Abdullah bin Umar (may Allah be pleased with them both) narrated that then the Prophet Muhammad (peace and blessings be upon him) addressed the companions: He praised Allah, as is befitting to His majesty. Then he mentioned the Dajjal, and said: I also warn you against his (trials), there has not been any prophet except that he warned his people against his trials; even Noah (peace be upon him) warned his people against him. But I will tell you something about him which no prophet told his people, and that is: the Dajjal will be one-eyed, and Allah, the Exalted, is free from such imperfection.
