The name literally means "the possessor of two horns" or "the two horned one",
When looking at Quranic terminology one finds that the term horn usually refers to a sprung people, people of an age or generation.
Ch 36 yaseen uses the term quroon (plural of horn) when refering to generations.
So if it's metaphorical (something chapter 18 keeps appearing as) and happens in the future (as possibly alluded to by the advice to read it during the fitnah of dajjal), then it's a man of two generations/epochs who meets gog and magog.
The hadith tell us that one man who appears in two generations faces off with gog and magog.
But Allah alone knows the unseen and knows how it will pan out,
And since He (swt) sent a definite to destroy the people of Yunus (pbuh), but repented of the punishment when the people of nineveh repented, who's to know which part of the prophecy swarm plays out?
Allah swt can abrogate whatever He likes.
I hope we're not disappointed if everyone repents and none of the scary events happen.
Though it seems like wishful thinking to imagine everyone will fix up.
Very true. However I also want to point out that the term "Dhul Qarnayn" most likely refers to the fact that he reached the earths most westerly and easterly points during his travels - the horn of the west and the horn of the east. Let's contextualize the term.
The Jews tested the Prophet pbuh with the question "Tell us about the young man who travelled a great distance"
Within this understanding, we can safely assume that the Jews the term "Dhul Qarnayn" and so, when the ayaat (no.83) starts with "And they ask thee (O Muhmammad) about Dhul Qarnayn, say to them
I shall recite to you a remembrance about him"
The ayaat then go on to confirm that this man travelled a great distance to the west in order to spread Islamic Monotheism, and in doing so reaches the furthest west where he finds the sun to appear setting in the sea... the ayaat then go on to confirm that he travels east in order to spread Islamic Monotheism and reaches the furthest East where the sun appears to rise from... along the way Allah mentions some landmarks, in order to show us the great distance that Dhul Qarnayn had travelled.
The terms "Dhul Qarnayn" was known by the Jews, thus they did not argue or contest the Ayaat regarding him.
How did the Jews know about this? Easy... look in their holy texts. Daniels prophecy, in Isaiah... in fact he is mentioned 23 times buy name and alluded to several times more - further, non biblical accounts from historians such as Herodotus and Josephus (who were also Jews btw) give away much as to the term "Dhul Qarnayn"... in fact, in Herodotus' Histories, book 1 volum 1 - the very first story mentioned is the story of Cyrus...
...Cyrus was hailed as a Messiah to the Jews, even though Cyrus himself was not a Jew but a mixed race child of a Persian mother and Mede father...
in fact, one thing you will notice with Cyrus, is that however you try to fit the term "dhul qarnayn" to him, it always works - but not with Alexander, or the Tubba Kings, or anyone else for that matter.
At first, when I was discussing this with bro Ministry of Truth in WUP, and on skype, we both agreed that personally we didn't want Dhul Qarnayn to be Cyrus because we just didn't like Cyrus for some reason lol... the more I investigated, the more I became convinced that Cyrus was indeed the DHul Qarnayn of the Quran.
And Allah knows best
