They ask you about Dhu'l-Qarnain. 83 Say: "I will cite before you his commemoration." We gave him authority in the land and means of accomplishing every end. 84 So he followed a course. 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, "We shall certainly punish him who does wrong; then he shall be brought back to his Lord who will punish him with a grievous punishment, 87 But as for him who believes, and does righteousness, he shall receive as recompense the reward most fair, and we shall speak to him, of our command, easiness.' 88 And once again he chose the right means [to achieve a right end]. 89 Until when he reached the rising place of the sun, he perceived it rising upon a nation for whom against it We had not set a veil. 90 So (it was). And We knew all concerning him. 91 Then he followed still another path, 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! the Gog and Magog (People) do great mischief on earth: shall we then render thee tribute in order that thou mightest erect a barrier between us and them? 94 He answered: "That wherein my Sustainer has so securely established me is better [than anything that you could give me]; hence, do but help me with [your labour's] strength, [and] I shall erect a rampart between you and them! 95 "Give me pieces (blocks) of iron," then, when he had filled up the gap between the two mountain-cliffs, he said: "Blow," till when he had made it (red as) fire, he said: "Bring me molten copper to pour over it." 96 Such was the rampart that Gog and Magog could not scale, nor could they pierce it. 97 He said: This is a mercy from my Lord; but when the promise of my Lord cometh to pass, He will lay it low, for 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 That will be the Day We shall place Hell before the unbelievers 100 Those whose eyes were hoodwinked from My reminder, and who could not bear to hear. 101
