It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever participates in a funeral, carries the bier, throws soil into the grave, and waits until the burial is completed, will receive a reward equal to two qirats, each of which is as great as Mount Uhud.
