18.91 - Thus, and We encompassed what he had with knowledge. 18.92 - Then he followed a cause. 18.93 - Until, when he reached between the two dams, he found near them a people who could hardly understand a saying. 18.94 - They said: O Zul-Qarnayn! Indeed, Yagog and Magog are mischief makers in the land. So may we make for you an exit that you might make between us and them a dam? 18.95 - He (Zul-Qarnaan) said: What my Lord has established me over is better, so help me with strength, (and) I will make between you and them a bank. 18.96 - Bring me blocks of iron; until, when he had levelled between the two hills, he said: Blow, until when he had made it (like) fire, he said: Bring me, that I may pour over it molten brass. 18.97 - So they (Yagog and Magog) were not able to pass it, nor could they make in it a hole. 18.98 - He (Zul-Qarnayn) said: This is a mercy from my Lord; and when the promise of my Lord comes, He will make it levelled. And ever is the promise of my Lord true. 18.99 - And We will leave some of them on that day surge against others; and the trumpet will be blown, so We will gather them in gathering. 18.100 - And We will display hell on that day before the unbelievers, on display.
