Sahih Muslim 169b

Muhammad ibn Ishaq al-Musayyibi narrated to us: Anas—meaning Ibn 'Iyad—narrated to us, from Musa—namely, Ibn 'Uqba—from Nafi', who said: 'Abdullah ibn 'Umar said that the Messenger of Allah (peace and blessings be upon him) spoke one day among the people about the Messiah, the Dajjal. He said: Allah, Blessed and Exalted, is not one-eyed. The Messiah, the Dajjal, is blind in his right eye, which is like a swollen grape. The Messenger of Allah (peace and blessings be upon him) also said: Last night I was shown in a dream near the Ka'ba a man of dark complexion, among the finest dark-complexioned men you might see. His locks fell between his shoulders; his hair was well-combed, and water dripped from his head. He had his hands on the shoulders of two men and was circumambulating the House between them. I asked: Who is this? They said: The Messiah, son of Mary. Behind him I saw a man with very tightly curled hair, blind in his right eye, resembling Ibn Qatan more than anyone I have seen. He had his hands on the shoulders of two men and was circumambulating the House. I asked: Who is this? They said: This is the Messiah, the Dajjal.
