And they ask thee of Zul Qarnain. Say thou: I shall recite unto you of him some mention. 83 We established him in the land, and We gave him a way to everything; 84 He therefore pursued a purpose. 85 until, when he reached the setting of the sun, he found it setting in a muddy spring, and nearby he found a nation. 'ThulKarnain' We said, 'you must either punish them or show them kindness' 86 He said: "I shall punish whosoever is wicked. He will then be sent back to his Lord who will inflict on him a terrible punishment. 87 But as for him who believes and does righteous deeds - he will have the ultimate good [of the life to come] as his reward; and [as for us,] we shall make binding on him [only] that which is easy to fulfill." 88 Then he followed another way, 89 until, when he reached the rising of the sun, he found it rising upon a people for whom We had not appointed any veil to shade them from it. 90 So it is; and Our knowledge encompasses all that he possessed. 91 Then he set out on another expedition 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 'ThulKarnain' they said, 'Look, Gog and Magog are corrupting the earth. Build for us a barrier between us and them, and we will pay you a tribute' 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 Thus (Gog and Magog) could neither climb over it nor dig a hole through (the rampart). 97 He said: this is a mercy from my Lord; then when the promise of my Lord cometh, He shall make it powder, 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 present Gehenna (Hell) to the unbelievers, 100 (Unbelievers) whose eyes had been under a veil from remembrance of Me, and who had been unable even to hear. 101
