The early history of the Seljuqs written in the Rahat al-sudur, relies heavily upon the Saljuq-nama. However, events after 1175 are directly witnessed by Rawandi since he was a member of Toghrul III's court, making the Rahat al-sudur an invaluable source for Toghrul's reign.[1] According to the Rahat al-sudur, the Seljuqs held the Ghaznavids in contempt due to their slave origins.[2]
