(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 We established him in the land, and We gave him a way to everything; 84 He journeyed on a way 85 To the extent that when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a nation there; We said, “O Zul-Qarnain – either punish them or choose kindness for them.” 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 believeth and doeth right, good will be his reward, and We shall speak unto him a mild command. 88 Thereafter he followed a way. 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 Thus it was. And surely We have encompassed all that was with him in knowledge 91 He travelled 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 thou Two-Horned One! Behold, Gog and Magog" are spoiling this land. May we, then, pay unto thee a tribute on the understanding that thou wilt erect a barrier between us and them?" 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 Give me pieces of iron - till, when he had levelled up (the gap) between the cliffs, he said: Blow! - till, when he had made it a fire, he said: Bring me molten copper to pour thereon. 96 Thereafter they could neither scale it, 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 ۞ 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 present Gehenna (Hell) to the unbelievers, 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
