Al-Kahf 96: “Bring blocks of iron.” When he brought the place between the two sides of the mountain to an equal level, he said; “Blow to it” When he made it become like fire, he said; “Bring to me molten copper so that I can pour it over.”

Surah Al-Kahf, verse 96: Bring me blocks of iron. Finally, when he had leveled the space between the two mountainsides, when he had filled the valley, he said: blow, work the bellows. Then, when he had made it glow like embers, he said: bring me some molten copper to pour over it. With the knowledge Allah Almighty taught him, Dhul-Qarnayn asked these people for iron blocks. He placed the iron blocks between the two mountains and stacked them until the mountaintops met one another. Then with a bellows he blew on these heaps of iron, heating them until they became fire. Then, when he poured some molten copper over this iron that had become fire, these heaps of iron turned to bronze; and since there was no force that could (?) this bronze, the way between this people and the peoples of Gog and Magog was blocked.

From the peoples of Gog and Magog, who had plagued them and other people, these people were saved.
