Musannaf Ibn Abi Shaybah

Hazrat Ubaid bin Nastas narrates that we were with Hazrat Abu Ubaidah bin Abdullah at a funeral. Hazrat Abdullah said: When any of you is at a funeral, he should shoulder all four sides of the bier, for indeed this is from the Sunnah. Then he may (voluntarily) lift it again or leave it for others.

Hazrat Abu Huraira (may Allah be pleased with him) narrates that whoever lifted the funeral bier three times has fulfilled the right that was due upon him.

11619 - Yahya ibn Sa'id narrated to us from Thawr from 'Amir ibn (Jushayb) (1) and others from the people of al-Sham (they said) (2): Abu al-Darda said: Part of the complete reward for a funeral is that it is escorted by its family, that it is (carried) (3) by its four corners, and that (earth is thrown) (4) into the grave (5).
