What a suprizing reply!
In the name of God
At first I should say you are in a deep mistake!
And after that I should say you just shocked me.
Mahdi and Jesus are not the only characters, the story has more!!
The antichrist in Islam is called "Dajal" or the lier that will be killed by Jesus.
And the False Prophet is "Sefyani" that will suddenly burried in ground in the "Beyda" area by order of God
I said if you want to know details just ask! Dont get result so quick!!
