juz

Juz (plural ajza') is a term used in the study and recitation of the Qur'an to denote one of the thirty parts into which the text is divided. The word literally means "part" or "section" in Arabic. In practice, a juz is a roughly equal division intended to make reading or memorization manageable, though the exact number of verses per juz varies.

The standard Qur'anic text is divided into 30 juz', which facilitates reading the entire Qur'an over a period such as the month of Ramadan, with many readers completing one juz per day. Each juz is further subdivided into two halves called hizbs, making sixty hizbs in total, which helps with pacing and memorization during recitation.

A well-known named juz is Juz’ Amma, the 30th juz. It begins with Surah An-Naba (78:1) and continues to the end of the Qur'an at Surah An-Nas (114:6). Juz’ Amma is especially common for memorization and recitation among learners due to the presence of many relatively short surahs.

Other related divisions used in liturgical practice include the Hizb (half-juz) and the Rub’ al-Hizb (quarter-hizb). While juz divisions aid reading plans and memorization, they are primarily organizational conventions within the Uthmanic koranic text rather than doctrinal categories.
