And they ask you, [O Muhammad], about Dhul-Qarnayn. Say, "I will recite to you about him a report." 83 Verily, We established him in the earth, and We gave him the means of everything. 84 So he followed a way 85 Till, when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a people thereabout. We said: O Dhu'l-Qarneyn! Either punish or show them kindness. 86 He said, 'As for the evildoer, him we shall chastise, then he shall be returned to his Lord and He shall chastise him with a horrible chastisement. 87 But he who believes and does the right will have an excellent reward, and we shall make things easy for him." 88 Then he followed another way, 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, We encompassed in knowledge what was with him. 91 Then followed he (another) way, 92 Till he reached a place between two mountains, and found this side of it a people who understood but little of what was spoken. 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 said: That wherein my Lord hath established me is better (than your tribute). Do but help me with strength (of men), I will set between you and them a bank. 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 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 Unto those whose eyes had been under a covering from My remembrance, nor had they been able to hear. 101
