4044 - وَ رَوَى صَفْوَانُ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ قَالَ : سَأَلْتُ أَبَا إِبْرَاهِيمَ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلرَّجُلِ يَكُونُ لِي عَلَيْهِ اَلْمَالُ فَيَقْضِينِي بَعْضاً دَنَانِيرَ وَ بَعْضاً دَرَاهِمَ فَإِذَا جَاءَ يُحَاسِبُنِي لِيُوَفِّيَنِي جَاءَ وَ قَدْ تَغَيَّرَ سِعْرُ اَلدَّنَانِيرِ أَيَّ اَلسِّعْرَيْنِ أَحْسُبُ اَلَّذِي كَانَ يَوْمَ أَعْطَانِي اَلدَّنَانِيرَ أَوْ سِعْرَ يَوْمَ أُحَاسِبُهُ قَالَ "سِعْرَ يَوْمَ أَعْطَاكَ اَلدَّنَانِيرَ لِأَنَّكَ حَبَسْتَ مَنْفَعَتَهَا عَنْهُ".
Hadith.4044 - Safwan narrated from Ishaq ibn Ammar, who said:
I asked Abu Ibrahim (Imam Musa ibn Jafar Al-Kadhim 
) about a man who owes me money and repays me partially with dinars and partially with dirhams. When he comes to settle the remaining amount, the price of the dinars has changed.
I asked: "Which price should I calculate, the price on the day he gave me the dinars or the price on the day we settle the account?"
Imam said: "The price on the day he gave you the dinars, because you withheld their benefit from him."
