Jariri (also spelled Jariri) is an Islamic school of jurisprudence that was founded by Muhammad ibn Jarir al-Tabari (838-923). It is one of the four major schools of Sunni Islam, along with the Hanafi, Maliki, and Shafi'i schools. The Jariri school is based on the teachings of al-Tabari and his students, and it emphasizes the importance of hadith (sayings of the Prophet Muhammad) and ijtihad (independent reasoning).
