At the time of the conquest, Muslims offered border guards or local rulers several options: either become Muslims and be part of the Muslim Ummah; Or accept the rule of the Muslims and remain free by paying the Jizya and remain in their religion; Or to resist and fight as a last resort, in which case there was a risk of being killed or enslaved.[9] Arabs usually did not interfere in the internal affairs of local people who paid their taxes.[10]
The two main policies in this period were (1) to prevent the Bedouins from harming the agricultural community (2) to cooperate Muslim rulers with the rulers and notables of the conquered areas and the local people not to be disturbed as much as possible. For these reasons, the first group of Muslims did not make attempt to convert Iranians to Islam (according to Lapidus, at the time of the Arab conquest, Islam was considered as an Arab religion and for themselves) and were not interested in disrupting social and administrative order. But over time, they increased their control over the cities.[11]
The Umayyads tried to impose the Arabic language on the people under their command. For example, Al-Hajjaj ibn Yusuf, who was dissatisfied with the use of Persian language in administrative tribunals, ordered that the language be replaced by Arabic, which was usually not easy to do and was often violent.[21] The report of violence perpetrated by the Umayyads against Iranian culture is reflected in the writings of thinkers such as Abu Rihan al-Biruni and Abu al-Faraj al-Isfahani.[22] In the report on the forgetting of Khwarezmian language, Al-Biruni says that the Arab army killed all those who could speak Khwarezmian, leaving only those who could not read and write.[23]
These violent policies against the Iranians can be seen in historical sources until the time before the rise of Abbasid Caliphate. For example, the caliph's envoy in Isfahanbeheaded every single patron who failed to pay his taxes. Or, for example, historical sources such as The Complete History written by Ali ibn al-Athir have reported that Sa'id ibn al-As killed all the people of Tammisha except for one person in 651 (during the conquest of Gurgan by the Muslims during the Rashidun caliphate).[24][25]
The Arab domination over the Iranians was getting heavier and heavier, and the meaning of the Arab religion was replaced with the personal intentions and the rule of the dominant ethnic group over the defeated ethnic group and humiliation of the non-Arab people was getting acute and no progress was made for the natives.[26] There were three groups of people at this time:
A group that accepted the teachings of Islam with full will and faith and converted to Islam, which were mostly followers of the family of Ali ibn Abi Talib. This group was depressed and dissatisfied with the non-implementation of the laws and teachings of the religion.[27]
The other group, who pretended to be Muslims due to evasion of paying Jizya and Kharaj and gaining prestige and comfort, were in fact neither of the previous religion nor of the new religion. These groups were not treated as they wished, the Arabs treated them with arrogance and swagger, and did not give them social privileges as they wanted, and these caused them dissatisfaction.[27]
Others remained in the religion of their ancestors. The third group was constantly waiting for the opportunity to get rid of the rulers.[28]
Due to Al-Mutawakkil (the 10th Abbasid caliph) administrative, financial and military policies, including excessive spending, instability of administrative officials and relocation of the capital to Samarra, as well as his religious turn to the Hanbali, the caliphate was weakened and with his assassination by Turk slaves in 861 CE, the ground for the decline of Abbasid power was provided.[citation needed] With the civil war in Baghdad and Samarra over a decade after Al-Mutawakkil's death, which led to the assassination of four caliphs, the Abbasid empire was actually fragmented and relatively independent dynasties emerged by local military powers called "Amir" in various parts of the Islamic lands. These new dynasties, such as the Saffarids, sought autonomy and decentralization, unlike previous rulers such as the Tahirids.[citation needed]
