"The Messenger of Allah said: 'There is a devil for ablution who is called Walahan, so be on guard against the insinuating thoughts (Waswas) about water.'"
Sunan Ibn Majah Book 1, Hadith 155
← Previous Hadith The Messenger of Allah called for water and performed ablution once. He said: "This is the minimum requirement of ablution' or he said: 'The ablution of one who, if he does not perform this ablution, Allah will not accept his prayer." Then he performed ablution washing each part twice, and he said: 'This is the ablution of one who, if he performs it, Allah will give him two shares of reward." Then he performed ablution washing each part three times, and said: 'This is my ablution and the ablution of the Messengers who were sent before me."

Sunan Ibn Majah Book 1, Hadith 154 Next Hadith → A Bedouin came to the Prophet and asked him about ablution. He showed him how to perform it washing each part of the body three times. Then he said: 'This is the ablution, and whoever does more than this, has done evil, transgressed the limits and wronged himself.'"
