It was narrated from Abu Hurairah that the Prophet said: “Whoever offers the funeral prayer will have one Qirat and whoever awaits until (the burial) is finished will have two Qirat.” They said: ‘What are these two Qirat?’ He said: ‘Like two mountains.’”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ الأَعْلَى، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ قَالَ " مَنْ صَلَّى عَلَى جِنَازَةٍ فَلَهُ قِيرَاطٌ وَمَنِ انْتَظَرَ حَتَّى يُفْرَغَ مِنْهَا فَلَهُ قِيرَاطَانِ " . قَالُوا وَمَا الْقِيرَاطَانِ قَالَ " مِثْلُ الْجَبَلَيْنِ " .
