They ask you about Dhu'l-Qarnain. 83 We granted him power in the land and endowed him with all kinds of resources. 84 and he followed a way 85 to the West where he found the sun setting into a warm source (spring) of water and a people living near by. We asked him, "Dhu 'l-Qarnayn, you may punish them or treat them with kindness?" 86 He said: "Whoever doth wrong, him shall we punish; then shall he be sent back to his Lord; and He will punish him with a punishment unheard-of (before). 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 Then he followed a way 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 So (it was)! And We knew all about him (Dhul-Qarnain). 91 Then he followed a way 92 after this to the middle of two mountains where he found a people who could hardly understand a single word. 93 They said, "O Dhu'l-Qarnayn! Gog and Magog are causing corruption in the land, so may we pay you tribute on condition that you set a barrier between us and them?" 94 He said: better is that wherein my Lord hath established me; so help me with might, and I shall place between you and them a rampart. 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 thus [the rampart was built, and] their enemies were unable to scale it, and neither were they able to pierce it. 97 Said [the King]: "This is a mercy from my Sustainer! Yet when the time appointed by my Sustainer shall come, He will make this [rampart] level with the ground: and my Sustainer's promise always comes 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 And We shall set hell on that Day unto the infidels with a setting. 100 (Unbelievers) whose eyes had been under a veil from remembrance of Me, and who had been unable even to hear. 101
