And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 Verily We! We established him in the earth, and vouchsafed unto him of everything a way. 84 He set out (westwards) on an expedition, 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 him (a disbeliever in the Oneness of Allah) who does wrong, we shall punish him; and then he will be brought back unto his Lord; Who will punish him with a terrible torment (Hell). 87 And as for him who believeth and worketh righteously, unto him shall be a goodly hire, and anon we shall speak unto him of our affair something easy. 88 Then he followed a road 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had provided no covering protection against the sun. 90 Thus it was. And surely We have encompassed all that was with him in knowledge 91 Then he followed a way 92 when he reached between the two barriers he found on one side of them a nation who could barely understand speech. 93 They said, "O Dhu'l-Qarnayn! Gog and Magog are causing corruption in the land, so may we pay you tribute on condition that you set a barrier between us and them?" 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 ingots of iron," (which they did) until the space between two mountain sides was filled up. "Blow your bellows," he said; (and they blew) until it was red hot. "Bring me molten brass," he said, "that I may pour over it." 96 So they [Gog and Magog] were not able to scale it, nor were they able to bore 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 ۞ On that Day, We shall let them surge against each other like waves and then the Trumpet will be blown and We shall gather them all together. 99 And on that Day We shall place hell, for all to see, before those who denied the truth 100 Those whose eyes were hoodwinked from My reminder, and who could not bear to hear. 101
