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).
