Chapter: when should one sit after standing for the funeral procession?

The Prophet (ﷺ) said, "If any one of you see a funeral procession and he is not going along with it, then he should stand and remain standing till he gets behind it, or it leaves him behind, or the coffin is put down before it goes ahead of him. "

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 Sa`id 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 Sa`id) has spoken the truth."
