It is narrated from Sayyiduna al-Bara' bin Azib (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever follows a funeral and then prays over it will have one qirat of reward, and whoever walks with the funeral until it is buried will have two qirats of reward; and a qirat is like (Mount) Uhud."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna al-Bara' (may Allah be pleased with him) only with this chain, and Abthar (may Allah have mercy on him) is alone in narrating it."
