Mukhtasar Bukhari

Narrated Abu Huraira (may Allah be pleased with him): I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "The prayer in congregation is twenty-five times superior (in reward) to the prayer of anyone of you alone. And the angels of the night and the angels of the day gather at the Fajr prayer." After that, Abu Huraira (may Allah be pleased with him) used to say: If you wish, recite this verse: "Indeed, the recitation of the Qur'an at dawn is ever witnessed (i.e., attended by the angels)." (Bani Isra'il: 78)

Abu Musa (may Allah be pleased with him) reports that the Prophet Muhammad (peace and blessings be upon him) said: "Among all people, those who will have the greatest reward for prayer are those whose distance (from the mosque) is the farthest, then those who are farther than them. And the person who waits for the prayer until he prays it with the Imam, in terms of reward, is greater than the one who prays quickly and goes to sleep."
