The texts
١٣٧٣ - مَسْأَلَةٌ: وَلَا ضَمَانَ عَلَى الْعَامِلِ فِيمَا تَلِفَ مِنْ الْمَالِ - وَلَوْ تَلِفَ كُلُّهُ - وَلَا فِيمَا خَسِرَ فِيهِ، وَلَا شَيْءَ لَهُ عَلَى رَبِّ الْمَالِ، إلَّا أَنْ يَتَعَدَّى أَوْ يُضَيِّعَ فَيَضْمَنُ، لِقَوْلِ رَسُولِ اللَّهِ - صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ - «إنَّ دِمَاءَكُمْ وَأَمْوَالَكُمْ عَلَيْكُمْ حَرَامٌ» . [مَسْأَلَةٌ رَبّ الْمَال وَعَامِل الْقِرَاض أَيُّهُمَا أَرَادَ تَرْكَ الْعَمَلِ فَلَهُ ذَلِكَ]
