Chapter 109 | Security Deposit ( Al-Rahn ) Mortgage
6- مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ صَفْوَانَ عَنِ ابْنِ بُكَيْرٍ قَالَ سَأَلْتُ أَبَا عَبْدِ اللهِ عَنِ الرَّهْنِ فَقَالَ إِنْ كَانَ أَكْثَرَ مِنْ مَالِ الْمُرْتَهِنِ فَهَلَكَ أَنْ يُؤَدِّيَ الْفَضْلَ إِلَى صَاحِبِ الرَّهْنِ وَإِنْ كَانَ أَقَلَّ مِنْ مَالِهِ فَهَلَكَ الرَّهْنُ أَدَّى إِلَيْهِ صَاحِبُهُ فَضْلَ مَالِهِ وَإِنْ كَانَ الرَّهْنُ سَوَاءً فَلَيْسَ عَلَيْهِ شَيْءٌ.
6. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Safwan from ibn Bukayr who has said the following: “This is concerning my question before abu ‘Abd Allah , about al-Rahn (security deposit). He (the Imam) said, ‘If it is more than what mortgagee has provided and it is destroyed, the difference must be paid to the mortgager; but if it is less and is destroyed, the one who has the extra must pay the difference to the mortgagor, and if both sides are equal then there is nothing to dispute about.’”
