And they ask you about Dhul-Qarnain. Say: "I shall recite to you something of his story." 83 We established him in the land, and gave him the means to achieve all things. 84 Then he followed 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 one who wrongs, we will punish him. Then he will be returned to his Lord, and He will punish him with a terrible 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 Then he followed yet another path, 89 [And then he marched eastwards] till, when he came to the rising of the sun he found that it was rising on a people for whom We had provided no coverings against it: 90 So, We encompassed in knowledge what was with him. 91 Then he set out on another expedition 92 until when he reached a place between the two mountains, he found beside the mountains a people who scarcely understood anything. 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 Bring me sheets of iron" - until, when he had leveled [them] between the two mountain walls, he said, "Blow [with bellows]," until when he had made it [like] fire, he said, "Bring me, that I may pour over it molten copper." 96 And thus [the rampart was built, and] their enemies were unable to scale it, and neither were they able to pierce it. 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 present Gehenna (Hell) to the unbelievers, 100 who have turned a blind eye to My reminder and a deaf ear to My warning. 101
