The Narrative of Alexander the Great in the Quran

Alexander the Great or Dhul-Qarnayn

Muslim scholars have linked the narrative of  Dhul-Qarnayn in the Quran with the story of Alexander the Great. The first to have identified this link is the Muslim hagiographer Ibn Hisham (?-833 AD) in the Sira literature.

The story of Dhul-Qarnayn

Dhul-Qarnayn is mentioned in only one place in the Qur'an, specifically in Surah Al-Kahf. The Qur'anic story tells about a man called Dhul-Qarnayn, the translation of which is literally "the Two-Horned". It is said that the legend of the man was known to the people of the region. In the Qur'an, Dhul-Qarnayn who was given great power by Allah, traveled to the rising place and setting place of the sun. There, he found the sun setting in a murky (or boiling) sea. He built a wall in order to enclose the nations of Gog and Magog. It is thought that Gog and Magog will breach Dhul-Qarnayn's wall before Yaum al-Qiyāmah (the Day of Judgement) and will wreak havoc in the world.
