Duty of a Governer

During the Caliphate of Hadhrat Ali (a.s.), once a governor was invited to a feast. The governor accepted the invitation and participated in the party. When Hadhrat Ali (a.s.) came to know about this he reprimanded the governor severely saying: “Entertaining a governor is bribe. Why was this bribe given? If it was given to establish a right it is the duty of a governor to give the entitled persons their right without taking bribe, or this bribe was given to validate something invalid. If that be the case it is not lawful for a governor to do any such thing even though the entire world may be offered to him as bribe.
The second thing is: Why did the governor participate in a feast to which the rich were invited but the indigent were ignored and thus a discrimination was made between the slaves of Allah? This discrimination pained many persons and also grieved Ali. Of course if the society is prosperous and the people are well-to-do there is no harm in inviting only some persons to a party to the exclusion of others. However, when the conditions are such that there are poor as well as rich persons in the society, does the extension of an invitation to a governor to participate in a feast not amount to giving him bribe?
