Quran 18:93 — The Cave (Al-Kahf)

When he reached the valley between two palisades, he found people whose language was barely understandable.

[18:92] He then pursued another way.

[18:94] They said, "O Zul-Qarnain, Gog and Magog are corruptors of the earth. Can we pay you to create a barrier between us and them?"
