Ali issued the following instructions to Abdullah b Abbas, the Governor of Basra: "You should know that Basra is the place where Satan descends. It is the home of dissension. You should treat the people of Basra with kindness and remove fear from their hearts. I have come to know that you are oppressing the people of Bani Tamim. Bani Tamim are the people whose one star rises if another star sets. That was the case both in the time of ignorance and Islam. We are also closely related to them. It behooves us to strengthen those bonds. In your speech and your actions be careful and discern the right from the wrong. You are my nominee, and I am responsible for your action. I repose confidence in you, see that this confidence is not betrayed."
