Juz'

A juzʼ (Arabic: جُزْءْ; pl.: أَجْزَاءْ, ajzāʼ; lit. 'part') is one of thirty parts of varying lengths into which the Quran is divided. It is also known as parah (Persian: پَارَه) in Iran and subsequently the Indian subcontinent. There are 30 ajzāʼ in the Quran, also known as سِپَارَہ – sipārah (in Persian si means 30) (thirty parts).

Division into ajzāʼ has no relevance to the meaning of the Qurʼān and anyone can start reading from anywhere in the Qurʼān. During medieval times, when it was too costly for most Muslims to purchase a manuscript, copies of the Qurʼān were kept in mosques and made accessible to people; these copies frequently took the form of a series of thirty parts (juzʼ). Some use these divisions to facilitate recitation of the Qurʼān in a month—such as during the Islamic month of Ramadan, when the entire Qurʼān is recited in the Tarawih prayers, typically at the rate of one juzʼ a night.
