what is juz in quran

A juz is one of thirty parts of varying lengths into which the Quran is divided. It is also known as para in Iran and subsequently the Indian subcontinent. There are 30 juzʼs in the Quran, also known as سِپَارَہ – sipāra (thirty parts). Division into ajzāʼ has no relevance to the meaning of the Qurʼān and anyone can start reading from any part. Each juz is further divided into ḥizbayni (lit. "two groups", singular: ḥizb), and each hizb subdivided into four quarters, making eight quarters per juzʼ, called maqraʼ (lit. "reading"). There are 240 of these quarters (maqraʼs) in the Qurʼān. These maqraʼ are often used as practical sections for revision when memorizing the Qurʼān. The most commonly memorized juzʼ is juzʼ ‘amma, the 30th juzʼ, containing chapters (sūrah) 78 through 114, with most of the shortest chapters of the Qurʼān. Juzʼ ‘amma is named, like most ajzāʼ, after the 1st word of its 1st verse (in this case chapter 78).
