And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 We established him in the land, and We gave him a way to everything; 84 And he followed a 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: "Whoever doth wrong, him shall we punish; then shall he be sent back to his Lord; and He will punish him with a punishment unheard-of (before). 87 but whoever believes and does good works shall have a good reward and We shall facilitate his matter by Our command." 88 He then followed (another) road 89 [And then he marched eastwards] till, when he came to the rising of the sun he found that it was rising on a people for whom We had provided no coverings against it: 90 Thus was the state of those people, and We encompassed in knowledge all concerning Dhu al- Qarnayn. 91 And once again he chose the right means [to achieve a right end]. 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, "Dhu 'l-Qarnayn, Gog and Magog are ravaging this land. Would you establish a barrier between us and them if we pay you a certain tax?" 94 He said: "The ability my Lord has given me is better. So help me with your manual labour; I will build a wall between you and them. 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 Dhul-Qarnain) said: "This is a mercy from my Lord, but when the Promise of my Lord comes, He shall level it down to the ground. And the Promise of my Lord is ever true." 98 ۞ On that day We shall leave them to surge like waves on one another: the trumpet will be blown, and We shall collect them all together. 99 And on that Day We shall place hell, for all to see, before those who denied the truth 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
