18.81 . And We intended that their Lord should change him for them for one better in purity and nearer to mercy .

18.82 . And as for the wall , it belonged to two orphan boys in the city , and there was beneath it a treasure belonging to them and their father had been righteous , and thy Lord intended that they should come to their full strength and should bring forth their treasure as a mercy from their Lord ; and I did it not upon my own command . Such is the interpretation of that wherewith thou couldst not bear .

18.83 . They will ask thee of Dhul-Qarneyn . Say : I shall recite unto you a remembrance of him .

18.84 . Lo! We made him strong in the land and gave unto every thing a road .

18.85 . And he followed a road

18.86 . Till , when he reached the setting place of the sun , he found it setting in a muddy spring , and found a people thereabout : We said : O Dhul-Qarneyn! Either punish or show them kindness .

18.87 . He said : As for him who doeth wrong , we shall punish him , and then he will be brought back unto , his Lord , who will punish him with awful punishment!

18.88 . But as for him who believeth and doeth right , good will be his reward , and We shall speak unto him a mild command .

18.95 . He said : That wherein my Lord hath established me better ( than your tribute ) . Do but help me with strength ( of men ) , I will set between you and them a bank .

18.96 . Give me pieces of iron till , when he had levelled up ( the gap ) between the cliffs , he said : Blow! till , when he had made it a fire , he said : Bring me molten copper to pour thereon .

18.98 . He said : This is a mercy from my Lord ; but when the promise of my Lord cometh to pass , He will lay it low , for the promise of my Lord is true .

18.99 . And on that day We shall let some of them surge against others , and the Trumpet will be blown . Then We shall gather them together in one gathering .

18.100 . On that day We shall present hell to the disbelievers , plain to view ,
