And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 And he followed a road 85 Until, when he reached the setting of the sun, he found it [as if] setting in a spring of dark mud, and he found near it a people. Allah said, "O Dhul-Qarnayn, either you punish [them] or else adopt among them [a way of] goodness." 86 He answered: "As for him who does wrong [unto others] - him shall we, in time, cause to suffer; and thereupon he shall be referred to his Sustainer, and He will cause him to suffer with unnameable suffering. 87 But he who believes and does the right will have an excellent reward, and we shall make things easy for him." 88 He travelled again 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 So (it was)! And We knew all about him (Dhul-Qarnain). 91 And once again he chose the right means [to achieve a right end]. 92 Until, when he reached [a pass] between two mountains, he found beside them a people who could hardly understand [his] speech. 93 'ThulKarnain' they said, 'Look, Gog and Magog are corrupting the earth. Build for us a barrier between us and them, and we will pay you a tribute' 94 He said, 'That wherein my Lord has established me is better; so aid me forcefully, and I will set up a rampart between you and between them. 95 Bring me lumps of iron. Then when he had evened up between the two mountain-sides, he said: blow! Then when he had made it fire, he said: bring me and I shall pour thereon molten copper. 96 So they were not able to scale it nor could they make a hole in 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 will leave a part of them in conflict with another part, and the trumpet will be blown, so We will gather them all together; 99 We will fully expose the view of hell on that Day to the disbelievers, 100 whose eyes were covered against My remembrance, and they were not able to hear. 101
