They will ask thee of Dhu'l-Qarneyn. Say: I shall recite unto you a remembrance of him. 83 We had given him great power in the land and all kinds of resources. 84 He therefore pursued a purpose. 85 until, when he reached the setting of the sun, he found it setting in a muddy spring, and nearby he found a nation. 'ThulKarnain' We said, 'you must either punish them or show them 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 As for those who believe and do good, they will receive virtuous rewards and We will tell them to do only what they can. 88 Then followed he (another) way, 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had provided no covering protection against the sun. 90 Even so! and We had a full knowledge of what he had. 91 Then he set out on another expedition 92 when he reached between the two barriers he found on one side of them a nation who could barely understand speech. 93 They said: "O Dhu al-Qarnayn, Gog and Magog are spreading corruption in this land. So shall we pay you taxes on the understanding that you will set up a barrier between us and them?" 94 He said, “That which my Lord has given me control over is better, therefore help me with strength – I shall set up a barrier between you and them.” 95 "Give me pieces (blocks) of iron," then, when he had filled up the gap between the two mountain-cliffs, he said: "Blow," till when he had made it (red as) fire, he said: "Bring me molten copper to pour over it." 96 So they were unable either to scale it or 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 dust; and the promise of my Lord is true." 98 ۞ On that day, We will let them surge on one another, and the Horn shall be blown, and We will gather them all together. 99 And We shall present Hell that day for Unbelievers to see, all spread out,- 100 whose eyes had been veiled against Our Quran and who were not able to hear (its recitation). 101
