They will ask you about Dhu'l-Qarnayn. Say, "I will give you an account of him." 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 He journeyed on a way 85 [And he marched westwards] till, when he came to the setting of the sun, it appeared to him that it was setting in a dark, turbid sea; and nearby he found a people [given to every kind of wrongdoing]. We said: "O thou Two-Horned One! Thou mayest either cause [them] to suffer or treat them with kindness!" 86 He said: "We will chastise him who does wrong, whereafter he will be returned to his Lord and He will chastise him grievously. 87 As for those who believe and do good, they will receive virtuous rewards and We will tell them to do only what they can. 88 Thereafter he followed a way. 89 To the extent that when he reached the rising-place of the sun, he found it rising upon a nation for which We had not kept any shelter from it. 90 Thus it was. And surely We have encompassed all that was with him in knowledge 91 He then followed (another) road 92 Till he reached a place between two mountains, and found this side of it a people who understood but little of what was spoken. 93 'ThulKarnain' they said, 'Look, Gog and Magog are corrupting the earth. Build for us a barrier between us and them, and we will pay you a tribute' 94 He answered: "Whatever my Lord has granted me is good enough. But help me with your labour and I will erect a rampart between you and them. 95 Bring me ingots of iron," (which they did) until the space between two mountain sides was filled up. "Blow your bellows," he said; (and they blew) until it was red hot. "Bring me molten brass," he said, "that I may pour over it." 96 So they [Ya'juj and Ma'juj (Gog and Magog)] were made powerless to scale it or dig through it. 97 He said: "This is a mercy from my Lord: But when the promise of my Lord comes to pass, He will make it into dust; and the promise of my Lord is true." 98 ۞ We shall leave them on that day surging like waves pressing one against the other, and the trumpet blast will be sounded, when We shall gather them all together. 99 We will fully expose the view of hell on that Day to the disbelievers, 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
