They will question thee concerning Dhool Karnain. Say: 'I will recite to you a mention of him. 83 We granted him power in the land and endowed him with all kinds of resources. 84 He set out (westwards) on an expedition, 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 answered: "As for him who does wrong [unto others] - him shall we, in time, cause to suffer; and thereupon he shall be referred to his Sustainer, and He will cause him to suffer with unnameable suffering. 87 And as for him who believes and does good, he shall have goodly reward, and We will speak to him an easy word of Our command. 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 And once again he chose the right means [to achieve a right end]. 92 until he came between two mountains. He found beside them a people who could scarcely understand a word [of his language]. 93 They said: 'O Dhu'l-Qarnain, Gog and Magog are oppressing the land. May we pay you some tribute so that you could build a rampart between us and them?" 94 He said, "That in which my Lord has established me is better [than what you offer], but assist me with strength; I will make between you and them a dam. 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 Thus they were not able to mount it, nor were they able to burrow through it. 97 Dhu l-Qarnayn said, "This barrier is a blessing from my Lord but when His promise comes to pass He will level it to the ground; His promise always comes true." 98 ۞ And We will leave them that day surging over each other, and [then] the Horn will be blown, and We will assemble them in [one] assembly. 99 That will be the Day We shall place Hell before the unbelievers 100 Those whose eyes were hoodwinked from My reminder, and who could not bear to hear. 101
