Juz'

A juzʼ (Arabic: جُزْءْ; pl.: أَجْزَاءْ, ajzāʼ;^[1] lit. 'part') is one of thirty parts of varying lengths into which the Quran is divided.^[2][3] 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 ("thirty parts"; in Persian si means 30).

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).^[4] Some use these divisions to facilitate recitation of the Qurʼān in a month—such as during the Islamic month of Ramadan,^[2][3] when the entire Qurʼān is recited in the Tarawih prayers, typically at the rate of one juzʼ a night.^{[citation needed]}
