Yahya related to me from Malik from Yahya ibn Said from Wafid ibn Amr ibn Said ibn Muadh from Nafi ibn Jubayr ibn Mutim from Masud ibn al-Hakam from AIi ibn Abi Talib that the Messenger of Allah, may Allah bless him and grant him peace, used to stand up when a funeral procession passed by, and then sit down again afterwards.
