It is narrated from Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) that he said: "I heard the Messenger of Allah (peace and blessings be upon him) say: 'The two-faced (hypocritical) person in this world will come on the Day of Resurrection with two faces of fire.'"
This hadith is not narrated from Sayyiduna Sa'd (may Allah be pleased with him) except with this chain, and Khalid bin Yazid al-Umari (may Allah have mercy on him) is alone in narrating it.
