So, We encompassed in knowledge what was with him. (91)

Then he followed the road, (92)

when he reached between the two barriers he found on one side of them a nation who could barely understand speech. (93)

'ThulKarnain, ' they said, 'Look, Gog and Magog are corrupting the earth. Build for us a barrier between us and them, and we will pay you a tribute. ' (94)

He replied: 'That which my Lord has given me is better, therefore help me with all your power, and I will build a barrier between you and between them. (95)

Bring me ingots of iron. ' After he had leveled between the two cliffs, he said: 'Blow. ' And when he made it a fire, he said: 'Bring me molten copper so 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 my Lord's promise is come, He will make it dust. The promise of my Lord is true. ' (98)

On that day, We will let them surge on one another, and the Horn shall be blown, and We will gather them all together. (99)
