Abu Hanifa in the context of "Charikar"

The Hanafi school or Hanafism is the largest school of Islamic jurisprudence out of the four principal schools within Sunni Islam. It developed from the teachings of the jurist and theologian Abu Hanifa (c. 699–767 CE), who systemised the use of reasoning (ra'y). Hanafi legal theory primarily derives law from the Quran, the sayings and practices of Muhammad (sunnah), scholarly consensus (ijma) and analogical reasoning (qiyas), but also considers juristic discretion (istihsan) and local customs (urf). It is distinctive in its greater usage of qiyas than other schools.

The school spread throughout the Muslim world under the patronage of various Islamic empires, including the Abbasids and Seljuks. The region of Transoxiana emerged as a centre of classical Hanafi scholarship between the 10th and 12th centuries, which gave rise to the Maturidi school of theology. The Ottoman Empire adopted Hanafism as its official school of law and influenced the legal thought of the school, eventually codifying it as the Mecelle in the 1870s.

Maturidism (Arabic: المَاتُريدِيَّةُ, romanized: al-Māturīdiyya) is a school of theology in Sunni Islam named after Abu Mansur al-Maturidi. It is one of the three creeds of Sunni Islam alongside Ash'arism and Atharism, and prevails in the Hanafi school of jurisprudence.

Al-Maturidi codified and systematized the theological Islamic beliefs already present among the Ḥanafite Muslim theologians of Balkh and Transoxiana under one school of systematic theology (kalām); Abu Hanifa emphasized the use of rationality and theological rationalism regarding the interpretation of the sacred scriptures of Islam.

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.

Zayd ibn ʿAlī (Arabic: زيد بن علي; 695–740), also spelled Zaid, was the son of Ali ibn al-Husayn Zayn al-Abidin, and great-grandson of Ali ibn Abi Talib. He led an unsuccessful revolt against the Umayyad Caliphate, in which he died. The event gave rise to the Zaydiyya sect of Shia Islam, which holds him as the next Imam after his father Ali ibn al-Husayn Zayn al-Abidin. Zayd ibn Ali is also seen as a major religious figure by many Sunnis and was supported by the prominent Sunni jurist, Abu Hanifa, who issued a fatwa in support of Zayd against the Umayyads.

To Twelver and Isma'ili Shias however, his elder half-brother Muhammad al-Baqir is seen as the next Imam of the Shias. Nevertheless, he is considered an important revolutionary figure by Shias and a martyr (shaheed) by all schools of Islam, including Sunnis and Shias.The call for revenge for his death, and for the brutal display of his body, contributed to the Abbasid Revolution.
