Fakhr al-Daula died in 997; his elder son Abu Taleb Rostam ("Majd al-Daula") took power in the bulk of his father's possessions in Jibal.

Since both sons were still minors their mother, the "Sayyida", assumed the regency.
Both sons originally took the title of Shâhanshâh, implying that they were subordinate to no one. Shah is an Iranian term for a Monarch (leader that has been adopted in many other languages They abandoned the title, however, when they accepted their cousin Baha al-Daula's authority by 1009 or 1010 at the latest.

Their forces laid siege to Ray and fought several battles with Majd al-Daula's forces. See Rayshahr for the Sassanid center of learning in Fars province When Ray was finally taken, Majd al-Daula was imprisoned for a year, and Shams al-Daula ruled in the city during that time. When the Sayyida released Majd al-Daula, Shams al-Daula returned to Hamadan.
Around 1013, following the death of the Badr ibn Hasanwaih, Shams al-Daula occupied part of the former ruler's territory. Sometime in the later part of his reign, he tried to replace Majd al-Daula as the ruler of Ray, but the Sayyida foiled his plans. He died in 1021 and was succeeded by his son Sama' al-Daula. Sama' al-Daula was the Buyid ruler of Hamadan ( 1021 - 1023 or 1024)
