After the caliph reported a dream in which he saw the Iron Wall of Dhul-Qarnayn being breached by Yajuj and Majuj , he dispatched me to investigate the matter. Heading northwards to the Caucasus, I arrived in Tbilisi after six months of travel. There I made inquiries concerning the state of the Iron Wall, and found an old Magian who told me that he had seen the Iron Wall, and that it still stood. I then offered him twenty dinars to lead me to the Iron Wall, and without comment he led me further northward, to a pass between the mountains of ███████ and ████. There I beheld the Iron Wall, and to the relief of both the caliph and myself, I found that the Iron Wall still stood, and that Dhul-Qarnayn's construction equipment remained intact, scattered about the site.

What I found strange, however, was that I could see the scratches made by Yajuj and Majuj on the Iron Wall, but I could not see Yajuj and Majuj themselves. When I expressed my confusion to the Magian, he told me that the people of Yajuj and Majuj lie hidden beyond the Iron Wall. He then placed his hand on my shoulder, at which point I saw the horde of Yajuj and Majuj streaming towards us as they tore at the Iron Wall. They were as gruesome as I had imagined, for their nakedness was not even hidden by skin, and their hands ended not in nails, but vicious rending claws.

Behind the horde of Yajuj and Majuj, I saw only devastation: every tree and plant had been uprooted, and the only beasts that survived their onslaught were flies, maggots, and roaches. Examining the disposition of the forces of Yajuj and Majuj more closely, I saw two masked men, cloaked in red robes like those of Roman bishops, presiding over the horde from atop flesh-crafted towers. Before them stood a massive, four-legged beast that was larger than five elephants and had only a bony plate for a face. Raising their staves towards the air, they guided the beast as a performer might guide a puppet. Responding to their every gesture, the beast began to charge toward the Iron Wall, trampling underfoot the Yajuj and Majuj that strayed into its path, before its head slammed into the Iron Wall, which emerged largely unscathed.

I questioned the Magian as to why Yajuj and Majuj continued this futile effort to penetrate the Iron Wall, when they could have undermined it or built a scaffold. He replied that where Yajuj and Majuj stood, the ground was harder than Damascus steel and the ceiling of heaven was exactly at the height of the Iron Wall, so that even the most insignificant insect could not fly over it. I told the Magian that I had seen enough, and he removed his hand from my shoulder. As Yajuj and Majuj disappeared from my sight, he told me that the caliph and the rulers of every civilized land must heed the threat of Yajuj and Majuj. Sometimes I question whether my vision was a sign from Allah or a Magian trick, but I am inclined to believe that I was not deceived, for Allah is Knowing and Seeing, and I saw only what had already been revealed.
