Funerals (Al-Janaa'iz)
Bukhari :: Book 2 :: Volume 23 :: Hadith 396
Narrated Said Al-Maqburi:
That his father said, "While we were accompanying a funeral procession, Abu Huraira got hold of the hand of Marwan and they sat down before the coffin was put down. Then Abu Said came and took hold of Marwan's hand and said, "Get up. By Allah, no doubt this (i.e. Abu Huraira) knows that the Prophet forbade us to do that." Abu Huraira said, "He (Abu Said) has spoken the truth."
