Yahya related to me from Malik from Ibn Shihab from Abu Abd ar- Rahman that Zayd ibn Thabit said that if a man divorced his slave-girl three times and then bought her, she was not halal for him until she had married another husband.
Muwatta Malik Book 28, Hadith 32
← Previous Hadith Yahya related to me from Malik from Yahya ibn Said that Said ibn al-Musayyab said, "The slave girl is not married when there is a free woman who is a wife unless the free woman wishes it. If the free woman complies, she has two-thirds of the division of time."

Malik said, "A free man must not marry a slave-girl when he can afford to marry a free-woman, and he should not marry a slave-girl when he cannot afford a free woman unless he fears fornication. That is because Allah, may he be Blessed and Exalted, says in His Book, 'If you are not affluent enough to marry believing women, who are muhsanat, take slave-girls who are believing women that your right hands own.' (Sura 4 ayat 24) He says, 'That is for those of you who fear al-anat.' "

Malik said, "Al-anat is fornication."

Muwatta Malik Book 28, Hadith 31 Next Hadith → Yahya related to me from Malik that he had heard that Said ibn al-Musayyab and Sulayman ibn Yasar were asked whether, when a man married a slave of his to a slave-girl and the slave divorced her irrevocably, and then her master gave her to the slave, she was then halal for the slave by the possession of the right hand. They said, "No. She is not halal until she has married another husband."
