Hadith 1749
Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "A man's prayer performed with the congregation is twenty-five times more virtuous than his prayer performed alone. If a person offers prayer in a deserted place, completes his ablution, and performs the bowing and prostration properly, he will receive the reward of twenty-five prayers."
