(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 We established him in the land and gave him means to all things. 84 He therefore pursued a purpose. 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: "We will chastise him who does wrong, whereafter he will be returned to his Lord and He will chastise him grievously. 87 But as for one who believes and does righteousness, he will have a reward of Paradise, and we will speak to him from our command with ease." 88 He then followed (another) road 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 (He left them) as they were: We completely understood what was before him. 91 Then he followed a way 92 when he reached between the two barriers he found on one side of them a nation who could barely understand speech. 93 They said: "O Dhu al-Qarnayn, Gog and Magog are spreading corruption in this land. So shall we pay you taxes on the understanding that you will set up 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 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 Therefore Yajuj and Majuj were neither able to surmount it, nor could they pierce it. 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 ۞ And on that Day [i.e. the Day Ya'juj and Ma'juj (Gog and Magog) will come out], We shall leave them to surge like waves on one another, and the Trumpet will be blown, and We shall collect them all together. 99 And We shall bring hell in front of the disbelievers. 100 who have turned a blind eye to My reminder and a deaf ear to My warning. 101
