The Shia-Sunni divide in Islam originated after Prophet Muhammad’s death in 632 CE over who should lead the Muslim community, shaping theological, political, and cultural differences. Below is a concise explanation of their differences and the distribution of their followers by country.
Key Differences Between Shia and Sunni Islam
- Leadership and Succession:
- Sunni: Believe the leader (caliph) should be chosen by consensus or election from among the Prophet’s companions. They accept Abu Bakr, the first caliph, as Muhammad’s rightful successor.
- Shia: Believe leadership should remain within the Prophet’s family, specifically through Ali, his cousin and son-in-law, and his descendants (Imams). They view Ali as the first Imam and reject the first three caliphs’ legitimacy.
- Theological Beliefs:
- Sunni: Emphasize the Quran and Sunnah (Prophet’s traditions) as interpreted by scholars. They don’t attribute divine qualities to Imams.
- Shia: Recognize Imams as divinely guided, infallible leaders with spiritual authority. Twelver Shia (the majority) believe in 12 Imams, the last of whom (Mahdi) is in occultation and will return.
- Note: Smaller Shia sects, like Ismailis, differ (e.g., recognizing a different line of Imams).
- Religious Practices:
- Both share core practices (prayer, fasting, pilgrimage), but differences exist:
- Shia: Combine certain daily prayers (e.g., noon and afternoon), allow temporary marriage (mut’ah), and emphasize mourning rituals for Imam Hussein (e.g., Ashura).
- Sunni: Follow stricter prayer timings, reject mut’ah, and have less focus on mourning rituals.
- Shia often venerate shrines of Imams, which some Sunnis consider excessive.
- Both share core practices (prayer, fasting, pilgrimage), but differences exist:
- Legal Schools:
- Sunni: Follow four main legal schools (Hanafi, Maliki, Shafi’i, Hanbali) for interpreting Islamic law.
- Shia: Primarily follow the Ja’fari school, which differs in inheritance, marriage, and ritual laws.
- Population:
- Sunni: 85-90% of the world’s 1.9 billion Muslims (1.6 billion).
- Shia: 10-15% (190-285 million), with Twelver Shia being the largest group, followed by Ismailis and Zaydis.
Distribution of Shia and Sunni Followers by Country

The distribution is based on majority populations or significant minorities, drawn from demographic data and regional trends.
Predominantly Sunni Countries
Sunnis form the majority in most Muslim-majority countries. Examples include:
- Middle East and North Africa:
- Saudi Arabia (~90% Sunni, Hanbali/Wahhabi influence)
- Egypt (~90% Sunni, Maliki/Shafi’i)
- Turkey (~80-85% Sunni, Hanafi)
- Jordan (~95% Sunni)
- United Arab Emirates (~80% Sunni)
- Morocco, Algeria, Tunisia (~99% Sunni, Maliki)
- South Asia:
- Pakistan (~80-85% Sunni, Hanafi)
- Bangladesh (~90% Sunni)
- Afghanistan (~80% Sunni, Hanafi)
- Southeast Asia:
- Indonesia (~87% Sunni, Shafi’i)
- Malaysia (~60% Sunni, Shafi’i)
- Sub-Saharan Africa:
- Nigeria (~50% Sunni, Maliki)
- Sudan (~70% Sunni)
- Senegal, Mali, Niger (~95% Sunni, Maliki)
Predominantly Shia Countries
Shia-majority countries are fewer but significant in specific regions:
- Iran: ~90-95% Shia (Twelver), the largest Shia-majority country.
- Iraq: ~60-65% Shia (Twelver), ~30% Sunni.
- Bahrain: ~65-70% Shia (Twelver), though ruled by a Sunni monarchy.
- Azerbaijan: ~65-70% Shia (Twelver), though secular.
Countries with Significant Shia Minorities
- Lebanon: ~30% Shia (Twelver), alongside Sunni and Christian populations.
- Yemen: ~35-40% Zaydi Shia, ~60% Sunni.
- Kuwait: ~20-30% Shia (Twelver).
- Saudi Arabia: ~10-15% Shia (Twelver), concentrated in the Eastern Province.
- Pakistan: ~15-20% Shia (Twelver).
- India: 10-15% of Muslims are Shia (20-30 million, Twelver and Ismaili).
- Syria: ~10-15% Shia (Alawite and Twelver), though Sunnis are the majority.
- Afghanistan: ~15% Shia (mostly Hazara, Twelver).
- Qatar: ~10% Shia.
Mixed or Diverse Regions
- Gulf States: Most have Sunni majorities but host Shia minorities (e.g., Oman has a mix of Sunni, Shia, and Ibadi).
- Central Asia: Countries like Uzbekistan and Turkmenistan are predominantly Sunni, with small Shia communities.
- Diaspora: Shia and Sunni communities coexist in Western countries (e.g., U.S., Canada, U.K.), often with shared mosques.
Additional Notes
- Sectarian Tensions: While Shia and Sunni Muslims coexist peacefully in many areas, political conflicts (e.g., Iran-Saudi rivalry, Iraq’s sectarian violence) have fueled tensions. Historical events, like the 1979 Iranian Revolution (Shia) and the rise of Sunni extremist groups (e.g., ISIS), exacerbate divisions.
- Data Limitations: Exact percentages vary due to lack of recent censuses, political sensitivities, and mixed communities. Estimates are drawn from sources like Pew Research, CIA World Factbook, and regional studies up to 2023.
- Other Sects: Smaller groups like Ahmadiyya, Ibadi (Oman), and Sufi orders exist but are not the focus here.
Fecking religious cultist nutters the lot of them.
It’s the twelver beliefs around the return of the Mahdi that are the issue with the Iranian regime.
