And they ask you regarding Zul-Qarnain; say, “I shall recite his story to you.” 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 So he followed a course. 85 Until when he reached the setting-place of the sun, he perceived it setting in a miry spring, and he found beside it a nation. We said: Zul Qarnian! either chastise them or take in respect of them the way of kindness. 86 He said, "We shall certainly punish him who does wrong; then he shall be brought back to his Lord who will punish him with a grievous punishment, 87 And as for him who believes and does good, he shall have goodly reward, and We will speak to him an easy word of Our command. 88 Then he followed a way 89 Till he reached the point of the rising sun, and saw it rise over a people for whom We had provided no shelter against it. 90 So; and We encompassed in knowledge what was with him. 91 Then he followed the road, 92 Till he reached a place between two mountains, and found this side of it a people who understood but little of what was spoken. 93 They said, “O Zul-Qarnain – indeed Yajuj and Majuj* are spreading chaos in the land – so shall we assign for you a consideration upon the condition that you set up a wall between us and them?” (* Gog and Magog.) 94 He answered: "Whatever my Lord has granted me is good enough. But help me with your labour and I will erect a rampart between you and them. 95 Bring me blocks of iron; until when he had filled up the space between the two mountain sides, he said: Blow, until when he had made it (as) fire, he said: Bring me molten brass which I may pour over it. 96 And (Gog and Magog) were not able to surmount, 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 that day, We will let them surge on one another, and the Horn shall be blown, and We will gather them all together. 99 That will be the Day We shall place Hell before the unbelievers 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
