Sayyiduna Ali (may Allah be pleased with him) narrates that once the Prophet (peace and blessings be upon him) was sleeping and we were sitting nearby discussing the Dajjal. Suddenly, the Prophet (peace and blessings be upon him) woke up, and the color of his blessed face had turned red. The Prophet (peace and blessings be upon him) said: "There is something I fear for you more than the Dajjal."
