It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Once I saw in a dream, near the Ka'bah, a man of wheat-colored complexion and straight hair, who had placed his hand on the shoulders of two men. Drops of water were falling from his head. I asked, 'Who is this?' It was made known to me that this is Sayyiduna Isa (Jesus, peace be upon him). Then behind him I saw a man with curly hair, reddish complexion, blind in the right eye, and, according to my sight, he resembled Ibn Qatan the most. I asked, 'Who is this?' It was made known to me that this is the Messiah Dajjal."
