Mukhtasar Muslim

Abu Huraira (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said: Whoever attends a funeral until the prayer is offered (and participates in it), he will have a reward of one qirat, and whoever remains present until the burial, he will have a reward of two qirats. The companions asked, "O Messenger of Allah! What is the meaning of two qirats?" He (peace and blessings be upon him) replied: Like two great mountains in reward.
