Ibn Aun reports: I asked Muhammad, "When I lower the deceased into the grave, what should I say?" He replied, "Nothing."

Hazrat Asim bin Hamzah narrates that Hazrat Ali (may Allah be pleased with him, may Allah honor his face) used to say at the time of sleeping and when lowering the deceased into the grave: BISMILLAHI WA FEE SABILILLAH, WA ‘ALA MILLATI RASOOLILLAHI SALLALLAHU ‘ALAYHI WA SALLAM. "With the name of Allah, in the way of Allah, and upon the religion of the Messenger of Allah, peace and blessings be upon him."
