Why are There Two Sects of Muslim? What is the Difference Between Sunni and Shia?

Two separate branches of Muslim predominate this faith. 90% of the Muslim world is Sunni, and 8% is Shia in faith. The followers of Shia are commonly found in Iran, Iraq, Lebanon, Bahrain, and a few other places. The difference between Sunni and Shia arose because of a political division at the time in history when Shia followers went their separate way. Yet, while the split started as a difference of opinion in politics, some significant theological differences emerged later, with Shia incorporating many unconventional, foreign concepts into their theology. The Sunni and Shia split found its origin in a disagreement about the leadership of the Muslim community after the death of Prophet Muhammad PBUH. After his death, his companions were forced to choose the next leader, the ruler, and the successor of the Muslim community, commonly known as the Caliphate. Sunnis believed that Prophet Muhammad PBUH did not explicitly designate his replacement, and they needed to appoint this leader by mutual consultation. The Shia believed that the Prophet PBUH designated his cousin and son-in-law, Ali PBUH, to assume the role of Caliph.Sunni Muslims deemed Abu Bakr R.A., the Prophet's closest companion, as the fittest to lead the Muslim community. Abu Bakr became the first Caliph, and Ali eventually became the fourth, serving in the wake of Abu Bakr, Umar, and Uthman, peace be upon them. Ali was well-satisfied with the decision to appoint Abu Bakr R.A. as the ruler, but others were less pleased.The word Sunni comes from the term Sunnah, which refers to the teachings and practice of Prophet Muhammad PBUH, who in turn was taught by Angel Gabriel—who, for his part, learned the faith from God. Sunni Muslims consider themselves followers of Islam's orthodox tradition, adhering to the pure, uninfluenced faith taught by Prophet Muhammad PBUH. Shia linguistically means party, sect, supporters, or a group of similar-minded people. Shia is an abbreviation for Shiatu Ali, which signifies a group or supporters of Ali. Shia was a political faction that claimed the cousin and son-in-law of Prophet Muhammad, PBUH, should lead the Islamic community as the Caliphate in place of Abu Bakr R.A.Initially, this group of Ali's supporters, known as Shia, stood against the Umayyads political party but remained purely Sunni in their theology and faith, unlike modern-day Shia. Yet, with passing years, significant doctrine/theological differences arose. The famous 12 Imams that certain Shia holds in the highest regard were Sunni in Creed, not Shia.If Prophet Muhammad PBUH explicitly appointed Ali PBUH, as the Shia claim, that would mean Abu Bakr was appointed unjustly in the role of a caliph. It means he disobeyed and went against the wishes of the Prophet, PBUH, despite his role as his closest associate and dearest friend. Additionally, this move implied that the companions who accepted Abu Bakr R.A. as the Caliphate went against the Prophet PBUH despite earning a high rank and God's praise in the Holy Quran.Many beliefs of Shiism claim no basis in the religion of Islam. Shiism evolved from its role as a political sect supporting and favoring the leadership of Ali and his descendants, who they label as Imams, over more qualified companions, to a holder and conveyor of strange ideas foreign to Islam.Support the show
