Sayyiduna Abu al-Darda (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "Whoever mentions another person with something that is not in him, in order to fault him with something that is not in him, Allah Almighty will confine him in the Fire of Hell until he has fully served (the punishment for) what he said."
This narration was recorded by Imam al-Tabarani in al-Mu'jam al-Awsat from his teacher Miqdam bin Dawud, who is da'if (weak).
