It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him), while mentioning the Dajjal (the False Messiah), said: "I will tell you something about him that no prophet before me has said: he is one-eyed, whereas Allah Almighty is not one-eyed; between his eyes will be written 'Kafir' (disbeliever)." Sayyiduna Jabir (may Allah be pleased with him) also narrated from the Prophet (peace and blessings be upon him): "Every believer will read it, whether he knows how to write or not. He will roam the earth for forty days and will enter every city except these two cities: Madinah and Makkah, for Allah Almighty has forbidden both of them to him. One of his days will be like a year, one day like a month, and one day like a week; then the rest of his days will be like these ordinary days of yours. He will remain (on the earth) for only forty days."
