Dajjal is an evil figure in Islamic eschatology (end times beliefs). He is often referred to as the "False Messiah" or "Antichrist" and is believed to be a false prophet who will appear before the end of the world and deceive many people. According to Islamic tradition, Dajjal will have supernatural powers and will try to lead people astray from the true faith. He is said to have one blind eye, and will be defeated by the Prophet Jesus before the end of the world. The belief in Dajjal is a fundamental part of Islamic theology, and Muslims are encouraged to be vigilant and protect themselves from his deception.
