Abbasid, Al-Ma’mun (AH 196-218 / 812-833 AD), silver Dirham, AH 204 / 819 AD, Isfahan, citing the Imam Ali b. Musa al-Rida and vizier Dhu’l-Riyasatayn, 2.88g (A. 224). Very Fine, slight wave to the flan, rare.
Caliph al-Ma’mun brought Imam al-Rida to Khorasan by force and despite Imam’s will made him a crown prince. The debate sessions al-Ma’mun and Imam al-Rida and personalities of other religions and schools of thought are famous. The appointment of al-Rida as prince is representing al-Ma’mun’s attempt to establish peace and cooperation between the Sunni and Shi’a branches of Islam. However, he had fallen out of favour with the Caliph and was subsequently martyred.
