Allah gives us his word to keep the Quran away from any corruption or alteration. He said this many times in the Quran. You can also see this in reality through the cautious observation of Hofaz, as Allah provides many means so that people can learn, memorize, and review. 

Among the means He has ordained for this purpose is its division into Ajzaa, a plural of ‘Juz’, Ahzab, and smaller portions. So, let’s learn what juz means in the Quran, and how to recognize it with examples.

What does Juz mean in the Quran?

Juz (جزء) is a conventional divider of the Quranic text. The word juz means part, and it divides the Quran into 30 almost equal parts. Or a bit more (22 or 23). 

Every Juz is about 20 pages long, sometimes a little more, around 22 or 23 pages on the script and print.

How to Identify Juz in the Quran?

When you recite the Quran in any Mushaf, you will find the following sign at the beginning of several verses: 

(۞)

Due to the widespread division of the Quran into Juzʾ’, this symbol marks the Rubʿ al-Ḥizb, which divides each Juzʾ into eight equal parts — each representing one-eighth (¼ of a Ḥizb or 1/8 of a Juzʾ).

Benefits of Dividing the Quran into 30 Juz:

Although, as mentioned, these divisions are based on the number of letters and have no relation to thematic unity or the completion of chapters. The popularity of this division arose for several reasons. 

1. Helps You Divide Your Reading and Plan to Finish Within a Month

Muslims typically ensure that they recite the entire Quran during Ramadan. This becomes much easier when you know that the Quran is divided into 30 Juzʾ. By reading one Juzʾ every day, you can complete the Quran within a month.

You can easily make up for any missed days without complicated planning. You can easily make a Quran reading schedule and planner for all months

2. Makes It Easier to Find and Refer to Specific Sections

When you know which Juzʾ a certain Ayah is located in, it becomes much simpler to refer to it or share it with others. You can easily tell anyone carrying a Mushaf about the Juzʾ number of the verse.
The Mushaf’s clear signs marking each Juzʾ allow readers to quickly find any section or verse. For example, this organization helps both learners and readers move through the Quran with ease in our Online Quran Recitation Course.

3. Simplifies Memorization and Review

Knowing the Juzʾ divisions helps you organize your memorization plan. You can aim to memorize one Juzʾ per week and review another at the same time. This approach supports steady progress and balanced repetition—essential for strong memorization.
In our Quran memorization and Hifz course, we follow this structure to help students memorize Juzʾ after another, ensuring both understanding and retention.

4. Encourages Consistency in Regular Recitation and Reflection

The ultimate goal of reciting the Quran is to understand and apply it in daily life. Using the Juzʾ divisions as a recitation guide makes it easier to stay consistent.

You can pair your reading with Tafsir study, allowing for deeper reflection and a more meaningful connection with the Quran. You can revise the lessons of our Online Quran Tafseer Course easily.

5. Helps You Remember Where You Last Stopped

Remembering the Juzʾ number where you last stopped is much easier than recalling the exact verse or page. This makes it simple to continue your recitation or memorization without losing track..

6. Motivates You to Complete the Quran

Imagine you are on a long journey, and you know every stop along the way; that’s exactly what the Juzʾ divisions offer. When you can see your progress clearly through each Juzʾ, you feel encouraged to continue in the fastest way to memorize the Quran.

Making the idea of completing the entire Quran much less overwhelming. Each finished Juz gives you a sense of accomplishment to keep going.

The Origin of the Quran’s Division into Juz:

The early Othmānic Mushaf was devoid of the divisions we know today, just as they were free of diacritical marks and vowel signs. Although our prophet`s companions used other systems of division based on different considerations.

There is no certainty about who first established today`s Juz divisions. However, some scholars report that Al-Ḥajjāj ibn Yūsuf al-Thaqafī introduced it and that the divisions were based on the number of letters.

Today, these divisions are widely accepted, providing a cohesive structure for the Quran that is acknowledged and followed across all Muslim communities.
