Mishkat al-Masabih #379

‘Abd Khair said: We were sitting looking at ‘Ali when he performed ablution. He inserted his right hand, filled his mouth, rinsed it, snuffed up water and ejected the mucus with the left hand, doing this three times, then said, "If anyone is pleased to look at God's messenger’s method of performing ablution, this is how he did it.” Darimi transmitted it.
