Sahih Muslim, Chapter: Faith (Kitab Al Iman)

on the authority of his father 'Umar b. Khattab that he heard from the Messenger of Allah (may peace he upon him) say: I was sleeping when I saw myself making circuit around the Ka'bah, and I saw there a man of fair complexion with straight hair between two men. Water was flowing from his head or water was falling from his head. I said: Who is he? They answered: He is the son of Mary. Then I moved forward and cast a glance and there was a bulky man of red complexion with thick locks of hair on his head, blind of one eye as it his eye was a swollen grape. I asked: Who is he? They said: He is Dajjal. He had close resemblance with Ibn Qatan amongst men.
