And they ask you about Dhul-Qarnain. Say: "I shall recite to you something of his story." 83 Verily We! We established him in the earth, and vouchsafed unto him of everything a way. 84 So he followed a certain road 85 Till he reached the point of the setting sun, and saw it set behind a muddy lake, and near it found a people. We said: "O Dhu'l-Qarnain, you may either punish them or 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 As for he who believes and does good works he shall receive a fine reward in recompense and we shall speak to him with a mild command' 88 He then followed (another) road 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 Thus. And We had encompassed [all] that he had in knowledge. 91 Then he set out on another expedition 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 Zul-Qarnain – indeed Yajuj and Majuj* are spreading chaos in the land – so shall we assign for you a consideration upon the condition that you set up a wall between us and them?” (* Gog and Magog.) 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; until when he had filled up the space between the two mountain sides, he said: Blow, until when he had made it (as) fire, he said: Bring me molten brass which I may pour over it. 96 Therefore Yajuj and Majuj were neither able to surmount it, nor could they pierce it. 97 Dhu l-Qarnayn said, "This barrier is a blessing from my Lord but when His promise comes to pass He will level it to the ground; His promise always comes true." 98 ۞ And on that day we shall let some of them surge against others, and the Trumpet will be blown. Then We shall gather them together in one gathering. 99 And We will bring forth hell, exposed to view, on that day before the unbelievers. 100 Those whose eyes had been within a cover [removed] from My remembrance, and they were not able to hear. 101
