They will ask you about ThulKarnain (the pious and chosen). Say: 'I will recite to you something of his story. 83 Say: "I will cite before you his commemoration." We gave him authority in the land and means of accomplishing every end. 84 He therefore pursued a purpose. 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 said, "As for one who wrongs, we will punish him. Then he will be returned to his Lord, and He will punish him with a terrible punishment. 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 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 So it is; and Our knowledge encompasses all that he possessed. 91 Then he followed (another) way, 92 Until, when he reached [a pass] between two mountains, he found beside them a people who could hardly understand [his] speech. 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: 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 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 Said [the King]: "This is a mercy from my Sustainer! Yet when the time appointed by my Sustainer shall come, He will make this [rampart] level with the ground: and my Sustainer's promise always comes true!" 98 ۞ On that day, We will let them surge on one another, and the Horn shall be blown, and We will gather them all together. 99 That will be the Day We shall place Hell before the unbelievers 100 who have turned a blind eye to My reminder and a deaf ear to My warning. 101
