Chapter 43 | The Reward for Walking in a Funeral Procession
4ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ سَيْفِ بْنِ عَمِيرَةَ عَنْ عَمْرِو بْنِ شِمْرٍ عَنْ جَابِرٍ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ الْسَّلام) قَالَ مَنْ شَيَّعَ مَيِّتاً حَتَّى يُصَلِّيَ عَلَيْهِ كَانَ لَهُ قِيرَاطٌ مِنَ الأجْرِ وَمَنْ بَلَغَ مَعَهُ إِلَى قَبْرِهِ حَتَّى يُدْفَنَ كَانَ لَهُ قِيرَاطَانِ مِنَ الأجْرِ وَالْقِيرَاطُ مِثْلُ جَبَلِ أُحُدٍ.
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Sayf ibn ‘Amirah from ‘Amr ibn Shimr from Jabir who has said the following: “Abu Ja’far , has said, ‘If one escorts a deceased until the Salah (prayer) for a deceased is performed, his reward is one qirat and one who escorts the deceased up to the grave and until burial is complete, his reward is two qirat; and one qirat is of the size of the mountain of ‘Uhud.”
