The Book of Prayer - Funerals
The virtue of offering the funeral prayer and following the bier
حَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ يَزِيدَ بْنِ كَيْسَانَ، حَدَّثَنِي أَبُو حَازِمٍ عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " مَنْ صَلَّى عَلَى جَنَازَةٍ فَلَهُ قِيرَاطٌ وَمَنِ اتَّبَعَهَا حَتَّى تُوضَعَ فِي الْقَبْرِ فَقِيرَاطَانِ " . قَالَ قُلْتُ يَا أَبَا هُرَيْرَةَ وَمَا الْقِيرَاطُ قَالَ " مِثْلُ أُحُدٍ " .
Abu Huraira reported Allah's Messenger (ﷺ) as saying: He who offers prayer for the dead, for him is (the reward of) one qirat; and he who follows the bier till it is placed in the grave, for him (is the reward of) two qirats. I (Abu Hazim, one of the narrators) said: Abu Huraira, what is a qirat? He said: It is like the hill of Uhud.
