the Rawandiyya

The Rawandiyya, according to al-Mas'udi, were Shi'a of the sons of al-Abbas ibn Abd al-Muttalib (may God be pleased with him), from Khurasan and elsewhere. They held that the person most entitled to the imamate after the Prophet ﷺ was al-Abbas, because he was his uncle, heir and kin. ²

Al-Mas'udi says they claimed that people had usurped his right until God returned it to them. They disowned Abu Bakr and Umar, and permitted the allegiance to Ali because he had permitted it. He says that al-Jahiz wrote a book for them on the imamate of the sons of al-Abbas. ²
