Hadith 1207Q4

قَالَ مَالِكٌ : فِي الرَّجُلِ تَكُونُ تَحْتَهُ الْأَمَةُ، ثُمَّ يَبْتَاعُهَا فَيَعْتِقُهَا، إِنَّهَا تَعْتَدُّ عِدَّةَ الْأَمَةِ حَيْضَتَيْنِ، مَا لَمْ يُصِبْهَا، فَإِنْ أَصَابَهَا بَعْدَ مِلْكِهِ إِيَّاهَا قَبْلَ عِتَاقِهَا، لَمْ يَكُنْ عَلَيْهَا إِلَّا الِاسْتِبْرَاءُ بِحَيْضَةٍ.
Imam Malik, may Allah have mercy on him, said that if a slave girl is in someone's marriage, then the husband buys her and sets her free, she should observe the waiting period of two menstruations if he did not have intercourse with her after buying her; otherwise, one menstruation for istibra is sufficient.
