And they ask thee of Zul Qarnain. Say thou: I shall recite unto you of him some mention. 83 We granted him power in the land and endowed him with all kinds of resources. 84 So he followed a way. 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 for him who doeth wrong, we shall punish him, and then he will be brought back unto his Lord, Who will punish him with awful 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 And once again he chose the right means [to achieve a right end]. 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 thus [We had made them, and thus he left them; and We did encompass with Our knowledge all that he had in mind 91 Then he followed (another) 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 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 Give me pieces of iron - till, when he had levelled up (the gap) between the cliffs, he said: Blow! - till, when he had made it a fire, he said: Bring me molten copper to pour thereon. 96 So they were unable either to scale it or pierce it. 97 He said, “This is the mercy of my Lord; then when the promise of my Lord arrives, He will blow it to bits; and my Lord’s promise is true.” 98 ۞ And We shall leave them on that day surging one against other and the trumpet shall be blown, and then We shall assemble them together. 99 We will fully expose the view of hell on that Day to the disbelievers, 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
