It is narrated from Sayyiduna Uthman (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever performs the Isha and Fajr prayers in congregation, it is as if he has stood in prayer for the entire night. And in another narration, it is stated: Whoever performs the Isha prayer in congregation, it is as if he has stood in prayer for half the night, and whoever also performs the Fajr prayer in congregation, it is as if he has stood in prayer for the entire night.
