They ask you about Dhu'l-Qarnain. 83 Verily We! We established him in the earth, and vouchsafed unto him of everything a way. 84 So he followed a course. 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 answered: "As for him who does wrong [unto others] - him shall we, in time, cause to suffer; and thereupon he shall be referred to his Sustainer, and He will cause him to suffer with unnameable suffering. 87 "But whoever believes, and works righteousness,- he shall have a goodly reward, and easy will be his task as We order it by our Command." 88 He travelled again 89 To the extent that when he reached the rising-place of the sun, he found it rising upon a nation for which We had not kept any shelter from it. 90 Thus it was. And surely We have encompassed all that was with him in knowledge 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 They said: O Dhu'l-Qarneyn! Lo! Gog and Magog are spoiling the land. So may we pay thee tribute on condition that thou set a barrier between us and 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 blocks of iron to fill up the passage between the two mountains." He told them to ply their bellows until the iron became hot as fire. Then he told them to pour on it molten brass." 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; but when the promise of my Lord cometh to pass, He will lay it low, for the promise of my Lord is 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 and upon that day We shall present Gehenna to the unbelievers 100 Whose eyes were veiled against My warning, and they could not hear. 101
