They ask you about Dhu'l-Qarnain. 83 We had given him great power in the land and all kinds of resources. 84 Then he followed a way. 85 Until, when he reached the setting of the sun, he found it set in a spring of murky water: Near it he found a People: We said: "O Zul-qarnain! (thou hast authority,) either to punish them, 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 believes and acts righteously, his will be a goodly reward and we shall enjoin upon him only mild commands." 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 Thus was the state of those people, and We encompassed in knowledge all concerning Dhu al- Qarnayn. 91 Then followed he (another) way, 92 until he came between two mountains. He found beside them a people who could scarcely understand a word [of his language]. 93 They said, "O Dhu'l-Qarnayn! Gog and Magog are causing corruption in the land, so may we pay you tribute on condition that you set a barrier between us and them?" 94 He said: "That (wealth, authority and power) in which my Lord had established me is better (than your tribute). So help me with strength (of men), I will erect between you and them a barrier. 95 “Give me sheets of iron”; until when he had raised the wall equal to the edge of the two mountains, he said, “Blow”; to the extent that he made it ablaze – he said, “Bring me molten copper to pour upon it.” 96 Therefore Yajuj and Majuj were neither able to surmount it, nor could they pierce it. 97 He said, 'This is a mercy from my Lord. But when the promise of my Lord comes to pass, He will make it into powder; and my Lord's promise is ever 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 And We shall present Hell that day for Unbelievers to see, all spread out,- 100 (To) Those whose eyes had been under a covering from My Reminder (this Quran), and who could not bear to hear (it). 101
