Sunan Ibn Majah, Book 6, Hadith 1608 (In-Book) ⓘ
It was narrated from Ubayy bin Ka’b that the Messenger of Allah said: ‘Whoever offers the funeral prayer will have one Qirat; and whoever attends until the burial is over, will have two Qirat. By the One in Whose Hand is the soul of Muhammad! The Qirat is greater than this (mountain of) Uhud.”
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ سَعِيدٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ الْمُحَارِبِيُّ، عَنْ حَجَّاجِ بْنِ أَرْطَاةَ، عَنْ عَدِيِّ بْنِ ثَابِتٍ، عَنْ زِرِّ بْنِ حُبَيْشٍ، عَنْ أُبَىِّ بْنِ كَعْبٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَنْ صَلَّى عَلَى جِنَازَةٍ فَلَهُ قِيرَاطٌ وَمَنْ شَهِدَهَا حَتَّى تُدْفَنَ فَلَهُ قِيرَاطَانِ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ الْقِيرَاطُ أَعْظَمُ مِنْ أُحُدٍ هَذَا " .
