This story from Jami's Baharestan teaches that the reputation of a just ruler can compel obedience more powerfully than any formal instrument of authority. While personally repairing a wall in Medina, Umar receives a complaint from a Jewish man against the governor of Basra, who is delaying payment for goods bought from him. Umar writes a stern warning on a mere shard of pottery — with no royal seal and no ornamental insignia (طغرا), only his signature. Yet the dread of his justice is so deeply fixed in people's hearts that the governor, on receiving the shard, dismounts, kisses the ground, and immediately settles the debt in full.

Key idea: the moral force of just governance — its صولت عدالت (majesty of justice) and هیبت سیاست (awe of authority) — enforces compliance without external symbols of power. Justice that lives in a ruler's reputation becomes self-enforcing.
