It is narrated from Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him); he said: When the Messenger of Allah (peace and blessings be upon him) performed ablution, he would sniff water into his nose three times and rinse his mouth, and put his two fingers into his mouth; when he washed his face, he would reach with his palms to the front part of his ears; when he wiped his head, he would wipe the back part of his ears with his fingers along with his head; and he would do khilal of his beard.
