حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْحَارِثِ، عَنْ عَلِيٍّ
رَضِيَ اللَّهُ عَنْهُ قَضَى مُحَمَّدٌ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: أَنَّ الدَّيْنَ قَبْلَ الْوَصِيَّةِ وَأَنْتُمْ تَقْرَءُونَ الْوَصِيَّةَ قَبْلَ الدَّيْنِ وَأَنَّ أَعْيَانَ بَنِي الْأُمِّ يَتَوَارَثُونَ دُونَ بَنِي الْعَلَّاتِ
Muhammad (sallallahu alayhi wa sallam) ruled that debts must be paid before carrying art bequests, but you read the will before debts are paid off. that sons from the same mother inherit from one another, but sons from different mothers do not.
