It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: "Every prophet before me has certainly described the appearance of the Dajjal to his nation, and I will tell you a sign about him which no prophet before me has told his nation: the Dajjal will be one-eyed, and Allah cannot be one-eyed. His (the Dajjal's) right eye will be swollen like a grape."
