It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever is two-tongued (that is, two-faced), Allah Almighty will give him two tongues of fire on the Day of Resurrection."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ayyub except Asad, and no one narrated it from Qatadah except Ayyub and Isma'il bin Muslim."
