Hameed bin Ziyad حميد بن زياد أبو صخر · Funerals (Kitab Al-Jana'iz)

If anyone attends the funeral and prays over (the dead), he will get the reward of one qirat, and if anyone attends the funeral until the completion (of the burial), he will get the reward of two qirats, the smaller of them being equivalent of Uhud, or one of them being equivalent to Uhud.
