3- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ مُحَمَّدِ بْنِ أَبِي حَمْزَةَ وَحُسَيْنِ بْنِ عُثْمَانَ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) فِي رَجُلٍ مَاتَ فَأَقَرَّ عَلَيْهِ بَعْضُ وَرَثَتِهِ لِرَجُلٍ بِدَيْنٍ قَالَ يَلْزَمُهُ ذَلِكَ فِي حِصَّتِهِ.

3. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from Muhammad ibn abu Hamzah and Husayn ibn ‘Uthman from Ishaq ibn ‘Ammar who has narrated the following: “About the case of a man who dies and a certain one of his heir confirms his owing a certain amount. He (the Imam) said, ‘It become binding and applicable to his share in the legacy.’”
