عضد الدولة
In January of 976 Rukn al-Dawla met with his eldest son, 'Adud al-Dawla, who ruled in Fars. 'Adud al-Dawla consented to Rukn al-Dawla's request that Fakhr al-Dawla be made the ruler of Ray upon his death, while Hamadan would go to a third son, Mu'ayyad al-Dawla, in exchange for a promise that both of them would recognize him as senior amir. Only eight months later, Rukn al-Dawla died and Fakhr al-Dawla succeeded him in Ray, and shortly had his cousin Ali ibn Kama executed.
