ثُمَّ أَتۡبَعَ سَبَبًا
Then he followed another way,
حَتَّىٰٓ إِذَا بَلَغَ مَطۡلِعَ ٱلشَّمۡسِ وَجَدَهَا تَطۡلُعُ عَلَىٰ قَوۡمٖ لَّمۡ نَجۡعَل لَّهُم مِّن دُونِهَا سِتۡرٗا
Until, when he came to the rising place of the sun, he found it rising on a people for whom We (Allah) had provided no shelter against the sun.
كَذَٰلِكَۖ وَقَدۡ أَحَطۡنَا بِمَا لَدَيۡهِ خُبۡرٗا
So (it was)! And We knew all about him (Dhul-Qarnain).
ثُمَّ أَتۡبَعَ سَبَبًا
Then he followed (another) way,
حَتَّىٰٓ إِذَا بَلَغَ بَيۡنَ ٱلسَّدَّيۡنِ وَجَدَ مِن دُونِهِمَا قَوۡمٗا لَّا يَكَادُونَ يَفۡقَهُونَ قَوۡلٗا
Until, when he reached between two mountains, he found, before (near) them (those two mountains), a people who scarcely understood a word.
قَالُواْ يَٰذَا ٱلۡقَرۡنَيۡنِ إِنَّ يَأۡجُوجَ وَمَأۡجُوجَ مُفۡسِدُونَ فِي ٱلۡأَرۡضِ فَهَلۡ نَجۡعَلُ لَكَ خَرۡجًا عَلَىٰٓ أَن تَجۡعَلَ بَيۡنَنَا وَبَيۡنَهُمۡ سَدّٗا
They said: "O Dhul-Qarnain! Verily! Ya'juj and Ma'juj (Gog and Magog) are doing great mischief in the land. Shall we then pay you a tribute in order that you might erect a barrier between us and them?"
