Wahb ibn Munabbih
The various campaigns of Dhul-Qarnayn mentioned in Q:18:83-101 have also been attributed to the South Arabian Himyarite King Ṣaʿb Dhu-Marāthid (also known as al-Rāʾid). According to Wahb ibn Munabbih, as quoted by Ibn Hisham, King Ṣaʿb was a conqueror who was given the epithet Dhu al-Qarnayn after meeting al-Khidr in Jerusalem. He then travels to the ends of the earth, conquering or converting people until being led by al-Khidr through the land of darkness. According to Wheeler, it is possible that some elements of these accounts that were originally associated with Sa'b have been incorporated into stories which identify Dhu al-Qarnayn with Alexander.
