Excerpt from Mr. Adnan Oktar's Live Interview on A9 TV dated January 2nd, 2012
ADNAN OKTAR: [The accounts state that;] "Hazrat Mahdi (pbuh) will go to Bayt al-Maqdis, to Jerusalem." So that means he [Hazrat Mahdi (pbuh)] will be in touch with Israel; that is to say he will be in touch with the Jews. The reason for that is; what does our Prophet (saas) say in his hadiths? "He [Hazrat Mahdi (pbuh) will rule the Jews with the original of the Torah." That is because he is the King Messiah (pbuh) that the Jews have been waiting for. There is only one Mahdi anyway. The Mahdi they [the Jews] have been waiting for and the Mahdi the Muslims are awaiting is the same.
