Maddhab in the context of "Muslims in Turkey"

Islam is by far the most practiced religion in Turkey. Most Turkish people are Sunni Muslims, and most of them belong to the Hanafi school of jurisprudence. Smaller numbers belonging to the Alevi, Ja'fari and Alawite minorities. The established presence of Islam in the region that now constitutes modern Turkey dates back to the later half of the 11th century, when the Seljuks started expanding into eastern Anatolia.

While official records indicate the population of Turkey to be 99.8% Muslim, most surveys estimate the percentage to be around 85 to 95%. The Hanafi school of fiqh (maddhab) of Sunni Islam makes up about 90% of the Muslim population, with the remaining Muslim sects consisting of Alevis (close to 10%), Ja'faris (representing 1%) and Alawites (with an estimated population of around 500,000 to 1 million, or about 1%). With a sizeable part of population being Cultural Muslims, there is also a minority of Sufi and non-denominational Muslims.

Ja'far ibn Muhammad al-Sadiq (Arabic: جعفر ابن محمد الصادق, romanized: Jaʿfar ibn Muḥammad al-Ṣādiq; c. 702–765) was a Muslim scholar, jurist, hadith transmitter and the sixth and last agreed-upon Shia Imam amongst Twelvers and Isma'ilis. Known by the title al-Sadiq ("The Truthful"), Ja'far was the eponymous founder of the Ja'fari school of Islamic jurisprudence. In the canonical Twelver hadith collections, more traditions are cited from Ja'far than that of the other Imams combined, although their attribution to him is questionable, making it hard to determine his actual teachings. Among the theological contributions ascribed to him are the doctrine of nass (divinely inspired designation of each Imam by the previous Imam) and isma (the infallibility of the Imams), as well as that of taqiya (religious dissimulation under persecution).

Al-Sadiq is also revered by Sunni Muslims as a reliable transmitter of hadith, and a teacher to the Sunni scholars Abu Hanifa and Malik ibn Anas, the namesakes of the Hanafi and Maliki schools of jurisprudence. Al-Sadiq also figures prominently in the initiatic chains of many Sufi orders. A wide range of religious and scientific works were attributed to him, though no works penned by al-Sadiq remain extant.

Islam is the largest religion in Indonesia, with 87.06% of the Indonesian population identifying themselves as Muslims, based on civil registry data in 2023. In terms of denomination, the overwhelming majority are Sunni and non-denominational Muslims; the Pew Research Center estimates them as comprising ~99% of the country's Muslim population in 2011, with the remaining 1% being Shia, who are concentrated around Jakarta, and about 400,000 Ahmadi as well.

In terms of schools of jurisprudence, based on demographic statistics, 99% of Indonesian Muslims mainly follow the Shafi'i school, although when asked, 56% do not adhere to any specific school. Trends of thought within Islam in Indonesia can be broadly categorized into two orientations: "modernism", which closely adheres to orthodox theology while embracing modern learning, and "traditionalism", which tends to follow the interpretations of local religious leaders and religious teachers at Islamic boarding schools (pesantren). There is also a historically important presence of a syncretic form of Islam known as kebatinan.

Malik ibn Anas (Arabic: مَالِك بْن أَنَس, romanized: Mālik ibn ʾAnas; c. 711–795), also known as Imam Malik, was a Muslim scholar, jurist, muhaddith and traditionalist who is the eponym of the Maliki school, one of the four schools of Islamic jurisprudence in Sunni Islam.

Born in Medina into the clan of Humayr which belonged to the Banu Taym of Quraysh, Malik studied under Hisham ibn Urwa, Ibn Shihab al-Zuhri, Ja'far al-Sadiq, Nafi ibn Sarjis and others. He rose to become the premier scholar of hadith in his day, Referred to as the Imam of Medina by his contemporaries, his views in matters of jurisprudence became highly cherished both in his own life and afterward, becoming the eponym of the Maliki school, one of the four major schools of Islamic jurisprudence. His school became the normative rite for Sunni practice in much of North Africa, al-Andalus (until the expulsion of medieval native Iberian Muslims), a vast portion of Egypt, some parts of Syria, Yemen, Sudan, Iraq, and Khorasan, and the prominent orders in Sufism, the Shadili and Tijani.

Muhammad ibn Abd al-Wahhab ibn Sulayman al-Tamimi Al Najdi (1703–1792) was an Arab Muslim scholar, theologian, preacher, activist, religious leader, jurist, and reformer, who was from Najd in Arabian Peninsula and is considered as the eponymous founder of the Wahhabi movement.

The label "Wahhabi" is not claimed by his followers but rather employed by Western scholars as well as his critics. Born to a family of jurists, Ibn Abd al-Wahhab's early education consisted of learning a fairly standard curriculum of jurisprudence according to the Hanbali school, which was most prevalent in his area of birth. He promoted strict adherence to traditional Islamic law, proclaiming the necessity of returning directly to the Quran and Hadith literature rather than relying on medieval interpretations, and insisted that every Muslim – male and female – personally read and study the Quran. He opposed taqlid (blind following) and called for the use of ijtihad (independent legal reasoning through research of scripture).
