The Messenger of Allah said: "Part of the Fitrah is rinsing out the mouth, rinsing out the nostrils, using the tooth stick, trimming the mustache, clipping the nails, plucking the armpit hairs, shaving the pubic hairs, washing the joints, washing the private parts and circumcision.'"

"I saw the Messenger of Allah performing ablution, and he ran his little finger between his toes." (Sahih) Another chain with similar wording.

"I heard the Messenger of Allah say: 'Perform ablution after (eating) camel meat, but do not perform ablution after (eating) mutton. Perform ablution after (drinking) camel's milk, but do not perform ablution after (drinking) sheep's milk. Perform prayer in the sheep pens but not do in the camels' Ma'atin.'"

"I put out water for the Messenger of Allah for a bath, and he had a bath after going to all of his wives in one night."
