Dhul-Qarnayn

Dhu'l-Qarnayn is a leader who appears in the Quran, Surah al-Kahf (18), Ayahs 83–101, as one who travels to the east and west and sets up a barrier between a certain people and Gog and Magog. Elsewhere, the Quran tells how the End Times will be signaled by the release of Gog and Magog from behind the barrier. Other apocalyptic writings predict that their destruction by God in a single night will usher in the Day of Resurrection.
