Niujie Mosque, or Ox Street Mosque, is the oldest mosque in Beijing and enjoys great reputation among Muslims of all persuasions and nationalities, which is a striking mosque and worth a visit. According to legend, an ancient imam had lived in the catacombs beneath the mosque and if non-believers should attempt to enter its prayer hall, he will suddenly appear and send the "heretic to Allah" by throwing small steel darts at the infidel.
