Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates from the Prophet (peace and blessings be upon him) that he said: "Whoever offers the funeral prayer will have one qirat, and whoever follows it until it is placed in the grave will have two qirats." (Abu Hazim) said: I said: O Abu Hurayrah, what is a qirat? He said: Like Uhud.
