Abu Huraira reported Allah's Apostle (ﷺ) as saying:Prayer said in a congregation is twenty-five degrees more excellent than prayer said by a single person. He (Abu Huraira further) said: The angels of the night and the angels of the day meet together. Abu Huraira said: Recite it you like:" Surely the recital of the Qur'an at dawn is witnessed" (al-Qur'an, xvii. 78).
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ الأَعْلَى، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " تَفْضُلُ صَلاَةٌ فِي الْجَمِيعِ عَلَى صَلاَةِ الرَّجُلِ وَحْدَهُ خَمْسًا وَعِشْرِينَ دَرَجَةً " . قَالَ " وَتَجْتَمِعُ مَلاَئِكَةُ اللَّيْلِ وَمَلاَئِكَةُ النَّهَارِ فِي صَلاَةِ الْفَجْرِ " . قَالَ أَبُو هُرَيْرَةَ اقْرَءُوا إِنْ شِئْتُمْ { وَقُرْآنَ الْفَجْرِ إِنَّ قُرْآنَ الْفَجْرِ كَانَ مَشْهُودًا}
