=== Under the Umayyad rulers ===
Most Umayyad rulers are often described by Muslim historians as corrupt, irreligious, and treacherous.{{sfn|Momen|1985|p=10}} The widespread political and social dissatisfaction with the [[Umayyad Caliphate]] was spearheaded by Muhammad's extended family, who were seen by Muslims as God-inspired leaders in their religious struggle to establish justice over impiety.{{sfn|Jafri|1979|p=184}}{{sfn|Hawting|2006}}{{sfn|Dakake|2012|p=177}} Al-Sadiq's imamate extended over the latter half of the Umayyad Caliphate, which was marked by many (often Shia) revolts and eventually witnessed the violent overthrow of the Umayyads by the Abbasids, the descendants of Muhammad's paternal uncle [[Abbas ibn Abd al-Muttalib]].{{sfn|Gleave|2008}} Al-Sadiq maintained his father's policy of quietism in this period and, in particular, was not involved in the uprising of his uncle, [[Zayd ibn Ali]], who enjoyed the support of the [[Mu'tazilism|Mu'tazilites]] and the traditionalists of Medina and [[Kufa]].{{sfn|Jafri|1979|p=186}} Al-Sadiq also played no role in the Abbasid overthrow of the Umayyads.{{sfn|Gleave|2008}} His response to a request for help from [[Abu Muslim]], the [[Greater Khorasan|Khorasani]] rebel leader, was to burn his letter, saying, "This man is not one of my men, this time is not mine."{{sfn|Amir-Moezzi|1994|p=65}}{{sfn|Donaldson|1933|p=130}} At the same time, al-Sadiq did not advance his claims to the caliphate, even though he saw himself as the divinely designated leader of the Islamic community ([[Ummah|{{Transliteration|ar|umma}}]]).{{sfn|Armstrong|2002|p=57}}{{sfn|Gleave|2008}}{{sfn|Daftary|2013|p=48}} This spiritual, rather than political, imamate of al-Sadiq was accompanied by his teaching of the [[taqiya|{{Transliteration|ar|taqiya}}]] doctrine (religious dissimulation) to protect the Shia against prosecution by Sunni rulers.{{sfn|Takim|2004a}}{{sfn|Armstrong|2002|p=57}}{{sfn|Momen|1985|p=39}} In this period, al-Sadiq taught quietly in Medina and developed his considerable reputation as a scholar, according to [[Moojan Momen|Momen]].{{sfn|Momen|1985|p=38}}
