الكهف — Al-Kahf Ayat 94
قَالُوْا يٰذَا الْقَرْنَيْنِ اِنَّ يَأْجُوْجَ وَمَأْجُوْجَ مُفْسِدُوْنَ فِى الْاَرْضِ فَهَلْ نَجْعَلُ لَكَ خَرْجًا عَلٰٓى اَنْ تَجْعَلَ بَيْنَنَا وَبَيْنَهُمْ سَدًّا
Qālū yā żal-qarnaini inna ya'jūja wa ma'jūja mufsidūna fil-arḍi fahal naj‘alu laka kharjan ‘alā an taj‘alā bainanā wa bainahum saddā(n).
"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?""
