Abu Huraira said, "I heard Allah's Messenger (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:)
حَدَّثَنَا أَبُو الْيَمَانِ، قَالَ أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي سَعِيدُ بْنُ الْمُسَيَّبِ، وَأَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ أَنَّ أَبَا هُرَيْرَةَ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏
"‏ تَفْضُلُ صَلاَةُ الْجَمِيعِ صَلاَةَ أَحَدِكُمْ وَحْدَهُ بِخَمْسٍ وَعِشْرِينَ جُزْءًا، وَتَجْتَمِعُ مَلاَئِكَةُ اللَّيْلِ وَمَلاَئِكَةُ النَّهَارِ فِي صَلاَةِ الْفَجْرِ ‏"‏‏.‏ ثُمَّ يَقُولُ أَبُو هُرَيْرَةَ فَاقْرَءُوا إِنْ شِئْتُمْ ‏{‏إِنَّ قُرْآنَ الْفَجْرِ كَانَ مَشْهُودًا‏}‏
