They said, “O Dhul-Qarnain, the (tribes of) Ya’jūj and Ma’jūj (Gog and Magog) are mischief-makers on the earth. So, should we assign a tax for you on condition that you make a barrier between us and them?”

He said, “What my Lord has (already) given in my control is better enough (for me than the tax you are offering to me), so help me (only) with some (man) power, and I shall make a rampart between you and them.

Bring me big pieces of iron.” (They proceeded accordingly) until when he leveled up (the gap) between the two cliffs, he said, “Blow.” (They complied) until when he made it (like) fire, he said, “Bring me molten copper, and I will pour it upon this.”

So they (Ya’jūj and Ma’jūj) were not able to climb it, nor were they able to make a hole in it.

He said, “This is a mercy from my Lord. Then, when the promise of my Lord will come, He will make it leveled to the ground. The promise of my Lord is true.”

And on that day, (i.e. the Doomsday) We will leave them (all the people including Ya’jūj and Ma’jūj) surging over one another. And the Horn shall be blown, then We shall gather them together.

And on that day We will bring Jahannam fully exposed before the infidels

whose eyes were under a cover against My reminders, and they were not able to listen.

Do, then, the disbelievers deem (it fit) that they take My servants as patrons beside Me? Surely, We have prepared Jahannam as entertainment for the disbelievers.
