(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 Verily We established his power on earth, and We gave him the ways and the means to all ends. 84 So he followed a way 85 until, when he reached the setting of the sun, he found it setting in a spring of murky water and near it he found some people. We said, "Dhu'l-Qarnayn! You can either punish them or else you can treat them with gentleness." 86 He answered: "As for him who does wrong [unto others] - him shall we, in time, cause to suffer; and thereupon he shall be referred to his Sustainer, and He will cause him to suffer with unnameable suffering. 87 but whoever believes and does good works shall have a good reward and We shall facilitate his matter by Our command." 88 Then he followed a way 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had not made against it any shield. 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 Then he followed a way 92 after this to the middle of two mountains where he found a people who could hardly understand a single word. 93 They said, "O Dhu'l-Qarnayn! Gog and Magog are causing corruption in the land, so may we pay you tribute on condition that you set a barrier between us and them?" 94 He said: better is that wherein my Lord hath established me; so help me with might, and I shall place between you and them a rampart. 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 Thus (Gog and Magog) could neither climb over it nor dig a hole through (the rampart). 97 He said: "This is a mercy from my Lord: But when the promise of my Lord comes to pass, He will make it into dust; and the promise of my Lord is true." 98 ۞ And on that day We shall release them in groups surging like waves one after another, and the Trumpet will be blown – so We shall gather them all together. (* Gog and Magog will come out during the time of Eisa (Jesus – when he comes back to earth) and cause great destruction in the land.) 99 and upon that day We shall present Gehenna to the unbelievers 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
