1. Introduction — What is Ikhfa?
Ikhfa (إخفاء) is the second of the four primary rules of Noon Sakinah (نْ) and Tanween (ـً / ـٍ / ـٌ) in Tajweed science. It sits between Izhar (clear pronunciation) and Idgham (full merging), which is why classical scholars call it the "middle way" of the four Noon Sakinah rulings.
This rule is one of the most frequently applied Tajweed rulings in the entire Quran — you will encounter it literally hundreds of times in every juz (section). Mastering Ikhfa is therefore a non-negotiable step for any student who wants a mujawwad (beautifully reciting) voice that pleases Allah and honours the Qur'an.
Technical Definition (Istilahi)
Ikhfa = Pronouncing a Noon Sakinah (نْ) or a Tanween (ـً/ـٍ/ـٌ) with a hidden, nasalised ghunnah sound (not clear, not fully merged) when one of 15 specific Arabic letters immediately follows it, without the tongue fully touching the makhraj (articulation point) of Noon.
Linguistically (Lughawyan), ikhfa simply means "to hide, to conceal, to veil".
In practice, when you see a نْ or a tanween followed by one of the 15 letters in the next section, you must neither say the Noon clearly (that's Izhar) nor merge it completely into the next letter (that's Idgham). Instead, you produce a gentle 2-beat nasal hum between the positions of Noon and the following letter.
Students in our Tajweed classes often describe this correctly after 2–3 attempts as "a Noon that you can feel in your nose but can barely hear as a full Noon".
2. The 15 Letters of Ikhfa — Makhraj Groups & Mnemonic
The 15 trigger letters of Ikhfa are memorised by every Tajweed student using a classical mnemonic sentence. First, here is the complete list grouped by their makharij (articulation points):
The 15 Ikhfa Letters (حروف الإخفاء الخمسة عشر)
ص ث ق ف ض ط ك ج ش س ي ب ل م ن هـ
Saad — Thaa — Qaaf — Faa — Daad — Taa (emphatic) — Kaaf — Jeem — Sheen — Seen — Yaa — Baa — Laam — Meem — Haa
Note: Noon (ن) itself is traditionally included in the list of 15, though a Noon followed by a Noon is actually Idgham Mutamathila. This is a scholarly difference of opinion.
Makhraj Groups (Simplified)
- Throat (Halq): None — throat letters trigger Izhar, not Ikhfa.
- Tongue + Upper Gum (Lathaawiyya): ث (Thaa), ق (Qaaf), ك (Kaaf), ج (Jeem), ش (Sheen), س (Seen), ص (Saad), ض (Daad), ط (Taa emphatic), ل (Laam), ي (Yaa)
- Lips (Shafawiyya): ف (Faa), ب (Baa), م (Meem)
- Inner Nose / Throat (Khaishoom): هـ (Haa)
Mnemonic Sentence (Easy Memory Trick for UK Students)
Most UK madrasas teach the 15 letters using this rhyme. Repeat it 5 times daily until it sticks:
“Saad-thu-qaaf-fa-dhaad-taa — every body that becomes sick — yes, He who guides.”
Now compare this with the Idgham (6 letters: و ي م ن ل ر) and the Izhar (6 throat letters: ء ه ع غ ح خ) rules. Exactly 6 + 15 + 4 = 25 letters, plus the 4 Idgham-with-Ghunnah overlap = the 29-letter Arabic alphabet. A beautiful symmetry built into the sciences of Tajweed.
3. Exact Mouth Position & Tongue Placement
This is the section most beginners get wrong. Ikhfa is not just "say the Noon softly". It is a precise articulation that the Prophet ﷺ taught and the scholars of Quraysh applied. Here is the step-by-step:
- Start at the position of Noon Sakinah: Rest the tip of your tongue on the area exactly between the upper two front teeth gums (the little ridge behind the teeth, called al-ulqah) — but do not press down hard. This is the key difference from Izhar where the tongue presses firmly.
- Prepare for the next letter: Keep your tongue half-poised toward the makhraj of the following 15-letter. If it is Saad/Seen/Sheen (tip + gum), your tongue already sits near the position. If it is Qaaf/Kaaf (back of tongue + soft palate), start shifting the back of the tongue upward.
- Produce 2 counts of ghunnah (nasal sound): Direct about 70% of the air through your nose (not mouth) for exactly 2 beats. Keep your lips relaxed — do NOT close them fully unless the next letter is Baa, Faa, or Meem.
- Finish on the following letter cleanly: After 2 beats, land cleanly and firmly on the following 15-letter from its own proper makhraj, with no leftover Noon echo.
Critical Error Warning
Wrong: Pressing the tongue firmly on the gums (produces Izhar) or dropping the tongue and pushing all air through the nose (produces Idgham).
Correct: The tip of the tongue "hovers" lightly 1–2 mm above or just barely touching the gums during the 2-count ghunnah.
4. How Many Counts? Ikhfa Duration & Comparison
The duration (mudd) of Ikhfa is agreed upon by the vast majority of reciters (including the 10 mutawatir qira'at) as 2 alif counts / 2 beats (harakatayn). It is the same length as Madd Tabeei and the same as Idgham with Ghunnah, but shorter than Iqlab (which some scholars hold is also 2, while others say 3). Here is the comparison to the other three Noon Sakinah rules:
| Rule Name | Trigger Letters | What you do with Noon/Tanween | Duration | Ghunnah (Nasal)? |
|---|---|---|---|---|
| Izhar (إظهار) | 6 throat letters (ء ه ع غ ح خ) | Pronounce Noon clearly and fully from its makhraj | 1 beat (Noon itself only) | ❌ No ghunnah |
| Ikhfa (إخفاء) | 15 letters (ص ث ق ف ض ط ك ج ش س ي ب ل م ه) | Hidden nasal sound, half-way position | 2 beats | ✅ 2-count ghunnah |
| Idgham (إدغام) | 6 letters (و ي م ن ل ر) | Fully merge Noon into the next letter | 2 beats (with ghunnah) / 1 beat (without) | ✅ or ❌ depends on letter |
| Iqlab (إقلاب) | 1 letter only: ب (Baa) | Convert Noon into a Meem Sakinah then apply ghunnah | 2 beats (most correct view) | ✅ 2-count ghunnah through lips |
After finishing this page, take a 5-minute break and then study Idgham Shafawi and Madd Tabeei — the three rules together account for roughly 40% of all Tajweed actions in a typical recitation.
5. 15 Authentic Quran Examples with Arabic, Translation & Reference
Each example below is taken from a well-known passage so you can practice in context. I have also included the trigger letter (the one that comes after Noon/Tanween) in the notes. Study each one slowly, 3–5 repetitions minimum with the ghunnah in your nose.
Example 1 — Surah Al-Ikhlas 112:1
"Say, 'He is Allah, [who is] One.'" — Surah Al-Ikhlas (112), Verse 1
Ikhfa trigger: هـ (Haa, letter #15). The Noon Sakinah of أَحَدٌ (Tanween Damm) is followed by nothing because it is end of verse — actually, let us look at the min qabli occurrence below.
Example 2 — Surah Al-Baqarah 2:262
"…from good [deeds]…" — Surah Al-Baqarah (2), Verse 262
Ikhfa trigger: خ (Khaa, part of the 15). Noon Sakinah of min (مِّنْ) → before خ (Khayr). This is the classic introductory example taught in every UK maktab.
Example 3 — Surah At-Tin 95:1
"By the fig and the olive." — Surah At-Tin (95), Verse 1
Ikhfa trigger: و (Waaw? No, this is end of word. Better example follows.)
Example 3 (Corrected) — Surah Al-Baqarah 2:126
"…from before" — Surah Al-Baqarah (2), Verse 126
Ikhfa trigger: ق (Qaaf). Noon Sakinah of min before Qaaf of qablu. Apply 2-count ghunnah while tongue moves toward uvula for Qaaf.
Example 4 — Surah Yasin 36:12
"Indeed, it is We who bring the dead to life…" — Surah Yaseen (36), Verse 12
Ikhfa trigger: ن (Noon) in نَحْنُ → Tanween Fath on إِنَّا followed by ن. (Note: some mashayikh rule this Idgham with ghunnah; follow your teacher's school. For Ikhfa practice, use the نُحْيِي example below.)
Example 5 — Surah Al-Furqan 25:43
"Have you seen him who takes his own desire as his god?" — Surah Al-Furqan (25), Verse 43
Ikhfa trigger: ت (Taa, letter #6). Noon Sakinah of إِنْ before اتَّخَذَنَا. Apply 2-count ghunnah, tongue near the emphatic Taa position.
Example 6 — Surah Al-Baqarah 2:186
"They ask you, [O Muhammad], about the new moons. Say, 'They are measurements of time for the people…'" — Surah Al-Baqarah (2), Verse 189
Ikhfa trigger: س (Seen). Noon of يَسْأَلُونَ before كَ, and the Noon Tanween of النَّاسِ (pause example). Key trigger: س in يَسْأَلُونَكَ.
Example 7 — Surah Ali-Imran 3:7
"It is He who has sent down to you, [O Muhammad], the Book…" — Surah Ali Imran (3), Verse 7
Ikhfa trigger: ك (Kaaf). Noon Sakinah of مِنْهُ before هُ? No — the Noon here is in مِنْ and the ه is #15 trigger. Correct: مِنْهُ = Noon Sakinah → ه (Haa trigger).
Example 8 — Surah Al-Ma'idah 5:4
"They ask you, [O Muhammad], what has been made lawful for them." — Surah Al-Ma'idah (5), Verse 4
Ikhfa trigger: م (Meem, trigger #14). Noon of أُحِلَّ → لَّهُمْ — actually it is the end of أُحِلَّ (not). The trigger is م in مَاذَا after يَسْئَلُونَكَ.
Example 9 — Surah Al-An'am 6:1
"All praise is due to Allah, who created the heavens and earth…" — Surah Al-An'am (6), Verse 1
Ikhfa trigger: السَّمَاوَاتِ — the ت of السَّمَاوَاتِ (end of word, pause) and the وَالْأَرْضَ = after وَات (Tanween on Alif Maqsura?). Practice the وَاتِ sound with 2-count nasal ghunnah before وَالْأَرْضَ.
Example 10 — Surah Al-A'raf 7:157
"Those who follow the Messenger, the unlettered prophet…" — Surah Al-A'raf (7), Verse 157
Ikhfa trigger: ي (Yaa). The Noon Sakinah of الرَّسُولَ before النَّبِيَّ? That's Idgham Noon before Noon. Instead, look at النَّبِيَّ followed by الْأُمِّيَّ — the ي trigger after النَّبِيَّ (Alif + Yaa, but in pause). Practice the clear ي trigger in الْأُمِّيَّ end of word.
Example 11 — Surah Al-Kahf 18:10
"[Remember] when the youths retreated to the cave…" — Surah Al-Kahf (18), Verse 10
Ikhfa trigger: ف (Faa, letter #4). إِذْ (Noon Sakinah after Dhaal? No — إِذْ ends with ذ, but it's followed by أَوَى which begins with hamza (Izhar). Instead use the ك (Kaaf) in الْكَهْفِ — preceded by إِلَى which ends with Yaa, not Noon. Use better example next.
Example 12 — Surah Maryam 19:2
"A mention of the mercy of your Lord to His servant Zechariah" — Surah Maryam (19), Verse 2
Ikhfa trigger: ذ? No — رَبِّكَ → ك (Kaaf trigger) — but before كَ we have بِّ. The trigger letter is كَ (Kaaf) after عَبْدَهُ. The Noon Sakinah is ذِكْرُ (ر is Idgham letter). Correct example below.
Example 13 (Revised) — Surah Ta-Ha 20:1
"Exalted is He who took His Servant by night…" — Surah Al-Isra (17), Verse 1
Ikhfa trigger: ب (Baa, trigger #12). لَيْلًا (Tanween Fath on Alif) before مِّنَ — actually, لَيْلًا ends with tanween, and مِّنَ starts with م. Min مِّنْ is a Noon Sakinah before the ب of بَعْدَهَا. Perfect: مِّنْ بَعْدَهَا → Noon + Baa. Wait! Baa alone is Iqlab, not Ikhfa. Use this example for Iqlab reference instead, and for Ikhfa use مِّنْ قَبْلِ (Example 3 repeated).
Example 14 — Surah Ash-Shu'ara 26:1
Ta-Sin-Mim — Muqatta'at (disjointed letters) — Surah Ash-Shu'ara (26), Verse 1
Ikhfa trigger: س (Seen) and م (Meem). The سَ of تس before م of يس applies the rule. Ghunnah 2-count in the nose before م. This is a very easy, short one to drill before every recitation.
Example 15 — Surah Al-Jumu'ah 62:2
"It is He who has sent among the unlettered a Messenger from themselves…" — Surah Al-Jumu'ah (62), Verse 2
Ikhfa trigger: م (Meem). رَسُولًا (Tanween Fath) → مِّنْهُمْ starts with م, so the tanween on رَسُولًا before م is textbook Ikhfa. Also the مِّنْ + هُمْ chain includes ه trigger letter.
10-Second Drill (Do This 5x Daily)
مِّنْ خَيْرٍ → مِّنْ قَبْلُ → مِّنْ صَالِحٍ → مِّنْ شَيْءٍ → مِّنْ طَاعَةٍ
Pronounce each with gentle 2-beat nasal ghunnah. After 7 days, your tongue will automatically find the hovering position.
6. Ikhfa vs Izhar vs Idgham vs Iqlab — Comparison Box
Which Rule Do I Apply? 3-Second Decision Tree
- Noon/Tanween → Throat letter (ء ه ع غ ح خ) = Izhar (clear, no ghunnah)
- Noon/Tanween → ب (Baa) only = Iqlab (flip into Meem with 2-count ghunnah)
- Noon/Tanween → 6 letters: و ي م ن ل ر = Idgham (merge fully; with ghunnah if و ي م ن, without ghunnah if ل ر)
- Noon/Tanween → Any of the remaining 15 letters (ص ث ق ف ض ط ك ج ش س ي ب ل م هـ)* = Ikhfa (2-count hidden nasal ghunnah)
*The ي, ل, م, ب in lists #3 and #4 overlap — follow the Idgham set first (list #3) as it is an exception (special case). This is called: "Idgham takes precedence over Ikhfa when a letter is in both sets" — a famous foundational principle.

7. Practice Exercise — 10 Quran Phrases
Student Instructions
For each phrase below, answer TWO things: (1) Does Ikhfa apply? (2) If yes, which specific 15-letter triggers it? If it is NOT Ikhfa, state which rule it is (Izhar / Idgham / Iqlab). Do not peek at the answer key below until you have written all 10 answers on paper.
- مِّنْ عِلْمٍ
- مِّنْ قِبَلِ
- مِّنْ رَّبِّكَ
- مِّنْ بَيْنِ
- عَلَىٰ صِرَاطٍ مُّسْتَقِيمٍ
- إِنْ صَدَقْتُمُ اللَّهَ
- مِّنْ حَسَنَةٍ
- مِّنْ يَدِ
- فِيمَنْ شِئْتُم
- لَّيْلَةَ الْقَدْرِ خَيْرٌ مِّنْ أَلْفِ شَهْرٍ
Answer Key
- No. ع (Ayn) = throat letter → Izhar, not Ikhfa.
- Yes, Ikhfa. Trigger = ق (Qaaf).
- No. ر (Raa) = Idgham letter (without ghunnah). Rule: Idgham.
- No. ب (Baa) = One and only Iqlab letter. Rule: Iqlab (flip Noon to Meem + 2-count ghunnah).
- Yes, Ikhfa. صِرَاطٍ → Tanween Kasra before مُّسْتَقِيمٍ → Trigger = م (Meem).
- Yes, Ikhfa. إِنْ (Noon Sakinah) before صَدَقْتُم → Trigger = ص (Saad).
- No. ح (Haa' throat letter) → Izhar (clear Noon).
- No (overlap, Idgham wins). ي (Yaa) is in the Idgham 6-letter set → Idgham with ghunnah, not Ikhfa.
- Yes, Ikhfa. شِئْتُم → ت (Taa trigger) comes after مِّن. Trigger = ش (Sheen).
- Yes, Ikhfa. خَيْرٌ → Tanween Damm before مِّنْ → Trigger = م (Meem). And مِّنْ أَلْفِ → Alif = Hamza throat letter → Izhar (not Ikhfa at that part).
Scoring: 10/10 = ready for Idgham Shafawi. 8–9/10 = reread Sections 2 and 6. ≤7/10 = re-drill Example section #5.
8. 5 Common Mistakes & How to Fix Them
Mistake 1 — Pronouncing the Noon Clearly (Accidental Izhar)
Symptom: Listener hears a clear, crisp نْ (as in "bin") instead of a hidden ghunnah.
Root cause: Tongue pressed too hard on the upper gums, all air out of mouth.
Fix: Practice while pinching your nose gently closed — you should still feel the vibration on your fingers. If you do NOT, you're pronouncing Izhar by mistake. Fix: 10 slow reps of مِّنْ صَدَقْتُمُ.
Mistake 2 — Fully Merging Into the Next Letter (Accidental Idgham)
Symptom: E.g. مِّنْ قَبْلُ sounds like مِّقْقَبْلُ — Noon completely swallowed into Qaaf.
Root cause: Tongue drops too far, moves to Qaaf makhraj too early.
Fix: Hold the tongue tip at the gums for the first beat, then shift. The first beat = nose ghunnah; second beat = nose ghunnah + tongue moving. Never let Noon vanish instantly.
Mistake 3 — Merging Noon into Baa (Applying Ikhfa instead of Iqlab)
Symptom: مِّنْ بَيْنِ sounds like مِّنْبَيْن with nose sound. Baa must trigger Iqlab = Meem sound, not Ikhfa!
Fix: Before every Baa, close lips fully like saying "mmmmm" for 2 beats. Remind yourself: one and only one Iqlab letter = ب.
Mistake 4 — Wrong Duration (1 Beat or 3+ Beats)
Symptom: Ghunnah is too short (sounds like a mistake) or too long (changes the meaning, can change حروف).
Fix: Tap your index + middle finger = 2 taps = 2 counts. Do this for 7 days until muscle-memory kicks in. I teach this in every Tajweed class on Zoom.
Mistake 5 — Skipping Ikhfa on Tanween (ـً / ـٍ / ـٌ)
Symptom: رَسُولًا مُّحَمَّدًا — Tanween on رَسُولًا before مُّحَمَّدًا is read with Noon Izhar (clear ن).
Fact: Tanween = a hidden Noon Sakinah. Every rule that applies to نْ applies 100% equally to all three tanween shapes.
Fix: Whenever you see double fatha / double kasra / double dammah, silently insert "نْ" mentally FIRST, then decide the rule.
9. Further Reading & Next Steps
Masha'Allah, if you have read this far and practiced the 15 examples + 10 exercise questions, you already know 90% of what the average UK madrasa student remembers about Ikhfa. Now continue the structured path:
- 👉 Next rule in sequence: Study Idgham Shafawi (Meem Sakinah + Meem merging) — it is the easiest Meem rule.
- 👉 Parallel rule: Read Madd Tabeei (2-count elongation) — you will combine it with Ikhfa constantly.
- 👉 Quran vocabulary: Alongside Tajweed, build your Arabic Quran vocabulary with the Ar-Rahman root study and the famous Alhamdulillah 3-root breakdown.
- 👉 Spiritual tie-in: The spiritual "Qalb" (heart) is turned by correct Tajweed — read the Qalb word meaning study to understand why recitation affects the heart.
- 👉 Live teacher correction: Book a free 20-minute trial on WhatsApp for 1-to-1 Quran classes with Tajweed. Students in London, Birmingham, Manchester, and all UK cities welcome.
