They will ask you about Dhu'l-Qarnayn. Say, "I will give you an account of him." 83 Surely We established him in the land and granted him means of access to every thing. 84 He travelled on a certain road; 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 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 again pursued a purpose. 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 This indeed was true. We knew all that he did there. 91 Thereafter he followed a way. 92 Until, when he reached between two mountains, he found, before (near) them (those two mountains), a people who scarcely understood a word. 93 They said, 'O Dhool Karnain, behold, Gog and Magog are doing corruption in the earth; so shall we assign to thee a tribute, against thy setting up a barrier between us and between 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 Bring me ingots of iron," (which they did) until the space between two mountain sides was filled up. "Blow your bellows," he said; (and they blew) until it was red hot. "Bring me molten brass," he said, "that I may pour over it." 96 Thus (Gog and Magog) could neither climb over it nor dig a hole through (the rampart). 97 He said, “This is the mercy of my Lord; then when the promise of my Lord arrives, He will blow it to bits; and my Lord’s promise is 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 And We shall bring hell in front of the disbelievers. 100 those whose eyes had been veiled against any remembrance of Me because they could not bear to listen [to the voice of truth]! 101
