And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 Verily We! We established him in the earth, and vouchsafed unto him of everything a way. 84 and he followed a way 85 Until when he reached the setting-place of the sun, he perceived it setting in a miry spring, and he found beside it a nation. We said: Zul Qarnian! either chastise them or take in respect of them the way of kindness. 86 He said, 'As for the evildoer, him we shall chastise, then he shall be returned to his Lord and He shall chastise him with a horrible chastisement. 87 But he who believes and does the right will have an excellent reward, and we shall make things easy for him." 88 Then he followed the road, 89 Until when he reached the land of the rising of the sun, he found it rising on a people to whom We had given no shelter from It; 90 Thus. And We had encompassed [all] that he had in knowledge. 91 Then he followed a way 92 Until, when he reached [a pass] between two mountains, he found beside them a people who could hardly understand [his] speech. 93 They said: 'O Dhu'l-Qarnain, Gog and Magog are oppressing the land. May we pay you some tribute so that you could build a rampart between us and them?" 94 He said: "The ability my Lord has given me is better. So help me with your manual labour; I will build a wall between you and them. 95 Bring me sheets of iron" - until, when he had leveled [them] between the two mountain walls, he said, "Blow [with bellows]," until when he had made it [like] fire, he said, "Bring me, that I may pour over it molten copper." 96 Therefore Yajuj and Majuj were neither able to surmount it, nor could they pierce 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 ۞ On that Day, We shall let them surge against each other like waves and then the Trumpet will be blown and 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 veiled against My warning, and they could not hear. 101
