of Adam, so I struck her on the face. As it happens, I have to set a slave free, shall I free her?' The Messenger of Allah, may Allah bless him and grant him peace, questioned her, 'Where is Allah?' She said, 'In heaven.' He said, 'Who am I?' She said, 'You are the Messenger of Allah.' The Messenger of Allah, may Allah bless him and grant him peace, said, 'Free her.' "
Muwatta Malik Book 38, Hadith 9
← Previous Hadith Malik related to me that he had heard that a slave-girl came to Umar ibn al-Khattab (who had been beaten by her master with a red hot iron) and he set her free.

Malik said, "The generally agreed- on way of doing things among us is that a man is not permitted to be freed while he has a debt against him which exceeds his property. A boy is not allowed to be set free until he has reached puberty. The young person whose affairs are managed cannot set free in his property, even when he reaches puberty, until he manages his property."

Muwatta Malik Book 38, Hadith 8 Next Hadith → Malik related to me from Ibn Shihab from Ubaydullah ibn Abdullah ibn Utba ibn Masud that one of the Ansar came to the Messenger of Allah, may Allah bless him and grant him peace, with a black slave- girl of his. He said, "Messenger of Allah, I must set a slave free who is a mumina. If you think that she is mumina, I will free her." The Messenger of Allah, may Allah bless him and grant him peace, questioned her, "Do you testify that there is no god but Allah?" She said, "Yes." "Do you testify that Muhammad is the Messenger of Allah?" She said, "Yes." "Are you certain about the rising after death?" She said, "Yes." The Messenger of Allah, may Allah bless him and grant him peace, said, "Free her."
