It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) that a Bedouin came to the Noble Prophet (peace and blessings be upon him) and was asking about ablution. The Prophet (peace and blessings be upon him) demonstrated ablution to him by washing each part three times and said: "This is ablution. Whoever washes more than this has done wrong, has exceeded the limit, and has committed injustice."
