How to revise hifz and stop forgetting the Quran
Memorising the Quran is half of hifz; keeping it is the other half. The Prophet ﷺ warned that the Quran escapes from memory faster than a camel from its rope. Here is the revision system hifz teachers use, how much to revise at each stage, and what to do when a juz starts slipping.

The Prophet’s warning
“Keep refreshing your knowledge of the Quran, for by the One in whose hand is my soul, it slips away faster than camels from their tethers” (Sahih al-Bukhari 5033, Sahih Muslim 791). Revision is not optional for a hafiz; it is the work of a lifetime.
The three layers of revision
| Layer | What it covers | How often |
|---|---|---|
| Sabaq | Today’s new lesson | Recited to the teacher until perfect |
| Sabqi (sabaq para) | The last 7–20 pages, or the current juz | Every day, read to the teacher or a partner |
| Manzil (dhor) | Everything memorised before that | A fixed portion every day, so the whole hifz is revised in a regular cycle |
Different madrasas use different names (dhor, manzil, murāja‘ah), but the structure is the same: new, recent and old, every day. The details of the new lesson are in how to memorise the Quran.
How much manzil to revise
A common rule of thumb: the more you have memorised, the more you revise each day, so the whole hifz comes round regularly.
| Memorised so far | Daily manzil | Full cycle |
|---|---|---|
| 1–5 juz | ½ juz | 2–10 days |
| 6–10 juz | 1 juz | 6–10 days |
| 11–20 juz | 2 juz | 6–10 days |
| 21–30 juz | 3 juz | 7–10 days |
| Complete hafiz | 3–5 juz | 6–10 days |
These are guides, not rules; your teacher adjusts them to your strength in each juz. Our hifz planner helps you balance new lines against revision.
Ways to make revision stick
- Revise in salah. Recite your manzil in sunnah and night prayers; it tests memory without the page.
- Use the same mushaf. Visual memory of the page is powerful; changing print layout weakens it. Many UK hifz students use a 13-line or 15-line IndoPak mushaf, or the 15-line Madinah mushaf.
- Recite to someone. A teacher or partner catches the small slips you do not hear yourself.
- Mark weak places. Note mutashābihāt (similar verses) and give them extra repetition.
- Revise at a fluent pace. Revision can be at tadweer or hadr speed; see the speeds of recitation.
- Protect the time. Fix revision to a part of the day, such as after Fajr, and keep it even when busy.
When a juz starts slipping
- Stop adding new sabaq for a week or two.
- Read the weak juz from the mushaf several times, then recite a few pages from memory each day.
- Read it to a teacher before moving it back into your normal manzil.
Most people who memorise as children need a structured return in adulthood. In our online hifz course, a teacher listens to your manzil one-to-one and keeps the cycle going. Read more on what it means to be a hafiz.
Frequently asked questions
Why do I keep forgetting what I memorised?
Usually because new memorisation has outpaced revision. Memory fades without repetition; the fix is a fixed daily manzil, even if it means memorising fewer new lines for a while.
How much should a hafiz revise daily?
Many teachers recommend at least one juz a day for a complete hafiz, and some as much as five, so that the whole Quran is revised within one to four weeks. Revising in salah counts too.
What should I do if I have forgotten a lot?
Pause new memorisation, list your juz from strongest to weakest, and rebuild the weakest a few pages a day, reading them to a teacher. It comes back faster than learning it the first time.
