It is narrated from Sayyiduna Abu Ubaidah (may Allah be pleased with him) that I heard the Prophet (peace and blessings be upon him) say: "After Prophet Nuh (peace be upon him), every prophet who came warned his people about the Dajjal, and I am also warning you about him." Then the Prophet (peace and blessings be upon him) described some of his characteristics to us, and said: "It is possible that someone who sees me or hears my words may encounter him." The people asked: O Messenger of Allah (peace and blessings be upon him)! What will be the state of our hearts at that time? Will they be like they are today? He said: "Rather, they will be in an even better state than today."
