Noon Sakinah and Tanween Rules: Izhar, Idgham, Iqlab and Ikhfa with Examples
Ask any Tajweed teacher which rules students meet first, and you will hear the same answer. Noon Sakinah and Tanween. They show up on almost every line of the Quran. Get them right, and your recitation starts to sound the way you hear it from the great reciters. Get them wrong, and even Surah Al-Fatiha can feel a little off.
We teach these four rules every single week, to kids in Texas, reverts in Manchester and busy parents in Johannesburg. Here is how we explain them in class, step by step.
What Is Noon Sakinah, and How Is Tanween Different?
- Noon Sakinah is a noon with no vowel on it: نْ. You find it inside words and at the end of words.
- Tanween is a double vowel at the end of a noun: ـًـ ـٍـ ـٌـ. You write it as a vowel, but you say an extra “n” sound.
So tanween is really a hidden noon sakinah. That is why both follow the exact same four rules. The only thing that decides the rule is the letter that comes right after.
Which Letter Tells You Which Rule to Use?
Look at the next letter. Then use this table.
| Rule | Letters that trigger it | How many | What happens |
|---|---|---|---|
| Izhar | ء ه ع ح غ خ | 6 | Say the noon clearly |
| Idgham | ي ر م ل و ن | 6 | Merge the noon into the next letter |
| Iqlab | ب | 1 | Change the noon to a meem sound |
| Ikhfa | All the other letters | 15 | Hide the noon with a soft nasal sound |
That covers all 28 letters. Learn this one table, and you already know where every rule lives.
When Should You Say the Noon Clearly? Izhar for Beginners
Izhar means “to make clear.” When noon sakinah or tanween meets one of the six throat letters, you say the noon cleanly, with no ghunnah.
| Example | Sounds like | Throat letter |
|---|---|---|
| مَنْ آمَنَ | man aamana | Hamzah ء |
| مِنْهُمْ | min-hum | Ha ه |
| أَنْعَمْتَ | an’amta | Ayn ع |
| عَلِيمٌ حَكِيمٌ | ‘aleemun hakeem | Ha ح |
Why no ghunnah? The throat letters sit far back in the mouth. The noon sits at the tip of the tongue. They are far apart, so there is nothing to blend.
How Does Idgham Merge the Noon into the Next Letter?
Idgham means “to merge.” The noon disappears into the next letter, as if it were never there. Many students remember the six letters with the word يَرْمَلُونَ (yarmaloon).
Which Idgham Letters Have Ghunnah and Which Do Not?
| Type | Letters | Example |
|---|---|---|
| With ghunnah (hum) | ي ن م و | مَنْ يَقُولُ sounds like may-yaqoolu |
| Without ghunnah | ل ر | مِنْ رَبِّهِمْ sounds like mir-rabbihim |
Ghunnah is the soft hum from your nose. In Tajweed, we hold it for 2 counts. Try it: pinch your nose and hum. If the sound stops, you were doing it right.
Why Do Words Like Dunya Break the Idgham Rule?
Here is a detail many websites skip. Idgham only happens between two separate words. Inside one word, you read the noon clearly. There are four such words in the Quran: الدُّنْيَا, بُنْيَانٌ, قِنْوَانٌ and صِنْوَانٌ. Merge the noon in these, and the meaning gets blurry. Scholars call this Izhar Mutlaq.
What Happens When Noon Meets Ba? Iqlab Made Simple
Iqlab means “to turn.” When noon sakinah or tanween comes before ب, the noon turns into a meem sound with a 2-count ghunnah.
- مِنْ بَعْدِ sounds like mim-ba’di
- سَمِيعٌ بَصِيرٌ sounds like samee’um-baseer
Fun fact: your mouth already does this in English. Say “sunbeam” fast. Feel your lips close early? That is almost Iqlab. Just keep the lips lightly together. Do not press them hard.
How Do You Hide the Noon Correctly in Ikhfa?
Ikhfa means “to hide.” This one takes the most practice. The noon is not fully clear, and not fully merged. It sits in between.
- Move your tongue toward the next letter early.
- Do not let the tip of your tongue touch the top of your mouth for a full noon.
- Ghunnah through your nose for 2 counts, then say the next letter.
Examples: أَنتُمْ (antum), مِن قَبْلُ (min qablu), مَن ذَا (man dha). Listen closely and you will notice the ghunnah sounds a bit heavier before letters like ق and lighter before ت. That is the tongue getting ready.
How Can You Spot Each Rule in the Mushaf Before You Recite?
The common Madani Mushaf gives you quiet hints. Once you see them, you cannot unsee them.
| Rule | What the Mushaf shows |
|---|---|
| Izhar | Sukoon on the noon, and tanween marks stacked on top of each other |
| Idgham | No sukoon on the noon, tanween marks offset, and usually a shaddah on the next letter |
| Iqlab | A small meem above or below the noon or tanween |
| Ikhfa | No sukoon on the noon, tanween marks offset, and no shaddah on the next letter |
What Mistakes Do Students Make Most, and How Do We Fix Them?
After years of live classes, we see the same slips again and again.
- Ghunnah during Izhar. The fix: stop the sound right after the noon.
- Saying a full “n” in Ikhfa. English speakers do this a lot. The fix: keep the tongue tip off the roof of your mouth.
- Pressing the lips hard in Iqlab. The fix: think “soft touch,” not “seal.”
- Merging inside one word, like dunya. The fix: remember the four-word exception.
Reading about rules helps. But your ear cannot always catch your own mistakes. That is the honest truth.
Where Can You Practice These Rules with a Live Tajweed Teacher?
In our online Tajweed rules course, a teacher listens to every word you read and corrects you on the spot. Here is what you get:
- Live one-on-one lessons on Zoom, at a time that fits your week.
- Ijazah-certified teachers, male and female, who teach kids, adults and reverts.

Frequently Asked Questions About Noon Sakinah and Tanween
What are the four rules of Noon Sakinah and Tanween?
The four rules are Izhar (say the noon clearly), Idgham (merge it into the next letter), Iqlab (turn it into a meem sound) and Ikhfa (hide it with a soft nasal sound). The letter that comes right after the noon sakinah or tanween decides which rule applies.
What is the difference between Noon Sakinah and Tanween?
Noon sakinah is a noon with no vowel on it, and it can appear inside or at the end of a word. Tanween is a double vowel at the end of a noun, and you pronounce it with an extra “n” sound. Both follow the same four rules.
How many letters trigger each rule?
Izhar has 6 letters, Idgham has 6, Iqlab has 1 (the letter ba), and Ikhfa has the remaining 15. Together they cover all 28 letters of the Arabic alphabet.
How long should I hold ghunnah?
Hold ghunnah for 2 counts. This applies to Idgham with ghunnah, Iqlab and Ikhfa. There is no ghunnah in Izhar, and none in Idgham without ghunnah (the letters lam and ra).
Why is there no Idgham in words like Dunya?
Idgham happens only between two separate words. Four words in the Quran have a noon sakinah followed by an Idgham letter inside the same word: Dunya, Bunyan, Qinwan and Sinwan. You read the noon clearly in them, which is called Izhar Mutlaq.
How do I recognize each rule in the Mushaf?
Look at the marks on the noon or tanween. Izhar shows a sukoon on the noon, or stacked tanween marks. Idgham and Ikhfa show no sukoon, with offset tanween marks, and Idgham usually has a shaddah on the next letter. Iqlab shows a small meem.
How long does it take to learn these rules?
With steady practice, most of our students understand and apply the core rules within 3 to 6 months. Our online Tajweed rules course uses live one-on-one lessons on Zoom, and your teacher corrects you on the spot.
Can I start if I do not know Arabic or I am a beginner?
Yes. No Arabic is needed to start, and we can begin from the alphabet with our Noorani Qaida course. We teach kids, adults and reverts, with male and female teachers.
Can I try a class before I enroll?
Yes. Book a free trial class. Read one short surah for your teacher, and we will show you which of the four rules to work on first.
