In Islam, Qira'at (literally "recitations" or "readings") refers to variants in the recitation of the Quran. There are ten different recognised schools of qira'at, each one deriving its name from a noted Quran reciter or "reader" (Qari). Each reciter recited to two narrators whose narrations are known as riwaya (transmissions) and named after its primary narrator. Each Rawi (singular of riwaya) has turuq (transmission lines) with more variants created by notable students of the master who recited them and named after the student of the master. Passed down from Turuq are wujuh: the wajh of so-and-so from the tariq of so-and-so. There are about twenty riwayat and eighty turuq.
