Sahih Bukhari Volume 001, Book 004, Hadith Number 142.

Narated By 'Ata' bin Yasar : Ibn 'Abbas performed ablution and washed his face (in the following way): He ladled out a handful of water, rinsed his mouth and washed his nose with it by putting in water and then blowing it out. He then, took another handful (of water) and did like this (gesturing) joining both hands, and washed his face, took another handful of water and washed his right forearm. He again took another handful of water and washed his left forearm, and passed wet hands over his head and took another handful of water and poured it over his right foot (up to his ankles) and washed it thoroughly and similarly took another handful of water and washed thoroughly his left foot (up to the ankles) and said, "I saw Allah's Apostle performing ablution in this way."
