The story of Dhul-Qarnayn in Surah Al-Kahf (18:83-98) describes a just and powerful king to whom Allah granted authority. He traveled across lands, helping people and establishing justice. When faced with the corruption of Gog and Magog (Ya’juj and Ma’juj), he built a massive iron barrier to contain them.

[Dhul-Qarnayn] said, “This is a mercy from my Lord; but when the promise of my Lord comes, He will make it level, and ever is the promise of my Lord true.” (18:98)

This story highlights justice, humility, and trust in Allah in leadership and life.
