(42) باب فَضْلِ صَلاَةِ الجَمَاعَةِ وَبَيَانِ التَّشْدِيدِ فِي التَّخَلُّفِ عَنْهَا
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).
