(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 the means to achieve all things. 84 Then he followed a way. 85 Until, when he reached the setting of the sun, he found it [as if] setting in a spring of dark mud, and he found near it a people. Allah said, "O Dhul-Qarnayn, either you punish [them] or else adopt among them [a way of] goodness." 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 And as for him who believeth and worketh righteously, unto him shall be a goodly hire, and anon we shall speak unto him of our affair something easy. 88 He again pursued a purpose. 89 Until when he reached the rising place of the sun, he perceived it rising upon a nation for whom against it We had not set a veil. 90 So it is; and Our knowledge encompasses all that he possessed. 91 And once again he chose the right means [to achieve a right end]. 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 Zul-Qarnain verily Yajuj and Majuj are working corruption in the land; shall we then pay thee tribute on condition that thou place between us and them a barrier! 94 He answered: "Whatever my Lord has granted me is good enough. But help me with your labour and I will erect a rampart between you and them. 95 Bring me ingots of iron." Then after he had filled up the space between the two mountain-sides, he said: "(Light a fire) and ply bellows." When he had made it (red like) fire, he said: "Bring me molten copper which I may pour on it." 96 So they [Ya'juj and Ma'juj (Gog and Magog)] were made powerless to scale it or dig through 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 on that Day We shall let some of them surge like waves against others, and the Trumpet shall be blown. Then We shall gather them all together. 99 And We shall bring hell in front of the disbelievers. 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
