(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 He set out (westwards) on an expedition, 85 Until, when he reached the setting of the sun, he found it set in a spring of murky water: Near it he found a People: We said: "O Zul-qarnain! (thou hast authority,) either to punish them, or to treat them with kindness." 86 He said: As for him who doeth wrong, we shall punish him, and then he will be brought back unto his Lord, Who will punish him with awful 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 set out on another expedition 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 Even so! and We had a full knowledge of what he had. 91 He again pursued a purpose. 92 Until when he arrived between the two mountains, he found beside them a people who well-nigh understood not 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 Bring me ingots of iron' After he had leveled between the two cliffs, he said: 'Blow' And when he made it a fire, he said: 'Bring me molten copper so that I may pour over it' 96 (Thus he constructed the barrier which) neither Gog nor Magog were able to climb nor were they able to dig a tunnel through the iron and brass barrier. 97 He said: 'This is a mercy from my Lord. But when my Lord's promise is come, He will make it dust. The promise of my Lord is true' 98 ۞ AND ON that Day" We shall [call forth all mankind and] leave them to surge like waves [that dash] against one another; and the trumpet [of judgment] will be blown, and We shall gather them all together. 99 On that Day We shall lay Hell bare before those who deny the truth, 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
