In around 948 'Imad al-Dawla named Rukn al-Dawla's eldest son, Fana Khusrau ('Adud al-Dawla) as his successor. In September 949 he died, and Rukn al-Dawla claimed the title of senior amir for himself. He traveled to Shiraz and stayed there for at least nine months in order to secure his son's succession there, despite the fact that the Samanids were threatening his own possessions. Mu'izz al-Dawla, meanwhile, accepted Rukn al-Dawla's position of senior amir and also sent troops to Shiraz to assist 'Adud al-Dawla.
