Mukhtasar Sahih Bukhari — Hadith 1347

Sayyiduna Abdullah and Sayyiduna Anas (may Allah be pleased with them) narrate from the Noble Prophet (peace and blessings be upon him) that he said: "On the Day of Resurrection, every deceitful person will have a flag." One narrator says: "That flag will be set up," and another says: "It will be shown on the Day of Resurrection by which it will be recognized that this person was deceitful."
