(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 Behold, We established him securely on earth, and endowed him with [the knowledge of] the right means to achieve anything [that he might set out to achieve]; 84 He set out (westwards) on an expedition, 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 replied: 'The evildoer we shall punish. Then he shall return to his Lord and He will punish him with a stern punishment. 87 And as for him who believeth and worketh righteously, unto him shall be a goodly hire, and anon we shall speak unto him of our affair something easy. 88 He travelled again 89 Until when he reached the land of the rising of the sun, he found it rising on a people to whom We had given no shelter from It; 90 Thus. And We had encompassed [all] that he had in knowledge. 91 Then he followed (another) course. 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 Zul-Qarnain verily Yajuj and Majuj are working corruption in the land; shall we then pay thee tribute on condition that thou place between us and them a barrier! 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!' Until, when he had made all level between the two cliffs, he said, 'Blow!' Until, when he had made it a fire, he said, 'Bring me, that I may pour molten brass on it.' 96 (Thus he constructed the barrier which) neither Gog nor Magog were able to climb nor were they able to dig a tunnel through the iron and brass barrier. 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 ۞ 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 on that Day We shall place hell, for all to see, before those who denied the truth 100 Whose eyes were veiled against My warning, and they could not hear. 101
