They ask you about Dhu'l-Qarnain. 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 certain road 85 Till he reached the point of the setting sun, and saw it set behind a muddy lake, and near it found a people. We said: "O Dhu'l-Qarnain, you may either punish them or treat them with kindness." 86 He submitted, “Regarding one who has done injustice, we shall soon punish him – he will then be brought back to his Lord, Who will punish him severely.” 87 "But whoever believes, and works righteousness,- he shall have a goodly reward, and easy will be his task as We order it by our Command." 88 He then followed (another) road 89 until he reached the limit where the sun rises and he found it rising on a people whom We had provided no shelter from it. 90 Thus. And We had encompassed [all] that he had in knowledge. 91 Then he followed (another) course. 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, "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 replied: 'That which my Lord has given me is better, therefore help me with all your power, and I will build a barrier between you and between 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 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 cometh to pass, He will lay it low, for the promise of my Lord is 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 upon that day We shall present Gehenna to the unbelievers 100 (Unbelievers) whose eyes had been under a veil from remembrance of Me, and who had been unable even to hear. 101
