Abu Dawud Book 1, Hadith Number 121.

Chapter : A man who puts his hands in the utensil before washing it.

Narated By Al-Miqdam ibn Ma’dikarib al-Kindi : The ablution water was brought to the Messenger (PBUH) and he performed ablution; he washed his hands up to wrists three times, then washed his forearms three times. He then rinsed his mouth and snuffed up water three times; then he wiped his head and ears inside and outside.
