مَأْجُوج

Appears 2 times in the Quran. (No Root)
  1. They said: O Zulqarnain! surely Gog and Magog make mischief in the land. Shall we then pay you a tribute on condition that you should raise a barrier between us and them

  2. Even when Gog and Magog are let loose and they shall break forth from every elevated place.
