Sahih Bukhari Hadith, Volume 4, Book 55, Number 649:
The Prophet mentioned the Massiah Ad-Dajjal in front of the people saying, Allah is not one eyed while Messsiah, Ad-Dajjal is blind in the right eye and his eye looks like a bulging out grape. While sleeping near the Ka'ba last night, I saw in my dream a man of brown color the best one can see amongst brown color and his hair was long that it fell between his shoulders. His hair was lank and water was dribbling from his head and he was placing his hands on the shoulders of two men while circumambulating the Kaba. I asked, 'Who is this?' They replied, 'This is Jesus, son of Mary.' Behind him I saw a man who had very curly hair and was blind in the right eye, resembling Ibn Qatan (i.e. an infidel) in appearance. He was placing his hands on the shoulders of a person while performing Tawaf around the Ka'ba. I asked, 'Who is this?' They replied, 'The Masih, Ad-Dajjal.'
Notice that Mohammed is saying that Masih, Ad-Dajjal is not Jesus, the son of Mary. But notice that the argument he makes for it, initially, is that "Allah is not one eyed ..." whereas Masih, Ad-Dajjal is. I realize that a Muslim is not going to be persuaded by the uncorroborated testimony of a single report in the Hadith, but it is at least a puzzling way for Mohammed to describe the matter, if he did not recognize that Jesus, as Messiah, is God in the Flesh.
