Magog's appearance in the Quran and other Islamic sources is chiefly due to his apocalyptic renown as part of the pairing of Gog and Magog (Arabic: Ya'juj wa Ma'juj). In sura Al-Kahf ("The Cave", 18:83–98) of the Quran (early 7th century AD), an individual called Dhul-Qarnayn ("The Two-horned One") journeys to a distant land in a pass between two mountains where he finds people who are suffering from the mischief of Gog and Magog.
