(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 Say: "I will cite before you his commemoration." We gave him authority in the land and means of accomplishing every end. 84 So he followed a course. 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 replied: 'The evildoer we shall punish. Then he shall return to his Lord and He will punish him with a stern punishment. 87 “And regarding one who believed and did good deeds – so his reward is goodness; and we shall soon give him an easy command.” 88 Then he followed another way, 89 until he came to the rising-place of the sun, where he found it rising on a people for whom We had provided no shelter from it. 90 Thus. And We had encompassed [all] that he had in knowledge. 91 He again pursued a purpose. 92 after this to the middle of two mountains where he found a people who could hardly understand a single word. 93 They said, "Dhu 'l-Qarnayn, Gog and Magog are ravaging this land. Would you establish a barrier between us and them if we pay you a certain tax?" 94 He said: That in which my Lord has established me is better, therefore you only help me with workers, I will make a fortified barrier between you and them; 95 "Bring me blocks of iron." At length, when he had filled up the space between the two steep mountain-sides, He said, "Blow (with your bellows)" Then, when he had made it (red) as fire, he said: "Bring me, that I may pour over it, molten lead." 96 So they [Ya'juj and Ma'juj (Gog and Magog)] were made powerless to scale it or dig through it. 97 Dhul-Qarnain) said: "This is a mercy from my Lord, but when the Promise of my Lord comes, He shall level it down to the ground. And the Promise of my Lord is ever true." 98 ۞ On that day We shall leave them to surge like waves on one another: the trumpet will be blown, and We shall collect them all together. 99 and upon that day We shall present Gehenna to the unbelievers 100 who have turned a blind eye to My reminder and a deaf ear to My warning. 101
