AND THEY will ask thee about the Two-Horned One. Say: "I will convey unto you something by which he ought to be remembered." 83 We established him in the land and gave him means to all things. 84 and he followed a way 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, "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 "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 Then followed he (another) 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 a road 92 until he came between two mountains. He found beside them a people who could scarcely understand a word [of his language]. 93 They said: "O Zul-qarnain! the Gog and Magog (People) do great mischief on earth: shall we then render thee tribute in order that thou mightest erect a barrier between us and them? 94 He said: "The ability my Lord has given me is better. So help me with your manual labour; I will build a wall between you and 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 So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration. 97 [Dhul-Qarnayn] said, "This is a mercy from my Lord; but when the promise of my Lord comes, He will make it level, and ever is the promise of my Lord true." 98 ۞ And We shall leave them on that day surging one against other and the trumpet shall be blown, and then We shall assemble them together. 99 Then We shall bring Hell right before the infidels 100 (Unbelievers) whose eyes had been under a veil from remembrance of Me, and who had been unable even to hear. 101
