And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 Surely We established him in the land and granted him means of access to every thing. 84 and so he chose the right means [in whatever he did]. 85 until, when he reached the setting of the sun, he found it setting in a muddy spring, and he found nearby a people. We said, 'O Dhool Karnain, either thou shalt chastise them, or thou shalt take towards them a way of kindness.' 86 He said: As for him who doeth wrong, we shall punish him, and then he will be brought back unto his Lord, Who will punish him with awful punishment! 87 But as for him who believeth and doeth right, good will be his reward, and We shall speak unto him a mild command. 88 He travelled again 89 Until when he reached the rising place of the sun, he perceived it rising upon a nation for whom against it We had not set a veil. 90 Thus. And We had encompassed [all] that he had in knowledge. 91 Then he followed a road 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 Dhul-Qarnain! Verily! Ya'juj and Ma'juj (Gog and Magog) are doing great mischief in the land. Shall we then pay you a tribute in order that you might erect 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 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 Such was the rampart that Gog and Magog could not scale, nor could they pierce it. 97 Dhu l-Qarnayn said, "This barrier is a blessing from my Lord but when His promise comes to pass He will level it to the ground; His promise always comes true." 98 ۞ On the day when the barrier is demolished, We will leave human beings in chaos. We will leave them like the waves of the sea striking against each other. Then the trumpet will be sounded and We will bring them all together. 99 and upon that day We shall present Gehenna to the unbelievers 100 who have turned a blind eye to My reminder and a deaf ear to My warning. 101
