(Muhammad), they will ask you about Dhu 'l-Qarnayn. Say, "I shall tell you something about him". 83 We established him in the land, and gave him the means to achieve all things. 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 replied: 'The evildoer we shall punish. Then he shall return to his Lord and He will punish him with a stern punishment. 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 until, when he reached the rising of the sun, he found it rising upon a people for whom We had not appointed any veil to shade them from it. 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 the road, 92 Until when he reached (a place) between the two mountains, he found on that side of them a people who could hardly understand a word. 93 They said, “O Zul-Qarnain – indeed Yajuj and Majuj* are spreading chaos in the land – so shall we assign for you a consideration upon the condition that you set up a wall between us and them?” (* Gog and Magog.) 94 He replied: 'That which my Lord has given me is better, therefore help me with all your power, and I will build a barrier between you and between 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 [Ya'juj and Ma'juj (Gog and Magog)] were made powerless to scale it or dig through it. 97 Dhu al-Qarnayn said: "This is a mercy from my Lord: but when the time of my Lord's promise shall come, He will level the rampart with the ground. My Lord's promise always comes 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 set hell on that Day unto the infidels with a setting. 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
