He who attends the funeral till the prayer is offered for (the dead), for him is the reward of one qirat, and he who attends (and stays) till he is buried, for him is the reward of two qirats. It was said: What are the qirats? He said: They are equivalent to two huge mountains. Two other narrators added: Ibn 'Umar used to pray and then depart (without waiting for the burial of the dead). When the tradition of Abu Huraira reached him, he said:" We have lost many qirats." (Using translation from Muslim 945a)
قَالَ رَسُولُ اللهِ ﷺ مَنْ شَهِدَ الْجِنَازَةَ حَتَّى يُصَلِّيَ عَلَيْهَا فَلَهُ قِيرَاطٌ وَمَنْ شَهِدَهَا حَتَّى تُدْفَنَ كَانَ لَهُ قِيرَاطَانِ وَقِيلَ وَمَا الْقِيرَاطَانِ؟ قَالَ مِثْلُ الْجَبَلَيْنِ الْعَظِيمَيْنِ انْتَهَى حَدِيثُ شَبِيبٍ زَادَ ابْنَ وَهْبٍ فِي رِوَايَتِهِ عَنْ يُونُسَ قَالَ ابْنُ شِهَابٍ قَالَ سَالِمُ بْنُ عَبْدِ اللهِ بْنِ عَمْرٍو كَانَ ابْنُ عُمَرَ يُصَلِّي عَلَيْهَا ثُمَّ يَنْصَرِفُ فَلَمَّا بَلَغَهُ حَدِيثُ أَبِي هُرَيْرَةَ قَالَ لَقَدْ ضَيَّعْنَا قَرَارِيطَ كَثِيرَةً
