Dhu al-Qarnayn

, (, ; "The Two-Horned One") appears in the Quran, Surah al-Kahf (18), Ayahs 83–101 as one who travels to east and west and sets up a barrier between a certain people and Gog and Magog (). Elsewhere, the Quran tells how the end of the world 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 ().

Dhu al-Qarnayn has most popularly been identified by Western and traditional Muslim scholars as Alexander the Great. However, Wheeler and a number of Muslim scholars differed, identifying the character with several other historical figures, such as the South Arabian king Sa'b Dhu Marathid and the North Arabian king al-Mundhir ibn Imru al-Qays, with modern Muslim commentators such as Maududi leaning in favour of identifying him as Cyrus the Great.
