It is narrated from Hazrat Qais bin Amr (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) saw a man performing two rak'ahs after the Fajr prayer. He said, "Is the Fajr prayer performed twice?" The man replied, "I was not able to perform the two Sunnah rak'ahs before Fajr, so I have performed them now." Upon this, the Noble Prophet (peace and blessings be upon him) remained silent.
