True leadership is marked by justice, humility, and service to others, as exemplified by Dhul-Qarnayn in Surah al-Kahf (18:83–98). Allah gave him power and authority, yet he used it not for tyranny, but to establish justice and protect the oppressed. 

When he reached a people who were vulnerable to the destruction of Gog and Magog, he listened to their plea and cooperated with them to build a strong barrier—not for fame, but to fulfill a responsibility. 

He acknowledged that all success was from Allah, saying, “This is a mercy from my Lord” (18:98), showing that true leaders remain grounded, give credit to God, and act with wisdom and compassion.
