(Muhammad), they will ask you about Dhu 'l-Qarnayn. Say, "I shall tell you something about him". 83 We had given him great power in the land and all kinds of resources. 84 With these he traveled 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: "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 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 Then followed he (another) way, 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 So; and We encompassed in knowledge what was with him. 91 And once again he chose the right means [to achieve a right end]. 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 thou Two-Horned One! Behold, Gog and Magog" are spoiling this land. May we, then, pay unto thee a tribute on the understanding that thou wilt erect a barrier between us and them?" 94 He said: That in which my Lord has established me is better, therefore you only help me with workers, I will make a fortified barrier between you and them; 95 Bring me ingots of iron!" Then, after he had [piled up the iron and] filled the gap between the two mountain-sides, he said: "[Light a fire and] ply your bellows!" At length, when he had made it [glow like] fire, he commanded: "Bring me molten copper which I may pour upon it." 96 So they [Ya'juj and Ma'juj (Gog and Magog)] were made powerless to scale it or dig through it. 97 He said: This is a mercy from my Lord, but when the promise of my Lord comes to pass He will make it level with the ground, and the promise of my Lord is ever true. 98 ۞ On that day, We will let them surge on one another, and the Horn shall be blown, and We will gather them all together. 99 On that Day We shall present Gehenna (Hell) to the unbelievers, 100 who have turned a blind eye to My reminder and a deaf ear to My warning. 101
