Muhammad ibn Ali Rawandi (Persian: محمد بن علی راوندی; died after 1207), was a Persian[1] historian who wrote the Rahat al-sudur wa ayat al-surur during the fall of the Great Seljuk Empire and the subsequent invasion by the Kharwarzmian empire.
He was from a scholarly family from Rawand near Kashan, and studied Hanafi fiqh in Hamadan from 1174 to 1184.
[1] As a calligrapher, Rawandi was brought to court to craft a Quran for Toghrul III and gained the sultan's favor.
After Toghrul's incarceration, Rawandi gained the patronage of Shihab al-Din al-Kashani, who urged him to write the Rahat al-sudur.
Later the Rahat al-sudur was translated into Turkish during the reign of Murad II.
