Al-Kahf 18:91

وَأَمَّا مَنْ آمَنَ وَعَمِلَ صَالِحًا فَلَهُ جَزَاءً الْحُسْنَىٰ ۖ وَسَنَقُولُ لَهُ مِنْ أَمْرِنَا يُسْرًا

But as for one who believes and does righteousness, he will have a reward of Paradise, and we will speak to him from our command with ease."

ثُمَّ أَتْبَعَ سَبَبًا

Then he followed a way

حَتَّىٰ إِذَا بَلَغَ مَطْلِعَ الشَّمْسِ وَجَدَهَا تَطْلُعُ عَلَىٰ قَوْمٍ لَّمْ نَجْعَل لَّهُم مِّن دُونِهَا سِتْرًا

Until, when he came to the rising of the sun, he found it rising on a people for whom We had not made against it any shield.

ثُمَّ أَتْبَعَ سَبَبًا

Then he followed a way

حَتَّىٰ إِذَا بَلَغَ بَيْنَ السَّدَّيْنِ وَجَدَ مِن دُونِهِمَا قَوْمًا لَّا يَكَادُونَ يَفْقَهُونَ قَوْلًا

Until, when he reached [a pass] between two mountains, he found beside them a people who could hardly understand [his] speech.

قَالُوا يَا ذَا الْقَرْنَيْنِ إِنَّ يَأْجُوجَ وَمَأْجُوجَ مُفْسِدُونَ فِي الْأَرْضِ فَهَلْ نَجْعَلُ لَكَ خَرْجًا عَلَىٰ أَن تَجْعَلَ بَيْنَنَا وَبَيْنَهُمْ سَدًّا

They said, "O Dhul-Qarnayn, indeed Gog and Magog are [great] corrupters in the land. So may we assign for you an expenditure that you might make between us and them a barrier?"
