Narrated by:Abu Hurairah said
It was narrated that Abu Hurairah said:"The Messenger of Allah said: 'Whoever offers the funeral prayer will have one Qirat and whoever stays until )the body) is placed in the Lahd will have two Qirats, and the two Qirats are like two great mountains."'
أَخْبَرَنَا نُوحُ بْنُ حَبِيبٍ، قَالَ أَنْبَأَنَا عَبْدُ الرَّزَّاقِ، قَالَ أَنْبَأَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ صَلَّى عَلَى جَنَازَةٍ فَلَهُ قِيرَاطٌ وَمَنِ انْتَظَرَهَا حَتَّى تُوضَعَ فِي اللَّحْدِ فَلَهُ قِيرَاطَانِ وَالْقِيرَاطَانِ مِثْلُ الْجَبَلَيْنِ الْعَظِيمَيْنِ " .
