He who offered prayer over the dead, but did not follow the bier, for him is the reward of one qirat, and he who followed it, for him is the reward of two qirats. It was asked what the qirats were. He said: The smaller amongst the two is equivalent to Uhud.
وَحَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا بَهْزٌ، حَدَّثَنَا وُهَيْبٌ، حَدَّثَنِي سُهَيْلٌ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏
"‏ مَنْ صَلَّى عَلَى جَنَازَةٍ وَلَمْ يَتْبَعْهَا فَلَهُ قِيرَاطٌ فَإِنْ تَبِعَهَا فَلَهُ قِيرَاطَانِ ‏"‏ ‏.‏ قِيلَ وَمَا الْقِيرَاطَانِ قَالَ ‏"‏ أَصْغَرُهُمَا مِثْلُ أُحُدٍ ‏"‏ .‏
