Abu Huraira said, "I heard Messenger of Allah ﷺ saying, 'The reward of a prayer in congregation is twenty five times greater than that of a prayer offered by a person alone. The angels of the night and the angels of the day gather at the time of Fajr prayer.' " Abu Huraira then added, "Recite the Holy Book if you wish, for "Indeed, the recitation of the Qur'an in the early dawn (Fajr prayer) is ever witnessed." (17:78). (Using translation from Bukhārī 648)
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ تَفْضُلُ صَلَاةُ الْجَمِيعِ صَلَاةَ أَحَدِكُمْ وَحْدَهُ بِخَمْسَةٍ وَعِشْرِينَ جُزْءًا وَتَجْتَمِعُ مَلَائِكَةُ اللَّيْلِ وَمَلَائِكَةُ النَّهَارِ فِي صَلَاةِ الْفَجْرِ ثُمَّ يَقُولُ أَبُو هُرَيْرَةَ فَاقْرَؤَا إِنْ شِئْتُمْ {وَقُرْآنَ الْفَجْرِ إِنَّ قُرْآنَ الْفَجْرِ كَانَ مَشْهُودًا} [الإسراء 78]
