They will ask you about Dhu'l-Qarnayn. Say, "I will give you an account of him." 83 We established him in the land, and We gave him a way to everything; 84 He set out (westwards) on an expedition, 85 [And he marched westwards] till, when he came to the setting of the sun, it appeared to him that it was setting in a dark, turbid sea; and nearby he found a people [given to every kind of wrongdoing]. We said: "O thou Two-Horned One! Thou mayest either cause [them] to suffer or treat them with kindness!" 86 He submitted, “Regarding one who has done injustice, we shall soon punish him – he will then be brought back to his Lord, Who will punish him severely.” 87 But as for one who believes and does righteousness, he will have a reward of Paradise, and we will speak to him from our command with ease." 88 He travelled again 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 indeed it was. We had full knowledge of him. 91 Then he followed (another) way, 92 Till he reached a place between two mountains, and found this side of it a people who understood but little of what was spoken. 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, "The power that my Lord has granted me is better (than your tax). Help me with your man-power and I shall construct a barrier between you and Gog and Magog. 95 Bring me lumps of iron. Then when he had evened up between the two mountain-sides, he said: blow! Then when he had made it fire, he said: bring me and I shall pour thereon molten copper. 96 And (Gog and Magog) were not able to surmount, nor could they pierce (it). 97 He said: this is a mercy from my Lord; then when the promise of my Lord cometh, He shall make it powder, and the promise of my Lord is ever true. 98 ۞ On the day when the barrier is demolished, We will leave human beings in chaos. We will leave them like the waves of the sea striking against each other. Then the trumpet will be sounded and We will bring them all together. 99 That will be the Day We shall place Hell before the unbelievers 100 The ones whose eyes were covered from My remembrance, and who could not bear to hear Truth. 101
