Chapter 43 | The Reward for Walking in a Funeral Procession
5ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنِ ابْنِ أَبِي نَجْرَانَ عَنْ عَاصِمِ بْنِ حُمَيْدٍ عَنْ أَبِي بَصِيرٍ قَالَ سَمِعْتُ أَبَا جَعْفَرٍ (عَلَيْهِ الْسَّلام) يَقُولُ مَنْ مَشَى مَعَ جَنَازَةٍ حَتَّى يُصَلَّى عَلَيْهَا ثُمَّ رَجَعَ كَانَ لَهُ قِيرَاطٌ مِنَ الأجْرِ فَإِذَا مَشَى مَعَهَا حَتَّى تُدْفَنَ كَانَ لَهُ قِيرَاطَانِ وَالْقِيرَاطُ مِثْلُ جَبَلِ أُحُدٍ.
5. A number of our people have narrated from Sahl ibn Ziyad from ibn abu Najran from ‘Asem ibn Hamid from abu Basir who has said the following: “I heard abu Ja‘far , say, ‘If one walks in the procession for the burial of a deceased until Salah (prayer) for a deceased is complete and then returns back, his reward is one qirat. If one walks until burial is complete, his reward is two qirat and one qirat is of the size of the mountain of ’Uhud.’”
