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 two men. Water drops were falling from his head. I asked, 'Who is this?' It was made known to me that he is Sayyiduna Isa (peace be upon him). Then behind him, I saw a man with red complexion, curly hair, blind in the right eye, and, according to my sight, extremely resembling Ibn Qatan. I asked, 'Who is this?' It was made known to me that he is the Masih Dajjal."
