Muwatta Malik 1214

These are the words of a Companion, not of the Prophet ﷺ. The chain is graded on its own terms.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، وَزَيْدِ بْنِ أَسْلَمَ، عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، أَنَّ الأَحْوَصَ، هَلَكَ بِالشَّامِ حِينَ دَخَلَتِ امْرَأَتُهُ فِي الدَّمِ مِنَ الْحَيْضَةِ الثَّالِثَةِ وَقَدْ كَانَ طَلَّقَهَا فَكَتَبَ مُعَاوِيَةُ بْنُ أَبِي سُفْيَانَ إِلَى زَيْدِ بْنِ ثَابِتٍ يَسْأَلُهُ عَنْ ذَلِكَ فَكَتَبَ إِلَيْهِ زَيْدٌ إِنَّهَا إِذَا دَخَلَتْ فِي الدَّمِ مِنَ الْحَيْضَةِ الثَّالِثَةِ فَقَدْ بَرِئَتْ مِنْهُ وَبَرِئَ مِنْهَا وَلاَ تَرِثُهُ وَلاَ يَرِثُهَا ‏.‏

Yahya related to me from Malik from Nafi and Zayd ibn Aslam from Sulayman ibn Yasar that al-Ahwas died in Syria when his wife had begun her third menstrual period after he had divorced her. Muawiya ibn Abi Sufyan wrote and asked Zayd ibn Thabit about that. Zayd wrote to him, "When she began her third period, she was free from him and he was free from her, and he does not inherit from her nor she from him
