It is narrated from Sayyiduna Abu Musa Ash'ari, may Allah be pleased with him: The Messenger of Allah, peace and blessings be upon him, saw a man performing the Sunnah prayers of Fajr while the muezzin had already begun the iqamah. The Prophet, peace and blessings be upon him, tapped him on the shoulders and said: "Was this person not here before this?"
