(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 So he followed a way 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, "We shall certainly punish him who does wrong; then he shall be brought back to his Lord who will punish him with a grievous punishment, 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 Then he followed a road 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 So, We encompassed in knowledge what was with him. 91 Then he followed a road 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 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 blocks of iron to fill up the passage between the two mountains." He told them to ply their bellows until the iron became hot as fire. Then he told them to pour on it molten brass." 96 So they [Gog and Magog] were not able to scale it, nor were they able to bore through it, 97 Said [the King]: "This is a mercy from my Sustainer! Yet when the time appointed by my Sustainer shall come, He will make this [rampart] level with the ground: and my Sustainer's promise always comes true!" 98 ۞ And on that day We will leave a part of them in conflict with another part, and the trumpet will be blown, so We will gather them all together; 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
