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). (Using translation from Muslim 649b)
أَنَّ النَّبِيَّ ﷺ قَالَ تَفْضُلُ الصَّلَاةُ فِي الْجَمِيعِ عَلَى صَلَاةِ الرَّجُلِ وَحْدَهُ خَمْسًا وَعِشْرِينَ وَتَجْتَمِعُ مَلَائِكَةُ اللَّيْلِ وَمَلَائِكَةُ النَّهَارِ فِي صَلَاةِ الْفَجْرِ ثُمَّ يَقُولُ أَبُو هُرَيْرَةَ اقْرَءُوا إِنْ شِئْتُمْ {وَقُرْآنَ الْفَجْرِ إِنَّ قُرْآنَ الْفَجْرِ كَانَ مَشْهُودًا} [الإسراء 78]
