The Quran is divided into 30 juz’ parts, a structure commonly used to organize recitation during Ramadan.
A juz’ is one of thirty sections of varying length into which the Quran is divided. The divisions are not the same as the Quran’s 114 surahs, because a juz’ can begin or end within a surah. Each juz’ is further divided into two hizb, creating 60 hizb in total.
The thirty-part arrangement is especially practical during Ramadan. Many Muslims aim to complete the Quran during the month by reading approximately one juz’ each day. In congregational night prayers called Tarawih, reciters may likewise organize the readings so that the full Quran is completed across Ramadan.
The divisions are reading aids rather than a claim that the Quran contains only thirty chapters. The 114 surahs are its chapters, while the juz’ system is a separate navigational framework. The final section, Juz’ Amma, is particularly familiar because it contains many short surahs, including those traditionally memorized by beginners.
