And they ask you, [O Muhammad], about Dhul-Qarnayn. Say, "I will recite to you about him a report." 83 Say: "I will cite before you his commemoration." We gave him authority in the land and means of accomplishing every end. 84 So he followed a certain road 85 Until when he reached the place where the sun set, he found it going down into a black sea, and found by it a people. We said: O Zulqarnain! either give them a chastisement or do them a benefit. 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 And as for him who believeth and worketh righteously, unto him shall be a goodly hire, and anon we shall speak unto him of our affair something easy. 88 Then he followed a way 89 Until when he reached the land of the rising of the sun, he found it rising on a people to whom We had given no shelter from It; 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 Then he followed a way 92 Until, when he reached (a tract) between two mountains, he found, beneath them, a people who scarcely understood a word. 93 They said, "O Dhu'l-Qarnayn! Gog and Magog are causing corruption in the land, so may we pay you tribute on condition that you set a barrier between us and them?" 94 He said: That wherein my Lord hath established me is better (than your tribute). Do but help me with strength (of men), I will set between you and them a bank. 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 Thereafter they could neither scale it, 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 On that Day We shall lay Hell bare before those who deny the truth, 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
