This concept explores the anecdote of Caliph Umar and young Abdullah ibn al-Zubayr in Sana'i's Hadiqat al-Haqiqah. When Umar passes by a group of playing children, all of them run away in awe of his presence except for Abdullah. When asked why he did not flee, Abdullah replies that since Umar is just and he is not a wrongdoer, he has no reason to fear. The tale illustrates the philosophical idea that a person secure in their own innocence and self-knowledge (knowing their own essence or 'جوهر خود') remains fearless in the presence of authority. It also emphasizes that a just and pious ruler inspires peace and security, rather than dread, among innocent subjects.
