Sahih al-Bukhari 4717Book 65, Hadith 239
حَدَّثَنِي عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي سَلَمَةَ، وَابْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، رضى الله عنه عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " فَضْلُ صَلاَةِ الْجَمِيعِ عَلَى صَلاَةِ الْوَاحِدِ خَمْسٌ وَعِشْرُونَ دَرَجَةً، وَتَجْتَمِعُ مَلاَئِكَةُ اللَّيْلِ وَمَلاَئِكَةُ النَّهَارِ فِي صَلاَةِ الصُّبْحِ " . يَقُولُ أَبُو هُرَيْرَةَ اقْرَءُوا إِنْ شِئْتُمْ {وَقُرْآنَ الْفَجْرِ إِنَّ قُرْآنَ الْفَجْرِ كَانَ مَشْهُودًا}
Abu Huraira said, "The Prophet (ﷺ) said, 'A prayer performed in congregation is twenty-five times more superior in reward to a prayer performed by a single person. The angels of the night and the angels of the day are assembled at the time of the Fajr (Morning) prayer." Abu Huraira added, "If you wish, you can recite:-- 'Verily! The recitation of the Qur'an in the early dawn (Morning prayer) is ever witnessed (attended by the angels of the day and the night).' (17.78)
