Abu Dawood: Hadith 112

"All offered the dawn prayer and went 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 of 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 front and back sides, once. He then narrated the tradition in like manner.
