It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that a funeral passed by the Noble Prophet (peace and blessings be upon him), and people began to mention his good qualities and praise him. The Noble Prophet (peace and blessings be upon him) said: "It has become obligatory." In the meantime, another funeral passed by, and people mentioned his bad qualities and criticized him. The Noble Prophet (peace and blessings be upon him) said: "It has become obligatory." Then he said: "You are Allah's witnesses on the earth."
