They ask you about Dhu'l-Qarnain. 83 Verily We! We established him in the earth, and vouchsafed unto him of everything a way. 84 Then he followed a way. 85 until when he reached the very limits where the sun sets, he saw it setting in dark turbid waters; and nearby he met a people. We said: "O Dhu al-Qarnayn, you have the power to punish or to treat them with kindness." 86 He said: As to him who is unjust, we will chastise him, then shall he be returned to his Lord, and He will chastise him with an exemplary chastisement: 87 But as for him who believeth and doeth right, good will be his reward, and We shall speak unto him a mild command. 88 Then he followed a way 89 until he came to the rising-place of the sun, where he found it rising on a people for whom We had provided no shelter from it. 90 This indeed was true. We knew all that he did there. 91 Then he followed (another) way, 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 thou Two-Horned One! Behold, Gog and Magog" are spoiling this land. May we, then, pay unto thee a tribute on the understanding that thou wilt erect a barrier between us and them?" 94 He said: That wherein my Lord hath established me is better (than your tribute). Do but help me with strength (of men), I will set between you and them a bank. 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 Thus (Gog and Magog) could neither climb over it nor dig a hole through (the rampart). 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 ۞ 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 And We will present Hell that Day to the Disbelievers, on display - 100 whose eyes were covered against My remembrance, and they were not able to hear. 101
