The Book of Prayer - Funerals
11/17. Chapter:
The virtue of offering the funeral prayer and following the bier
Sahih Muslim
حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا جَرِيرٌ، - يَعْنِي ابْنَ حَازِمٍ - حَدَّثَنَا نَافِعٌ، قَالَ قِيلَ لاِبْنِ عُمَرَ إِنَّ أَبَا هُرَيْرَةَ يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " مَنْ تَبِعَ جَنَازَةً فَلَهُ قِيرَاطٌ مِنَ الأَجْرِ " . فَقَالَ ابْنُ عُمَرَ أَكْثَرَ عَلَيْنَا أَبُو هُرَيْرَةَ . فَبَعَثَ إِلَى عَائِشَةَ فَسَأَلَهَا فَصَدَّقَتْ أَبَا هُرَيْرَةَ فَقَالَ ابْنُ عُمَرَ لَقَدْ فَرَّطْنَا فِي قَرَارِيطَ كَثِيرَةٍ .
Nafi' narrated that it was said to Ibn 'Umar that Abu Huraira reported to have heard Allah's Messenger (ﷺ) as saying: He who follows the bier, for him is the reward of one qirat. Ibn 'Umar said: Abu Huraira narrated it too often. So he sent (a messenger to) 'A'isha to ascertain (the fact). She ('A'isha) testified Abu Huraira. Ibn 'Umar said: We missed so many qirats.
