Jami` at-Tirmidhi, Volume 2, Book 8, Hadith 1040 (DarusSalam) ⓘ
Abu Hurairah narrated that: The Messenger of Allah said: "Whoever performs the funeral prayer then he will get a reward equal to a Qirat. Whoever follows it until it is buried then he will get a reward equal to two Qirat, one of them, or the least of them, is similar to Uhud (mountain)." This was mentioned to Ibn Umar, so he sent a message to Aishah to ask her about that, and she said: "Abu Hurairah has told the truth." So Ibn Umar said: "We have missed many Qirat."
حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا عَبْدَةُ بْنُ سُلَيْمَانَ، عَنْ مُحَمَّدِ بْنِ عَمْرٍو، حَدَّثَنَا أَبُو سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ صَلَّى عَلَى جَنَازَةٍ فَلَهُ قِيرَاطٌ وَمَنْ تَبِعَهَا حَتَّى يُقْضَى دَفْنُهَا فَلَهُ قِيرَاطَانِ أَحَدُهُمَا أَوْ أَصْغَرُهُمَا مِثْلُ أُحُدٍ " . فَذَكَرْتُ ذَلِكَ لاِبْنِ عُمَرَ فَأَرْسَلَ إِلَى عَائِشَةَ فَسَأَلَهَا عَنْ ذَلِكَ فَقَالَتْ صَدَقَ أَبُو هُرَيْرَةَ . فَقَالَ ابْنُ عُمَرَ لَقَدْ فَرَّطْنَا فِي قَرَارِيطَ كَثِيرَةٍ . وَفِي الْبَابِ عَنِ الْبَرَاءِ وَعَبْدِ اللَّهِ بْنِ مُغَفَّلٍ وَعَبْدِ اللَّهِ بْنِ مَسْعُودٍ وَأَبِي سَعِيدٍ وَأُبَىِّ بْنِ كَعْبٍ وَابْنِ عُمَرَ وَثَوْبَانَ . قَالَ أَبُو عِيسَى حَدِيثُ أَبِي هُرَيْرَةَ حَدِيثٌ حَسَنٌ صَحِيحٌ . قَدْ رُوِيَ عَنْهُ مِنْ غَيْرِ وَجْهٍ .
