They ask thee concerning Zul-qarnain. Say, "I will rehearse to you something of his story." 83 Verily, We established him in the earth, and We gave him the means of everything. 84 So he followed a certain road 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, 'As for the evildoer, him we shall chastise, then he shall be returned to his Lord and He shall chastise him with a horrible chastisement. 87 "But as for him who believes (in Allah's Oneness) and works righteousness, he shall have the best reward, (Paradise), and we (Dhul-Qarnain) shall speak unto him mild words (as instructions)." 88 He then followed (another) road 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 So, We encompassed in knowledge what was with him. 91 Then followed he (another) 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-Qarnain, Gog and Magog are oppressing the land. May we pay you some tribute so that you could build a rampart between us and them?" 94 He said, 'That wherein my Lord has established me is better; so aid me forcefully, and I will set up a rampart between you and between them. 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 Thereafter they could neither scale 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 into dust; and the promise of my Lord is 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 We shall present Hell that day for Unbelievers to see, all spread out,- 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
