And they ask you about Dhul-Qarnain. Say: "I shall recite to you something of his story." 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 So he followed a course. 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 said: "As for him (a disbeliever in the Oneness of Allah) who does wrong, we shall punish him; and then he will be brought back unto his Lord; Who will punish him with a terrible torment (Hell). 87 But he who believes and does the right will have an excellent reward, and we shall make things easy for him." 88 He travelled again 89 until he reached the limit where the sun rises and he found it rising on a people whom We had provided no shelter from it. 90 Thus it was. And surely We have encompassed all that was with him in knowledge 91 Then followed he (another) way, 92 Until when he arrived between the two mountains, he found beside them a people who well-nigh understood not a word. 93 They said, "Dhu 'l-Qarnayn, Gog and Magog are ravaging this land. Would you establish a barrier between us and them if we pay you a certain tax?" 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 "Bring me blocks of iron." At length, when he had filled up the space between the two steep mountain-sides, He said, "Blow (with your bellows)" Then, when he had made it (red) as fire, he said: "Bring me, that I may pour over it, molten lead." 96 And (Gog and Magog) were not able to surmount, 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 ۞ 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 That will be the Day We shall place Hell before the unbelievers 100 Unto those whose eyes had been under a covering from My remembrance, nor had they been able to hear. 101
