Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: The Messenger of Allah (peace and blessings be upon him) said: "The Dajjal will have curly hair, be reddish-white, with a face like the moon; his head is as if it were the branch of a tree. His left eye will be effaced and the other will be like a protruding grape. Among people, the one who most resembles him is Abdul 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."
