Thauban told how when they went out with the Prophet to a funeral he saw some people riding and said, “Are you not ashamed ? God’s angels are on their feet, while you are on the backs of animals."
Tirmidhi and Ibn Majah transmitted it, and Abu Dawud transmitted something similar. Tirmidhi said it has been transmitted from Thauban in mauquf form.
Abu Huraira reported God’s messenger as saying, “He who follows a bier and carries it three times has accomplished what is ’due to it from him."
Tirmidhi transmitted it, saying that this is a gharib tradition. In Sharh as-sunna it is reported that the Prophet carried the bier of Sa‘d b. Mu'adh between the two poles.
