Depicts the inscriptions in Arabic "al-Imam" (Ali ibn Musa al-Rida), "Muhammad is the Messenger of God", "al-Ma'mun" and "Muhammad is the Messenger of God” and “He sent him with guidance and the true religion to make it victorious over every religion although those who associate others with God dislike it.”

Ali ibn Musa al-Rida (766–818), also known as Abū al-Ḥasan al-Thānī, was a descendant of the Islamic prophet Muhammad, and the eighth Imam in Twelver Shia Islam, succeeding his father, Musa al-Kazim.

Al-Rida was contemporary with the Abbasid caliphs Harun al-Rashid and his sons, al-Amin and al-Ma'mun. In a sudden departure from the established anti-Shia policy of the Abbasids, possibly to mitigate the frequent Shia revolts, al-Mamun invited al-Rida to Marv in Khorasan, his de facto capital, and designated him as heir apparent, despite the reluctance of the al-Rida who accepted the offer on the condition that he would not interfere in governmental affairs. The appointment of the Ali al-Rida by the Abbasid al-Mamun immediately invoked strong opposition, particularly among the Abbasids and Arab Sunni nationalists, who revolted and installed Ibrahim al-Mubarak, a half-brother of Harun al-Rashid, as the anti-caliph in Baghdad. Realizing the severity of the Iraqi opposition, al-Mamun and his entourage left Khorasan for Baghdad, accompanied by al-Rida. The Imam, however, died mysteriously when the party reached Tus in September 818. His death followed shortly after the assassination of al-Fadl ibn Sahl, the Persian vizier of al-Mamun, who was publicly seen as responsible for his pro-Shia policies. The caliph is often seen as responsible for both deaths, as he made concessions to the Arab party to smooth his return to Baghdad.

Depicts the inscriptions in Arabic “There is no god but God alone / He has no associate", "al Muttalib", "In the name of God, This dinar was struck in the year 199."

Muttalib ibn Abdallah ibn Malik al-Khuza'i was a son of the Abbasid general and administrator Abdallah ibn Malik al-Khuza'i. During the civil war between al-Amin and al-Ma'mun, he sided with the latter.

In 811, he administered the oath of allegiance (bay'ah) to al-Ma'mun for Mosul, and was named governor of Egypt briefly in 813 and again from 814 to 816. In 817, however, after al-Ma'mun chose the Alid Ali al-Rida as his heir, Muttalib joined the uprising in Baghdad against al-Ma'mun, and even administered the oath to the city's rival Caliph, Ibrahim ibn al-Mahdi.
