وَعَنْهُ قَالَ: قَالَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -«مَنْ شَهِدَ اَلْجِنَازَةَ حَتَّى يُصَلَّى عَلَيْهَا فَلَهُ قِيرَاطٌ، وَمَنْ شَهِدَهَا حَتَّى تُدْفَنَ فَلَهُ قِيرَاطَانِ». قِيلَ: وَمَا اَلْقِيرَاطَانِ? قَالَ: «مِثْلُ اَلْجَبَلَيْنِ اَلْعَظِيمَيْنِ»
“Whoever accompanies the funeral (the dead body) until he performs the funeral prayer will have a reward equal to (one Qirat), and whoever accompanies the burial procession, will be doubly awarded (two Qirat).” They then asked, ‘What is meant by the two Qirat?’ He replied (sallallahu alayhi wa sallam) “Like two huge mountains.” Agreed upon. Muslim added the statement, ‘until it is buried.’
