(Muhammad), they will ask you about Dhu 'l-Qarnayn. Say, "I shall tell you something about him". 83 We established him in the land and gave him means to all things. 84 He journeyed on a way 85 Until, when he reached the setting place of the sun, he found it setting in a spring of black muddy (or hot) water. And he found near it a people. We (Allah) said (by inspiration): "O Dhul-Qarnain! Either you punish them, or treat them with kindness." 86 He said: as for him who doeth wrong, presently we shall torment him, and thereafter he shall be brought back to his Lord, and He shall torment him with a torment formidable. 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 way 89 To the extent that when he reached the rising-place of the sun, he found it rising upon a nation for which We had not kept any shelter from it. 90 So; and We encompassed in knowledge what was with him. 91 He again pursued a purpose. 92 Until, when he reached [a pass] between two mountains, he found beside them a people who could hardly understand [his] speech. 93 They said: O Zulqarnain! surely Gog and Magog make mischief in the land. Shall we then pay you a tribute on condition that you should raise a barrier between us and them 94 He said: "(The power) in which my Lord has established me is better (than tribute): Help me therefore with strength (and labour): I will erect a strong barrier between you and them: 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 Such was the rampart that Gog and Magog could not scale, nor could they pierce it. 97 and he said, "This is a mercy from my Lord. But when the promise of my Lord comes to pass, He will level it to dust. My Lord's promise is ever true!" 98 ۞ And We shall leave them on that day surging one against other and the trumpet shall be blown, and then We shall assemble them together. 99 And on that Day We shall present Hell to the disbelievers, plain to view, 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
