Sayyiduna Abu Umamah (may Allah be pleased with him) says: Had I heard this from the Messenger of Allah (peace and blessings be upon him) only seven times, I would still not have narrated it. The Messenger of Allah (peace and blessings be upon him) said: "When a man performs ablution as he has been commanded, sin departs from his ears, his eyes, his hands and his feet."
