4ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ سِنَانٍ عَنْ أَبِي الْجَارُودِ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ الْسَّلام) قَالَ كَانَ فِيمَا نَاجَى الله بِهِ مُوسَى قَالَ يَا رَبِّ مَا لِمَنْ غَسَّلَ الْمَوْتَى فَقَالَ أَغْسِلُهُ مِنْ ذُنُوبِهِ كَمَا وَلَدَتْهُ أُمُّهُ.
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Sinan from abu al-Jarud who has said the following: “Abu Ja‘far (a.s.), has said, ‘One of the matters that Moses spoke about before Allah was this, “O Allah, what is the reward for one who washes a dead body?” The answer was, “I wash his sins as if his mother has just given him birth.’””
