They ask thee concerning Zul-qarnain. Say, "I will rehearse to you something of his story." 83 Verily We! We established him in the earth, and vouchsafed unto him of everything a way. 84 and so he chose the right means [in whatever he did]. 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: As to him who is unjust, we will chastise him, then shall he be returned to his Lord, and He will chastise him with an exemplary chastisement: 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 Thereafter he followed a way. 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had not made against it any shield. 90 So; and We encompassed in knowledge what was with him. 91 Then he followed a 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 verily Yajuj and Majuj are working corruption in the land; shall we then pay thee tribute on condition that thou place between us and them a barrier! 94 He said, "What My Lord has given me is better [than any tribute]. Help me with a force of labourers and I will erect a barrier between you and them: 95 Bring me ingots of iron." Then after he had filled up the space between the two mountain-sides, he said: "(Light a fire) and ply bellows." When he had made it (red like) fire, he said: "Bring me molten copper which I may pour on it." 96 And (Gog and Magog) were not able to surmount, nor could they pierce (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 shall let some of them surge like waves against others, and the Trumpet shall be blown. Then We shall gather them all together. 99 On that day we shall present hell to the disbelievers, plain to view, 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
