Muwatta Malik #558
Burials
Yahya related to me from Malik that he had heard that Umm Salama,
the wife of the Prophet, may Allah bless him and grant him peace, used
to say, "I did not believe that the Messenger of Allah, may Allah
bless him and grant him peace, had died until I heard the pickaxes
fall."
