Robert Spencer has the installment here
Much of this section concerns a mysterious figure named Dhul-Qarnayn, a conqueror who traveled to the "two horns" - the places where the sun rises and sets. This is generally interpreted figuratively, that Dhul-Qarnayn traveled to the easternmost and westernmost parts of the Eurasian landmass. There is no consensus over his identity; the big problem is that the pre-Islamic emperors of the world were all known to be polytheists. Excluding the Israelite kings, of course - their travels were quite limited.
That the Koran mentions a conqueror without saying what realm he ruled is pure sloppiness.
