Musnad Ahmad 25:310

Muhammad ibn Ja‘far narrated to us, Shu‘bah narrated to us, from Simak ibn Harb, from ‘Ikrimah, from Ibn ‘Abbas, from the Prophet, may Allah bless him and grant him peace, that he said regarding the Dajjal: "He is one-eyed, fair-skinned, bright-complexioned, as if his head is a python. He is the most similar of people to ‘Abd al-‘Uzza ibn Qatan. So if the perished one perishes, then your Lord is not one-eyed." Shu‘bah said: I narrated it to Qatadah, and he narrated to me something similar to this.
