Abu Dawud Book 1, Hadith Number 118.

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

Narated By N/A : ‘Amr b. Yahya al-Mazini reports on the authority of his father who asked ‘Abd Allah b. Zaid, the grandfather of ‘Amr b. Yahya al-Mazini: Can you show me how the Messenger of Allah (may peace be upon him) performed ablution? ‘Abd Allah b. Zaid replied: Yes. He called for ablution water, poured it over his hands, and washed them; then he rinsed his mouth and snuffed up water in the nose three times; then he washed his face three times and washed his forearms up to elbows twice; then he wiped his head with both hands, moving them front and back of the head, beginning from his forehead, and moved them to the nape; then he pulled them back to the place from where he had started (wiping); then he washed his feet.
