In Quran memorization (Hifz), sabaq is the day’s newly memorized portion, sabqi is the revision of recent lessons (the last few days), and manzil is the scheduled revision of older memorized portions — together they form the daily cycle that keeps memorization from eroding. Advanced students add daur, the complete-Quran revision cycle. A student who does only sabaq every day is building on sand: without sabqi the new lesson fades within days, and without manzil the earlier Juz silently wash away over months.
The three pillars, one by one
1. Sabaq — the new lesson
The portion memorized today, defined by Juz and Surah with verse ranges (e.g., Juz 21, Surah Al-Baqarah 142–152). The teacher listens, corrects, and the record becomes the student’s daily commitment.
2. Sabqi — recent revision
Re-listening to the last few days’ lessons so today’s memorization consolidates. Usually reviewed daily, one-to-one. It is the bridge between “memorized this morning” and “actually retained”.
3. Manzil — older revision
The oldest and most neglected pillar: revising previously memorized Juz on a rolling schedule so nothing is lost. Weak manzil tracking is why a student can “know the whole Quran” in year one and struggle with early Juz in year three.
(+) Daur — the full cycle
For advanced students: revising the entire Quran on a rotating schedule — the maintenance habit of a Hafiz.
Why each needs its own record
Paper registers blur the three into one daily note. Structured records — separately, per Juz/Surah — are what make intervention possible: “this student’s Juz 15 hasn’t been revised in 9 days” is only visible when manzil has its own field. That is the core of digital Hifz tracking: in iilmaa, each pillar is recorded separately with Tajweed scoring 1–5, and the system flags students whose manzil cycle is slipping. (Bengali-language term explanations are in the glossary.)
The daily cycle in practice
| Time | What | Record |
|---|---|---|
| Morning class | Sabaq (new lesson) | Juz/Surah + verse range |
| Same sitting | Sabqi (recent revision) | Last 2–3 days’ lessons |
| Rotating slot | Manzil (older revision) | The Juz due today |
| Advanced only | Daur | Full-Quran cycle position |
The three pillars FAQ
How many verses make a sabaq? Depends on the student’s level and the institution’s standard — common ranges are half a page to a full page. The amount is an institutional decision; the record structure is the same.
What is the difference between manzil and daur? Manzil revises older portions by a per-Juz schedule; daur is the complete-Quran rotating revision of advanced students.
Can software really help with memorization tracking? It removes the matching work: per-Juz records, weak-manzil flags, guardian visibility, and an Ijazah-ready multi-year record. See what Hifz tracking software does — or try it on a 14-day free trial.
