Our Prophet (saas) described the car of Hazrat Mahdi (pbuh)

Excerpt from Mr. Adnan Oktar's Live Conversation on A9 TV dated June 15th, 2014

ADNAN OKTAR: He says, "Hazrat Mahdi (pbuh) rides a multicolored horse with white beam of light coming out of its head as a line.” It resembles a projector. A gray horse; see that our Prophet (saas) even tells us the color of the horse. He describes us the shape of the beam of light saying "a white line.” What distance does it travel? For instance, a line of light of ten meters. Where does the light come from? He says, “its head.” And he describes that Hazrat Mahdi (pbuh) “rides a multicolored horse.” And, "This white line emits a beam of light that is strong enough for everyone to see." This is as clear a description of a car as it gets. He means that "There is a beam of light coming out of the head of the car and it can be seen from a long distance." The beam is a straight line, just like the light coming out of a headlight of a car. And the color of the horse is “gray.” Then, Mahdi (pbuh), “will wave the flag of the Messenger of God (saas) who shines light upon both East and West." Isn't this all clear?
