paragraph_text: Imam Mahdi, last Imam of the Shia
  
  In Shia Islam, Imam Mahdi is regarded as the prophesied eschatological redeemer of Islam who will rule for seven, nine, or nineteen years (according to differing interpretations) before the Day of Judgment and will rid the world of evil. According to Islamic tradition, the Mahdi's tenure will coincide with the Second Coming of Jesus (ʿĪsā), who is to assist the Mahdi against the Masih ad-Dajjal (literally, the "false Messiah" or Antichrist). Jesus, who is considered the Masih (" Messiah ") in Islam, will descend at the point of a white arcade east of Damascus, dressed in yellow robes with his head anointed. He will then join the Mahdi in his war against the Dajjal, where it is believed the Mahdi will slay the Dajjal and unite humankind.
