Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) says: The Messenger of Allah (peace and blessings be upon him) said: "The Dajjal will have curly hair, be reddish-white in complexion, with a face like the moon, as though his head were the branch of a tree. His left eye will be blotted out, and the other will be like a protruding grape. Of all people he most resembles Abd al-Uzza bin Qatan. As for the ruin of those who perish, it is because he is one-eyed, whereas your Lord is not one-eyed."
