Sa'd bin Ibrahim سعد بن إبراهيم بن عبد الرحمن · The Book on Jana''iz (Funerals)

"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.'"

The Messenger of Allah said: "Whoever consoles a bereaved mother, he will be clothes with a Burd in Paradise."

"The Messenger of Allah said, 'Allahu Akbar' over the deceased, so he raised his hands with the first Takbir, and he placed his right (hand) over his left."
