"I heard the Messenger of Allah, while he was performing Salat for a deceased person. I could hear him saying in his prayer: (Allahummagfir lahu, war hamhu, waghsilhu bil-baradi (waghsilhu) kama yughsaluth-thawb) 'O Allah! Forgive him, have mercy upon him, and wash him with (snow or ice) (and wash him) just as a garment is washed.'"
