They will ask thee of Dhu'l-Qarneyn. Say: I shall recite unto you a remembrance of him. 83 Indeed We established him upon the earth, and We gave him to everything a way. 84 So he followed a way 85 Until, when he reached the setting of the sun, he found it set in a spring of murky water: Near it he found a People: We said: "O Zul-qarnain! (thou hast authority,) either to punish them, or to treat them with kindness." 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 But as for him who believeth and doeth right, good will be his reward, and We shall speak unto him a mild command. 88 Then he followed (another) course. 89 Till he reached the point of the rising sun, and saw it rise over a people for whom We had provided no shelter against it. 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 He again pursued a purpose. 92 Till, when he came between the two mountains, he found upon their hither side a folk that scarce could understand a saying. 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: "Whatever my Lord has granted me is good enough. But help me with your labour and I will erect a rampart between you and them. 95 "Give me pieces (blocks) of iron," then, when he had filled up the gap between the two mountain-cliffs, he said: "Blow," till when he had made it (red as) fire, he said: "Bring me molten copper to pour over it." 96 (Thus he constructed the barrier which) neither Gog nor Magog were able to climb nor were they able to dig a tunnel through the iron and brass barrier. 97 He said, “This is the mercy of my Lord; then when the promise of my Lord arrives, He will blow it to bits; and my Lord’s promise 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 And We shall set hell on that Day unto the infidels with a setting. 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
