Abu Huraira reported God’s messenger as saying,“If anyone attends the funeral of a Muslim out of faith and seeking a reward from God, and stays till prayer is offered and the burial is complete, he will return with a reward of two qirats, each qirat being equivalent to Uhud (The qirat is a small weight, a twentieth, or twenty-fourth of a dinar. Here it is used somewhat figuratively. The statement that it is equivalent to the hill Uhud is a way of expressing that the reward will be very great); and if anyone prays over the dead and returns before the burial, he will come back with one qirat.”(Bukharl and Muslim.)
