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 So he followed a way. 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 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 As for he who believes and does good works he shall receive a fine reward in recompense and we shall speak to him with a mild command' 88 He then followed (another) road 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had not made against it any shield. 90 So (it was). And We knew all concerning him. 91 Then he followed the road, 92 Until when he reached (a place) between the two mountains, he found on that side of them a people who could hardly understand a word. 93 They said, 'O Dhool Karnain, behold, Gog and Magog are doing corruption in the earth; so shall we assign to thee a tribute, against thy setting up a barrier between us and between them?' 94 He said, "What My Lord has given me is better [than any tribute]. Help me with a force of labourers and I will erect a barrier between you and them: 95 bring me blocks of iron." Then, when he had filled the gap between the mountain sides [he said], "Now blow on the fire with your bellows." When the iron blocks were red with heat, he said, "Bring me molten brass to pour on them." 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 ۞ We shall leave them on that day surging like waves pressing one against the other, and the trumpet blast will be sounded, when We shall gather them all together. 99 On that Day We shall lay Hell bare before those who deny the truth, 100 (To) Those whose eyes had been under a covering from My Reminder (this Quran), and who could not bear to hear (it). 101
