In Jami's Haft Awrang (specifically in Silsilat al-Dhahab), the tale of Sultan Ya'qub's punishment of the oppressive tax collector of Shiraz illustrates the theme of ruler responsibility and administrative justice.

Key elements of this concept include:

• Protection of Subjects (Ra'iyyah): The ruler is depicted as the ultimate protector of the common people against the tyranny of local provincial administrators and tax collectors ('awan).
• Direct Intervention: When a petition (ruq'ah) from Shiraz reaches the court of Tabriz detailing the oppression, Sultan Ya'qub does not ignore it; he directly summons the corrupt official to the capital for investigation and retribution.
• The Ruler as a Shadow of Justice: By actively suppressing local tyrants, the ruler's reputation is compared to legendary models of justice, such as Nushirvan, reinforcing the idea that a stable and legitimate dynasty depends on the eradication of corruption and injustice.
