The Holy Quran, Surat Al-Kahf - الكهف

آتُونِي زُبَرَ الْحَدِيدِ حَتَّى إِذَا سَاوَى بَيْنَ الصَّدَفَيْنِ قَالَ انفُخُوا حَتَّى إِذَا جَعَلَهُ نَاراً قَالَ آتُونِي أُفْرِغْ عَلَيْهِ قِطْراً

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.

قَالُوا يَا ذَا الْقَرْنَيْنِ إِنَّ يَأْجُوجَ وَمَأْجُوجَ مُفْسِدُونَ فِي الْأَرْضِ فَهَلْ نَجْعَلُ لَكَ خَرْجاً عَلَى أَن تَجْعَلَ بَيْنَنَا وَبَيْنَهُمْ سَدّاً

They said: O Dhul-Qarneyn! Lo! Gog and Magog are spoiling the land. So may we pay thee tribute on condition that thou set a barrier between us and them?

ثُمَّ أَتْبَعَ سَبَباً

Then he followed a road

حَتَّى إِذَا بَلَغَ مَطْلِعَ الشَّمْسِ وَجَدَهَا تَطْلُعُ عَلَى قَوْمٍ لَّمْ نَجْعَل لَّهُم مِّن دُونِهَا سِتْراً

Till, when he reached the rising place of the sun, he found it rising on a people for whom We had appointed no helper therefrom.

وَأَمَّا مَنْ آمَنَ وَعَمِلَ صَالِحاً فَلَهُ جَزَاء الْحُسْنَى وَسَنَقُولُ لَهُ مِنْ أَمْرِنَا يُسْراً

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

حَتَّى إِذَا بَلَغَ مَغْرِبَ الشَّمْسِ وَجَدَهَا تَغْرُبُ فِي عَيْنٍ حَمِئَةٍ وَوَجَدَ عِندَهَا قَوْماً قُلْنَا يَا ذَا الْقَرْنَيْنِ إِمَّا أَن تُعَذِّبَ وَإِمَّا أَن تَتَّخِذَ فِيهِمْ حُسْناً

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.
