4115 - وَ رَوَى مُحَمَّدُ بْنُ قَيْسٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ : "قَضَى أَمِيرُ اَلْمُؤْمِنِينَ عَلَيْهِ اَلسَّلاَمُ فِي اَلرَّهْنِ إِذَا كَانَ أَكْثَرَ مِنْ مَالِ اَلْمُرْتَهِنِ فَهَلَكَ أَنْ يُؤَدَّى اَلْفَضْلُ إِلَى صَاحِبِ اَلرَّهْنِ وَ إِنْ كَانَ اَلرَّهْنُ أَقَلَّ مِنْ مَالِهِ فَهَلَكَ اَلرَّهْنُ أَدَّى إِلَيْهِ صَاحِبُهُ فَضْلَ مَالِهِ وَ إِنْ كَانَ اَلرَّهْنُ يَسْوَى مَا رَهَنَهُ فَلَيْسَ عَلَيْهِ شَيْءٌ ".
Hadith.4115 - Muhammad ibn Qays narrated from Abu Ja'far Imam Muhammad ibn Ali Al-Baqir 
:
"Commander of the Faithful ruled regarding collateral (rahn) that if its value is greater than the debt owed to the creditor and it is destroyed, the excess value must be returned to the owner of the collateral.
And if the collateral is worth less than the debt and is destroyed, the debtor must pay the remaining amount owed to the creditor.
But if the value of the collateral equals the debt, then there is no further obligation on either party."
