Sayyiduna Abu Ubaidah bin Jarrah (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings of Allah be upon him) say: "Every prophet before me has warned his people about the Dajjal, and I am also warning you about him." The narrator says: Then the Prophet (peace and blessings of Allah be upon him) described his appearance before us. The Prophet (peace and blessings of Allah be upon him) said: "It is possible that someone may reach him who has seen me, or has heard my speech." The people said: "O Messenger of Allah! On that day, will our hearts be like they are today?" The Prophet (peace and blessings of Allah be upon him) said: "They will be even better than today."
