4114 - وَ رَوَى صَفْوَانُ بْنُ يَحْيَى عَنْ إِسْحَاقَ بْنِ عَمَّارٍ قَالَ : سَأَلْتُ أَبَا إِبْرَاهِيمَ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلرَّجُلِ يَرْهَنُ اَلرَّهْنَ بِمِائَةِ دِرْهَمٍ وَ هُوَ يُسَاوِي ثَلاَثَمِائَةِ دِرْهَمٍ فَيُهْلِكُهُ أَ عَلَى اَلرَّجُلِ أَنْ يَرُدَّ عَلَى صَاحِبِهِ مِائَتَيْ دِرْهَمٍ قَالَ "نَعَمْ لِأَنَّهُ أَخَذَ رَهْناً فِيهِ فَضْلٌ وَ ضَيَّعَهُ" قُلْتُ فَهَلَكَ نِصْفُ اَلرَّهْنِ قَالَ "عَلَى حِسَابِ ذَلِكَ" قُلْتُ فَيَتَرَادَّانِ اَلْفَضْلَ قَالَ "نَعَمْ".
Hadith.4114 - Safwan ibn Yahya narrated from Ishaq ibn Ammar, who said:
I asked Abu Ibrahim (Imam Musa ibn Jafar Al-Kadhim 
) about a man who takes an item as collateral (rahn) for one hundred dirhams, while its value is three hundred dirhams, and it gets destroyed. Is the man required to return two hundred dirhams to its owner?
Imam said: "Yes, because he took collateral that had surplus value and then caused its loss."
I asked: What if half of the collateral is destroyed?
Imam said: "It will be accounted for accordingly."
I asked: Should they return the surplus value between them?
Imam said: "Yes."
