It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that once the iqamah for prayer was being pronounced, the Noble Prophet (peace and blessings be upon him) also arrived and stood at his place. After a short while, the Noble Prophet (peace and blessings be upon him) remembered that he had not performed ghusl (ritual bath). So, he signaled to the noble companions (may Allah be pleased with them) with his hand to stay where they were, and the Noble Prophet (peace and blessings be upon him) left. When he returned, drops of water were dripping from his head. Then he (peace and blessings be upon him) led us in prayer.
