(31) باب فَضْلِ صَلاَةِ الْفَجْرِ فِي جَمَاعَةٍ
Narrated Abu Salama bin `Abdur Rahman:
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."
(17:78).
