Abu Dawud Book 1, Hadith Number 112.

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

Narated By ‘Abd Khair : ‘Ali offered the dawn prayer and went out to Rahbah (a locality in Kufah). He called for water. A boy brought him a vessel containing water and a wash-basin. He held the vessel with his right hand and poured water over his left hand. He washed both his hands (to the wrist) three times. He then put his right hand in the vessel (to take water) and rinsed his mouth three times and snuffed up water three times. He then narrated almost the same tradition as narrated by Abu ‘Awanah. He then wiped his head, both its back and front sides, once. He then narrated the tradition in a like manner.
