And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 We granted him power in the land and endowed him with all kinds of resources. 84 So he followed a way 85 to the West where he found the sun setting into a warm source (spring) of water and a people living near by. We asked him, "Dhu 'l-Qarnayn, you may punish them or treat them with kindness?" 86 He said: "Whoever doth wrong, him shall we punish; then shall he be sent back to his Lord; and He will punish him with a punishment unheard-of (before). 87 As for he who believes and does good works he shall receive a fine reward in recompense and we shall speak to him with a mild command' 88 And once again he chose the right means [to achieve a right end]. 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 Thus was the state of those people, and We encompassed in knowledge all concerning Dhu al- Qarnayn. 91 Then he set out on another expedition 92 Till, when he came between the two mountains, he found upon their hither side a folk that scarce could understand a saying. 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 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 So they [Ya'juj and Ma'juj (Gog and Magog)] were made powerless to scale it or dig through it. 97 He said: this is a mercy from my Lord; then when the promise of my Lord cometh, He shall make it powder, and the promise of my Lord 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 those whose eyes had been veiled against any remembrance of Me because they could not bear to listen [to the voice of truth]! 101
