They ask you about Dhu'l-Qarnain. 83 We established him in the land and gave him means to all things. 84 With these he traveled 85 to the West where he found the sun setting into a warm source (spring) of water and a people living near by. We asked him, "Dhu 'l-Qarnayn, you may punish them or treat them with kindness?" 86 He replied, "I shall punish the unjust ones among them and then they will return to their Lord, who will punish them more sternly". 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 Then he followed another way, 89 until he reached the rising of the sun, he found it rising upon a nation for whom We provided no veil against it to shade them. 90 Even so! and We had a full knowledge of what he had. 91 Then he followed a way 92 Until, when he reached between two mountains, he found, before (near) them (those two mountains), a people who scarcely understood 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 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 bring me blocks of iron." Then, when he had filled the gap between the mountain sides [he said], "Now blow on the fire with your bellows." When the iron blocks were red with heat, he said, "Bring me molten brass to pour on them." 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 comes to pass He will make it level with the ground, and the promise of my Lord is ever true. 98 ۞ AND ON that Day" We shall [call forth all mankind and] leave them to surge like waves [that dash] against one another; and the trumpet [of judgment] will be blown, and We shall gather them all together. 99 and upon that day We shall present Gehenna to the unbelievers 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
