They will question thee concerning Dhool Karnain. Say: 'I will recite to you a mention of him. 83 Verily We! We established him in the earth, and vouchsafed unto him of everything a way. 84 With these he traveled 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: as for him who doeth wrong, presently we shall torment him, and thereafter he shall be brought back to his Lord, and He shall torment him with a torment formidable. 87 But as for one who believes and does righteousness, he will have a reward of Paradise, and we will speak to him from our command with ease." 88 Thereafter he followed a way. 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 was the state of those people, and We encompassed in knowledge all concerning Dhu al- Qarnayn. 91 Then he followed a way 92 Until, when he reached (a tract) between two mountains, he found, beneath them, a people who scarcely understood a word. 93 They said, "O Dhul-Qarnayn, indeed Gog and Magog are [great] corrupters in the land. So may we assign for you an expenditure that you might make between us and them a barrier?" 94 He said: "(The power) in which my Lord has established me is better (than tribute): Help me therefore with strength (and labour): I will erect a strong barrier between you and them: 95 bring me blocks of iron." Then, when he had filled the gap between the mountain sides [he said], "Now blow on the fire with your bellows." When the iron blocks were red with heat, he said, "Bring me molten brass to pour on them." 96 Such was the rampart that Gog and Magog could not scale, nor could they pierce it. 97 Said [the King]: "This is a mercy from my Sustainer! Yet when the time appointed by my Sustainer shall come, He will make this [rampart] level with the ground: and my Sustainer's promise always comes 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 On that Day We shall lay Hell bare before those who deny the truth, 100 The ones whose eyes were covered from My remembrance, and who could not bear to hear Truth. 101
