It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "I saw the Dajjal: moon-white, huge and bulky; as though the hair of his head were the branches of a tree; one-eyed, as though his eye were the morning star. I liken him to Abd al-Uzza, a man of Khuza'ah."
