١٩ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ إِسْمَاعِيلَ بْنِ بَزِيعٍ عَنْ حَنَانِ بْنِ سَدِيرٍ عَنْ أَبِيهِ قَالَ قُلْتُ لأبِي جَعْفَرٍ (عَلَيهِ السَّلام) هَلْ يَجْزِي الْوَلَدُ وَالِدَهُ فَقَالَ لَيْسَ لَهُ جَزَاءٌ إِلا فِي خَصْلَتَيْنِ يَكُونُ الْوَالِدُ مَمْلُوكاً فَيَشْتَرِيهِ ابْنُهُ فَيُعْتِقُهُ أَوْ يَكُونُ عَلَيْهِ دَيْنٌ فَيَقْضِيهِ عَنْهُ.
19. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn Isma’il ibn Bazi’ from Hannan ibn Sadir from his father who has said the following: “I asked abu Ja’far  ‘Can a son pay back (for the favors of) a father?’ The Imam said, ‘There is no payment for him except two things: if the father is a slave and the son buys him and sets him free, or the father is in debt and the son pays it off.’”
