Hadith on Jama’ah: Multiplied rewards for praying in congregation

Uthman ibn Affan reported: The Messenger of Allah, peace and blessings be upon him, said, “Whoever prays the evening prayer in congregation is as if he has stood for prayer half of the night. Whoever prays the dawn prayer in congregation is as if he has stood for prayer the entire night.”
