٢- أَحْمَدُ بْنُ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ عَلِيٍّ عَنْ مُحَمَّدِ بْنِ الْفُضَيْلِ عَنْ أَبِي حَمْزَةَ قَالَ سَأَلْتُ أَبَا جَعْفَرٍ (عَلَيْهِ السَّلام) عَنْ رَجُلٍ كَانَ لَهُ عَلَى رَجُلٍ دَيْنٌ فَجَاءَهُ رَجُلٌ فَاشْتَرَاهُ مِنْهُ [بِعَرْضٍ] ثُمَّ انْطَلَقَ إِلَى الَّذِي عَلَيْهِ الدَّيْنُ فَقَالَ لَهُ أَعْطِنِي مَا لِفُلانٍ عَلَيْكَ فَإِنِّي قَدِ اشْتَرَيْتُهُ مِنْهُ كَيْفَ يَكُونُ الْقَضَاءُ فِي ذَلِكَ فَقَالَ أَبُو جَعْفَرٍ (عَلَيْهِ السَّلام) يَرُدُّ عَلَيْهِ الرَّجُلُ الَّذِي عَلَيْهِ الدَّيْنُ مَالَهُ الَّذِي اشْتَرَاهُ بِهِ مِنَ الرَّجُلِ الَّذِي لَهُ الدَّيْنُ.
2. Ahmad ibn Muhammad has narrated from al-Hassan ibn Ali from Muhammad ibn al-Fudayl from abu Hamzah who has said the following: “I once asked abu Ja’far , about the case of a man to whom another person owes a loan and a third person buys the loan from the creditor to collect it from the debtor. The collector demands the debtor for payment; and (what is the Imam’s) judgment in this issue. Abu Ja’far , made a pronouncement that said, The debtor can pay to the collector what he (the collector) has paid to the creditor.’”
