They will ask thee of Dhu'l-Qarneyn. Say: I shall recite unto you a remembrance of him. 83 Verily We established his power on earth, and We gave him the ways and the means to all ends. 84 And he followed a road 85 Until when he reached the place where the sun set, he found it going down into a black sea, and found by it a people. We said: O Zulqarnain! either give them a chastisement or do them a benefit. 86 He said: as for him who doeth wrong, presently we shall torment him, and thereafter he shall be brought back to his Lord, and He shall torment him with a torment formidable. 87 but whoever believes and does good works shall have a good reward and We shall facilitate his matter by Our command." 88 He again pursued a purpose. 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 Thus indeed it was. We had full knowledge of him. 91 Then followed he (another) way, 92 Until, when he came between two mountains, he found before them a nation that did not appear to understand any speech. 93 They said: O Dhu'l-Qarneyn! Lo! Gog and Magog are spoiling the land. So may we pay thee tribute on condition that thou set a barrier between us and them? 94 He answered: "That wherein my Sustainer has so securely established me is better [than anything that you could give me]; hence, do but help me with [your labour's] strength, [and] I shall erect a rampart between you and them! 95 Bring me lumps of iron. Then when he had evened up between the two mountain-sides, he said: blow! Then when he had made it fire, he said: bring me and I shall pour thereon molten copper. 96 So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration. 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 will leave a part of them in conflict with another part, and the trumpet will be blown, so We will gather them all together; 99 We will fully expose the view of hell on that Day to the disbelievers, 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
