وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ، وَسَالِمِ بْنِ عَبْدِ اللَّهِ، وَأَبِي، بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ وَسُلَيْمَانَ بْنِ يَسَارٍ وَابْنِ شِهَابٍ أَنَّهُمْ كَانُوا يَقُولُونَ إِذَا دَخَلَتِ الْمُطَلَّقَةُ فِي الدَّمِ مِنَ الْحَيْضَةِ الثَّالِثَةِ فَقَدْ بَانَتْ مِنْ زَوْجِهَا وَلاَ مِيرَاثَ بَيْنَهُمَا وَلاَ رَجْعَةَ لَهُ عَلَيْهَا ‏.‏

Yahya related to me from Malik that he had heard that Abu Bakribn Abd ar-Rahman and Sulayman ibn Yasar and Ibn Shihab used to say,"When the divorced woman enters the beginning of her third period, sheis clearly separated from her husband and there is no inheritancebetween them and he has no access to her."
