Superiority of the Fajr (early morning) prayer in congregation.

Narrated Abu Salama bin 'Abdur Rahman:

Abu Huraira said, "I heard Allah's Apostle 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." (17.18). Narrated 'Abdullah bin 'Umar: The reward of the congregational prayer is twenty seven times greater (than that of the prayer offered by a person alone).

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 ﷺ 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}

Narrated Salim:

I heard Um Ad-Darda' saying, "Abu Ad-Darda' entered the house in an angry mood. I said to him. 'What makes you angry?' He replied, 'By Allah! I do not find the followers of Muhammad doing those good things (which they used to do before) except the offering of congregational prayer." (This happened in the last days of Abu Ad-Darda' during the rule of 'Uthman) .

حَدَّثَنَا عُمَرُ بْنُ حَفْصٍ، قَالَ حَدَّثَنَا أَبِي قَالَ، حَدَّثَنَا الأَعْمَشُ، قَالَ سَمِعْتُ سَالِمًا، قَالَ سَمِعْتُ أُمَّ الدَّرْدَاءِ، تَقُولُ دَخَلَ عَلَىَّ أَبُو الدَّرْدَاءِ وَهْوَ مُغْضَبٌ فَقُلْتُ مَا أَغْضَبَكَ فَقَالَ وَاللَّهِ مَا أَعْرِفُ مِنْ أُمَّةِ مُحَمَّدٍ ﷺ شَيْئًا إِلاَّ أَنَّهُمْ يُصَلُّونَ جَمِيعًا.
