They will question thee concerning Dhool Karnain. Say: 'I will recite to you a mention of him. 83 Indeed We established him upon the earth, and We gave him to everything a way. 84 One (such) way he followed, 85 until, when he reached the setting of the sun, he found it setting in a muddy spring, and nearby he found a nation. 'ThulKarnain' We said, 'you must either punish them or show them kindness' 86 He said, "As for one who wrongs, we will punish him. Then he will be returned to his Lord, and He will punish him with a terrible punishment. 87 And as for him who believes and does good, he shall have goodly reward, and We will speak to him an easy word of Our command. 88 Then he followed a road 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had not made against it any shield. 90 So, We encompassed in knowledge what was with him. 91 And once again he chose the right means [to achieve a right end]. 92 Until, when he came between two mountains, he found before them a nation that did not appear to understand any speech. 93 They said, 'O Dhool Karnain, behold, Gog and Magog are doing corruption in the earth; so shall we assign to thee a tribute, against thy setting up a barrier between us and between them?' 94 He said: That in which my Lord has established me is better, therefore you only help me with workers, I will make a fortified barrier between you and them; 95 Bring me ingots of iron!' Until, when he had made all level between the two cliffs, he said, 'Blow!' Until, when he had made it a fire, he said, 'Bring me, that I may pour molten brass on it.' 96 So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration. 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 ۞ And on that Day We shall let some of them surge like waves against others, and the Trumpet shall be blown. Then We shall gather them all together. 99 We will fully expose the view of hell on that Day to the disbelievers, 100 Unto those whose eyes had been under a covering from My remembrance, nor had they been able to hear. 101
