Musnad Ahmad 27:528

Ishaq ibn Sulayman narrated to us, I heard Hanzalah ibn Abi Sufyan, I heard Salim say: I heard Abdullah ibn Umar say: The Messenger of Allah (peace and blessings of Allah be upon him) said: "I saw at the Kaaba, from the side facing it, a man of brown complexion, with straight hair, placing his hands on two men, while his head was pouring or dripping [water]. I said: 'Who is this?' They said: 'Isa ibn Maryam (Jesus, son of Mary) or the Messiah, son of Mary.' And I saw behind him a man of reddish complexion, blind in his right eye, with curly hair, the person I have seen who most resembles him is Ibn Qatan. I said: 'Who is this?' They said: 'The Messiah Dajjal (the Antichrist).'"
