[Machine] That Um Kulthum, the daughter of Ali, and her son Zaid both passed away on the same day. The two widows met each other but could not tell which one of them had died first, so they did not inherit from each other. It is also mentioned that the people of Siffin did not inherit from each other, nor did the people of Harrah.
أَنَّ أُمَّ كُلْثُومٍ بِنْتَ عَلِيٍّ وَابْنَهَا زَيْدًا وَقَعَا فِي يَوْمٍ وَاحِدٍ وَالْتَقَتِ الصَّائِحَتَانِ فَلَمْ يُدْرَ أَيُّهُمَا هَلَكَ قَبْلُ فَلَمْ تَرِثْهُ وَلَمْ يَرِثْهَا وَأَنَّ أَهْلَ صِفِّينَ لَمْ يَتَوَارَثُوا وَأَنَّ أَهْلَ الْحَرَّةِ لَمْ يَتَوَارَثُوا
