It was narrated that Abu Ma`mar said: We were with ‘Ali (رضي الله عنه) when a funeral passed by him and some people stood up for it. ‘Ali (رضي الله عنه) said: Who told you to do this? They said: Abu Moosa, He said: The Messenger of Allah (ﷺ) only did that once, following the example of the People of the Book, but when he was forbidden to do it, he stopped.
