Musnad Ahmad 27:1639

Surayj narrated to us, Fulayh narrated to us, from Nafi’, from Ibn ‘Umar, who said: The Messenger of Allah (ﷺ) said: "I saw myself in a dream at the Ka’bah, and I saw a man of brown complexion, the best of what you see of men, having hair reaching his earlobes that had been combed, and his hair was dripping with water, placing his hands on the shoulders of two men, circumambulating the House, with straight hair. I said: 'Who is this?' They said: 'The Messiah, son of Maryam.' Then I saw a man with curly, kinky hair, blind in his right eye, as if his eye were a floating grape, resembling most of the people I have seen, Ibn Qatan, placing his hands on the shoulders of two men, circumambulating the House. I said: 'Who is this?' They said: 'This is the Messiah Dajjal.'"
