And they ask you regarding Zul-Qarnain; say, “I shall recite his story to you.” 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 and 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: "We will chastise him who does wrong, whereafter he will be returned to his Lord and He will chastise him grievously. 87 "But as for him who believes (in Allah's Oneness) and works righteousness, he shall have the best reward, (Paradise), and we (Dhul-Qarnain) shall speak unto him mild words (as instructions)." 88 Then he followed (another) course. 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 He then followed (another) road 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 Dhul-Qarnayn, indeed Gog and Magog are [great] corrupters in the land. So may we assign for you an expenditure that you might make between us and them a barrier?" 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." 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 were unable either to scale it or pierce it. 97 "This is the benevolence of my Lord," he said; "but when the promise of my Lord comes to pass, He will reduce it to a mound of dust; and 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 and upon that day We shall present Gehenna to the unbelievers 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
