In Islam, qirāʼa refers to the ways or fashions that the Quran, the holy book of Islam, is recited. More technically, the term designates the different linguistic, lexical, phonetic, morphological and syntactical forms permitted with reciting the Quran. Differences between qiraʼat include varying rules regarding the prolongation, intonation, and pronunciation of words, but also differences in stops, vowels, consonants, entire words and even different meanings.. However, the variations don't change the overall message or doctrinal meanings of the Qur'an, as the differences are often subtle and contextually equivalent.Qiraʼat also refers to the branch of Islamic studies that deals with these modes of recitation.
