قَالَ مَالِكٌ : فَإِنْ لَمْ تَكُنْ مِمَّنْ تَحِيضُ، فَعِدَّتُهَا ثَلَاثَةُ أَشْهُرٍ .
Imam Malik, may Allah have mercy on him, said: If this umm walad does not menstruate, then she should observe 'iddah for three months.
مَالِكٌ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ، أَنَّهُ كَانَ يَقُولُ : عِدَّةُ أُمِّ الْوَلَدِ، إِذَا تُوُفِّيَ سَيِّدُهَا، حَيْضَةٌ . ¤ قَالَ مَالِكٌ : وَهُوَ الْأَمْرُ عِنْدَنَا . ¤
It is narrated from Qasim bin Muhammad that he used to say: When the master of an umm walad slave-woman dies, her waiting period (‘iddah) is one menstrual cycle.
Imam Malik, may Allah have mercy on him, said: According to us, this is the ruling.
