And they ask you about Dhul-Qarnain. Say: "I shall recite to you something of his story." 83 Behold, We established him securely on earth, and endowed him with [the knowledge of] the right means to achieve anything [that he might set out to achieve]; 84 So he followed 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 submitted, “Regarding one who has done injustice, we shall soon punish him – he will then be brought back to his Lord, Who will punish him severely.” 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 Then he set out on another expedition 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 thus [We had made them, and thus he left them; and We did encompass with Our knowledge all that he had in mind 91 Then he followed (another) course. 92 Until, when he reached (a tract) between two mountains, he found, beneath them, a people who scarcely understood a word. 93 They said: "O Dhu al-Qarnayn, Gog and Magog are spreading corruption in this land. So shall we pay you taxes on the understanding that you will set up 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 (blocks) of iron," then, when he had filled up the gap between the two mountain-cliffs, he said: "Blow," till when he had made it (red as) fire, he said: "Bring me molten copper to pour over it." 96 So they were unable either to scale it or pierce it. 97 He said: This is a mercy from my Lord; but when the promise of my Lord cometh to pass, He will lay it low, for the promise of my Lord is true. 98 ۞ On that day, We will let them surge on one another, and the Horn shall be blown, and We will gather them all together. 99 We will fully expose the view of hell on that Day to the disbelievers, 100 (To) Those whose eyes had been under a covering from My Reminder (this Quran), and who could not bear to hear (it). 101
