Theories about Alexander the Great in the Quran

The story of Dhu al-Qarnayn (in Arabic ذو القرنين, literally "The Two-Horned One"; also transliterated as Zul-Qarnain or Zulqarnain), is mentioned in Surah al-Kahf of the Quran. It has long been recognised in modern scholarship that the story of Dhu al-Qarnayn has strong similarities with the Syriac Legend of Alexander the Great.
