Hijri yearThe Hijri year (سَنة هِجْريّة) or era (التقويم الهجري at-taqwīm al-hijrī) is the era used in the Islamic lunar calendar. It begins its count from the Islamic New Year in which Muhammad and his followers migrated from Mecca to Yathrib (now Medina) in 622 CE. This event, known as the Hijrah, is commemorated in Islam for its role in the founding of the first Muslim community (ummah). In the West, this era is most commonly denoted as AH (Anno Hegirae ˈænoʊ_ˈhɛdʒᵻriː, 'in the year of the Hijra') in parallel with the Christian/Common (AD/CE) and Jewish eras (AM) and can similarly be placed before or after the date.
Dhimmi(ذمي , ˈðimmiː, collectively أهل الذمة / "the people of the covenant") or (معاهد) is a historical term for non-Muslims living in an Islamic state with legal protection.

Shia Islam holds that Ali ibn Abi Talib was the designated successor to the Islamic prophet Muhammad.

Islamic calendarThe Hijri calendar (ٱلتَّقْوِيم ٱلْهِجْرِيّ), also known in English as the Muslim calendar and Islamic calendar, is a lunar calendar consisting of 12 lunar months in a year of 354 or 355 days. It is used to determine the proper days of Islamic holidays and rituals, such as the annual fasting and the annual season for the great pilgrimage.

Poll taxA poll tax, also known as head tax or capitation, is a tax levied as a fixed sum on every liable individual (typically every adult), without reference to income or resources. Poll is an archaic term for "head" or "top of the head". The sense of "counting heads" is found in phrases like polling place and opinion poll. Head taxes were important sources of revenue for many governments from ancient times until the 19th century. In the United Kingdom, poll taxes were levied by the governments of John of Gaunt in the 14th century, Charles II in the 17th and Margaret Thatcher in the 20th century.

ZaydismZaydism (الزَّيْدِيَّة) is a branch of Shia Islam that emerged in the eighth century following Zayd ibn Ali‘s unsuccessful rebellion against the Umayyad Caliphate. In contrast to other Shia Muslims of Twelver Shi'ism and Isma'ilism, Zaydis, also sometimes incorrectly called Fivers, consider Zayd to be the Imam to whom obedience is obligatory, due to him being a patrilinial descendent of Fatima and making the Call (Dawah) to jihad, two necessary qualities for an Imam of Obedience for the Zaydis.
