Dhul-Qarnayn (Arabic ذو القرنين ḏū al-qarnayn, IPA: [ðuːlqarˈnajn]), literally "He of the Two Horns", is a figure mentioned in the Qur'an, the sacred scripture of Islam, where he is described as a great and righteous ruler who built a long wall that keeps Gog and Magog from attacking the people of the West.

Dhul-Qarnayn is, according to traditional Islamic scholars, the same man as Alexander the Great,[1] who is ascribed similar adventures in the Alexander romance; according to a classical interpretation, the name is due to his having reached the two 'Horns' of the Sun, east and west, where it rises and where it sets" during his campaign.[2] Some contemporary Islamic scholars have argued for an identification with other figures such as Cyrus the Great instead. Most secular scholars studying Islam have been concord in their view that there is strong evidence supporting the conclusion that Dhul-Qarnayn is none other than Alexander the Great in the Qur'an.

In the Bible the False Prophet has two horns, who is yet to be revealed in the Tribulation. According to Watchman Nee the two horns of the False Prophet point to 1) mischievousness and 2) giving life to the image of the Antichrist beast. The Tribulation occurs in the last 7 years before Jesus returns in Person.

I can't help but think all these others alleged to be the False Prophet, the 2nd Beast, are a diversion from noticing who the actual False Prophet will be: revived Judas.
