Volume: 002 / Book Number: 023 / Hadith Number: 462
Narrated Abu Sa'id Al-Khudri :
Allah's Apostle said, "When the funeral is ready (for its burial) and the people lift it on their shoulders, then if the deceased is a righteous person he says, 'Take me ahead,' and if he is not a righteous one then he says, 'Woe to it (me)! Where are you taking it (me)?' And his voice is audible to everything except human beings; and if they heard it they would fall down unconscious . "
