They will ask you about Dhu'l-Qarnayn. Say, "I will give you an account of him." 83 Verily We established his power on earth, and We gave him the ways and the means to all ends. 84 He therefore pursued a purpose. 85 [And he marched westwards] till, when he came to the setting of the sun, it appeared to him that it was setting in a dark, turbid sea; and nearby he found a people [given to every kind of wrongdoing]. We said: "O thou Two-Horned One! Thou mayest either cause [them] to suffer or treat them with 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 But he who believes and does the right will have an excellent reward, and we shall make things easy for him." 88 Thereafter he followed a way. 89 Until, when he came to the rising place of the sun, he found it rising on a people for whom We (Allah) had provided no shelter against the sun. 90 Thus. And We had encompassed [all] that he had in knowledge. 91 Then followed he (another) way, 92 Until, when he reached (a tract) between two mountains, he found, beneath them, a people who scarcely understood a word. 93 They said: "O Dhul-Qarnain! Verily! Ya'juj and Ma'juj (Gog and Magog) are doing great mischief in the land. Shall we then pay you a tribute in order that you might erect a barrier between us and them?" 94 He said: That in which my Lord has established me is better, therefore you only help me with workers, I will make a fortified barrier between you and them; 95 “Give me sheets of iron”; until when he had raised the wall equal to the edge of the two mountains, he said, “Blow”; to the extent that he made it ablaze – he said, “Bring me molten copper to pour upon it.” 96 So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration. 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 (To) Those whose eyes had been under a covering from My Reminder (this Quran), and who could not bear to hear (it). 101
