(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 We granted him power in the land and endowed him with all kinds of resources. 84 So he followed a way. 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 one who wrongs, we will punish him. Then he will be returned to his Lord, and He will punish him with a terrible punishment. 87 As for those who believe and do good, they will receive virtuous rewards and We will tell them to do only what they can. 88 And once again he chose the right means [to achieve a right end]. 89 Until, when he came to the rising place of the sun, he found it rising on a people for whom We (Allah) had provided no shelter against the sun. 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 Then followed he (another) way, 92 [And he marched on] till, when he reached [a place] between the two mountain-barriers, he found beneath them a people who could scarcely understand a word [of his language]. 93 They said, 'O Dhool Karnain, behold, Gog and Magog are doing corruption in the earth; so shall we assign to thee a tribute, against thy setting up a barrier between us and between them?' 94 He answered: "That wherein my Sustainer has so securely established me is better [than anything that you could give me]; hence, do but help me with [your labour's] strength, [and] I shall erect a rampart between you and them! 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 And (Gog and Magog) were not able to surmount, nor could they pierce (it). 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 ۞ And We will leave them that day surging over each other, and [then] the Horn will be blown, and We will assemble them in [one] assembly. 99 On that Day We shall present Gehenna (Hell) to the unbelievers, 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
