I heard Allâh's Messenger (ﷺ) saying, "The reward of a (prayer) in congregation is twenty-five times superior in degrees 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." Huraira then added, "Recite (the Holy Book) if you wish, for " Verily, the recitation of the Qur'ân in the early dawn (Fajr prayer) is ever witnessed (attended by the angels in charge of mankind of the day and the night)." (V.17:78). [1:621-O.B.]
