In the Torah:
[Allah:] "I have stirred up ONE FROM THE NORTH, and he comes—one from the rising sun who calls on My name. He treads on rulers as if they were mortar, as if he were a potter treading the clay… I gave to Jerusalem a messenger of good tidings."
Here, it is noted that the leader who will come from the North of Israel is a person praying to Allah before the rising of the Sun. Besides, this person –Hazrat Mahdi (pbuh)- who is the giver of glad tidings will make the leaders advocating atheistic ideologies fail with his knowledge and wisdom.
In the commentaries regarding above passage from the Torah:
"WHEN THE KING MOSHIACH WHO IS IN THE NORTH WIL ARISE, he will come and build the Beis Hamikdash [Masjid of the Prophet Solomon (pbuh)] which is situated in the South." (Mishnah, Midos 2:1; Jerusalem Talmud, Megillah 1:11)
In other Judaic commentaries there is an indication that King Messiah –Hazrat Mahdi (pbuh)– should be sought for "at the Gates of Rome." Istanbul, the capital city of Roman Empire, was given the name "Nova Roma" in Latin, that is "New Rome," by Constantine I. In the passage of the Torah above, there is also an indication that the King Messiah –Hazrat Mahdi (pbuh)– will come from the North of Israel, which is Turkey.
