Noon Saakin rules are the four Tajweed rules — Izhar, Iqlaab, Idghaam, and Ikhfaa — that govern how a Noon carrying a Sukoon (ن) or a Tanween sound is pronounced correctly when reciting the Quran.
Before we shed light on what Noon Saakin rules and tanween are, their definitions, and the difference between Noon Saakin and tanween, we need to make clear why to know these terms and apply them while reciting the Holy Quran.
As we know, reading the Quran well means reciting it correctly and in accordance with the tajweed rules. It was narrated from Aisha that the Messenger of Allah (PBUH) said: “The one who is proficient with the Qur’an will be with the noble and righteous scribes (the angels), and the one who reads it and stumbles over it, finding it difficult, will have two rewards.” Ibn Majah
Ibn Al-Jazari also said in his famous poem about the rules of Tajweed (what means): “The practical application of Tajweed is without doubt compulsory. Who does not read the Quran correctly is a sinner. The Quran was sent down to the Messenger of Allah in this form (with tajweed), which will not change for centuries. And after that, it was passed on to the next generations through reliable chains to our present-day Sheikhs and those with Ijazah. And it (tajweed) is also beautification of recitation and adornment of pronunciation and reading.”
Hence, putting how to learn Tajweed, including Noon Saakin rules, a priority and giving it its due effort and time is of great importance. Also, understanding our responsibilities so that we can receive His mercy is one of our greatest duties.

Table of Contents
What is Noon Sakinah?
Noon Saakin means a Noon (ن) with a Sukoon/Jazm on it. The Noon Saakin can take place in the middle or end of any word. Tanween and Noon Saakin are read in one of the forms of Ikhfa, Izhar, Idghaam, and Iqlaab.
Noon Saakin examples:
- الْإِنسَان (al-insan) — another example of Noon Saakin sitting inside a word rather than at its end.
- مِنْ (min) — a standalone word ending in Noon Saakin.
- يَنصُرُ (yansuru) — Noon Saakin appears in the middle of the word.
What is Tanween?
The change made by Tanween on the word is called “nunation.” Tanween signs add an “n” sound to the end of a word in certain circumstances. Tanween occurs as a double Fatha (Nasb, two lines above the word), a double Kasra (Jar, two lines under the word), or a double Dhamma (Raf). If Tanween is attached to the next letter, it is read; if the reciter pauses on it, it is not read.
The stances of Tanween in the word are as follows:
- When a pause is made after a word ending in Tanween Al-Fatha, the Tanween is turned into an Alif and stopped by lengthening it the amount of an Alif.
- There will be no Alif in Tanween Al-Fath if the last letter of the word is a Taa Marbutah (ة).
To see both cases in the Quran:
“عَلِيمًا حَكِيمًا”
(Aleeman Hakeema) — Surah An-Nisa (4:11)
— when a reciter pauses after this Tanween Fatha, it is read عَليمًا حكيما with the Alif sound stretched out.
Compare that with:
“جَنَّةً وَحَرِيرًا“
(Jannatan wa Hareera) — Surah Al-Insan (76:12)
— here the word ends in Taa Marbutah (ة), so on pausing it becomes جَنَّة with no Alif added at all.
How Many Noon Saakin and Tanween Rules Are There?
When we talk about Tanween and Noon Saakin rules, there are four related ones we should mention:
- Izhar
- Iqlaab
- Idghaam
- Ikhfaa
Noon Sakinah and Tanween are read in one of these four forms. Let’s examine what these Noon Saakin rules are and how we can distinguish the Tanween and Noon Saakin rules from each other.
Noon Saakin Rules
Each of the four rules below is triggered by a specific set of Arabic letters coming directly after a Noon Saakin or Tanween — and each one changes how that sound is pronounced in a distinct way. Knowing the trigger letters by heart is what lets a reciter apply the correct rule instantly, without pausing mid-ayah to think it through.
1. Izhar
The word “Izhar” means, in the dictionary, to explain something or to make something clear. If one of the throat letters, known as “Huroof Halaqiyya,” comes after Noon Sakinah or Tanween, we are talking about Izhar.
- The Huroof Halaqiyya are: ء – هـ – ع – ح – غ – خ
- When we pronounce the letter N clearly, with no merging or nasal stretch, we are applying the Izhar rule.
Examples:
“مِّنْ خَوْفٍ”
(min khawfin) — Surah Quraysh (106:4)
— Noon Saakin is followed by خ, so it is pronounced clearly with no merging or nasal stretch.
“سَمِيعٌ عَلِيمٌ“
(samee’un ‘aleem) — Surah Al-Baqarah (2:181)
— here it is the Tanween, not a Noon Saakin, that is followed by ع, and the same clear pronunciation applies.
2. Iqlaab
If there is a letter Baa (ب) after the Noon Saakin or Tanween, here we have Iqlaab. Changing the sound of a Noon Saakin or Tanween into a Meem is the definition of Iqlaab. All you have to do is stretch the sound to add Ghunna.
- Iqlaab occurs only before one letter: Baa (ب).
- The letter Meem usually gives us a visual sign in the Mushaf to recognize this rule — it’s all about turning one letter’s sound into another.
“مِن بَعْدِ”
(mim ba’di) — Surah Al-Baqarah (2:27)
— the Noon Saakin turns into a light Meem sound before ب.
“سَمِيعًا بَصِيرًا”
(samee’am baseera) — Surah An-Nisa (4:58)
— the same conversion happens here with Tanween instead of Noon Saakin.
3. Idghaam
The third of the Noon Saakin rules is called Idghaam — merging one letter’s sound into the next. It splits into two types depending on which letter follows the Noon Saakin or Tanween:
a. With Ghunna:
if one of the letters ي – م – ن – و comes after Tanween or Noon Sakinah, it becomes Idghaam with Ghunna (a nasal sound) held for 2 counts. Example:
“فَمَن يَعْمَلْ“
(famay ya’mal) — Surah Az-Zalzalah (99:7)
— the Noon Saakin merges into ي and is held for 2 counts with a nasal sound.
b. Without Ghunna
if the letter Lam or Ra comes after Tanween or Noon Sakinah, it is Idgham without Ghunna — pronounced without stretching, passed through quickly.
Example:
“مِن رَّبِّهِمْ”
(mir rabbihim) — Surah Al-Baqarah (2:5)
— the Noon Saakin merges into ر instantly, with no nasal sound at all.
A Tanween case follows the same rule:
“هُدًى لِّلْمُتَّقِينَ”
(hudal lilmuttaqeen) — Surah Al-Baqarah (2:2)
— the Tanween merges into ل in the same quick, non-nasal way.
4. Ikhfaa
From the Noon Saakin rules listed so far, there are fifteen letters left that we haven’t mentioned yet. Ikhfaa occurs when one of these fifteen letters comes after a Tanween or Noon Sakinah.
- The remaining fifteen letters are: ت – ث – ج – د – ذ – ز – س – ش – ص – ض – ط – ظ – ف – ك – ق
- While applying this rule, the tongue should not stick to the palate or upper front teeth — there should be a slight gap in between.
- The sound is released from both the mouth and the nasal passages together.
Examples:
“مِن دُونِ اللَّهِ”
(min dooni Allah) — Surah Al-Baqarah (2:23)
— the Noon Saakin before د is concealed, held with a light nasal buzz instead of being pronounced clearly or fully merged.
“قَوْلًا سَدِيدًا”
(qawlan sadeeda) — Surah Al-Ahzab (33:70)
— the same partial concealment happens here with Tanween before س.
Quick Comparison – The 4 Noon Saakin Rules
With all four rules explained individually, it helps to see them lined up side by side — the table below is a quick reference you can glance at while practicing recitation.
| Rule | Trigger Letters | What Happens to the Sound |
|---|---|---|
| Izhar | ء ه ع ح غ خ | Pronounced clearly, no merging, no nasal stretch |
| Iqlaab | ب | Changes into a light Meem sound with Ghunna |
| Idghaam with Ghunna | ي م ن و | Merges into the letter, held 2 counts with a nasal sound |
| Idghaam without Ghunna | ل ر | Merges into the letter instantly, no nasal sound |
| Ikhfaa | The remaining 15 letters | Partially concealed, sound comes from mouth and nose together |
Common Mistakes When Applying Noon Saakin and Tanween Rules
A few errors come up repeatedly with students working through these rules, and knowing them in advance saves a lot of correction time later:
- Cutting the Ghunna short in Ikhfaa and Idghaam with Ghunna — reciters often treat the nasal sound as optional decoration rather than the fixed 2-count hold it actually is.
- Confusing Idghaam without Ghunna (ل and ر) with Ikhfaa — both feel like the Noon Saakin “disappears,” but the difference is that Idghaam without Ghunna has zero nasal sound, while Ikhfaa keeps a light nasal buzz throughout.
- Applying Iqlaab without actually converting the letter to a Meem sound — some reciters just soften the Noon instead of fully changing it, which changes the rule being applied.
Practicing each rule on isolated words before reading full ayahs is what usually fixes all three mistakes.

What Are Shaddah & Mushaddad?
Now that we’ve covered all the Noon Saakin rules with simple examples, it’s worth going over the meaning of Noon Mushaddad and how to read it correctly when reciting the Book of Allah SWT.
- In the Arabic language, there are diacritics: Fatha, Dammah, and Kasrah.
- Shaddah is also one of these diacritics — it brings together two of the same letter.
- The first letter carries no vowel, and the second carries a vowel.
It is also advisable to check our detailed blogs about the Meem Sakinah rules with examples as well as the Laam Sakinah rules and how to master them in order to make everything clearer.
Noon Mushaddad and Meem Mushaddad Examples
Noon and Meem are called the letters of Ghunna. As mentioned while explaining the Noon Saakin rules, Ghunna is a nasal sound. When we see the letter Noon or Meem carrying a Shaddah, we hold it for a period of time with Ghunna.
Briefly: if we come across a Noon or Meem Mushaddad (with a Shaddah sign on it), we must apply Ghunna for 2 beats.
Examples:
“إِنَّ اللَّهَ عَلَىٰ كُلِّ شَيْءٍ قَدِيرٌ”
(Inna Allaha ‘ala kulli shay’in Qadeer) — Surah Al-Baqarah (2:20)
— the doubled Noon in “إِنَّ” is held with Ghunna for 2 counts.
“ثُمَّ إِنَّكُم بَعْدَ ذَٰلِكَ لَمَيِّتُونَ”
(Thumma innakum ba’da dhalika lamayyitoon) — Surah Al-Mu’minoon (23:15)
— the doubled Meem in “ثُمَّ” is held the same way.

Conclusion
The rules of Noon Saakinah and Tanween in Tajweed govern how these sounds are pronounced during Quranic recitation:
- Izhar — the Noon Saakinah or Tanween is pronounced clearly when followed by throat letters.
- Iqlaab — Noon Saakinah or Tanween changes into a Meem sound with nasalization when followed by the letter Baa.
- Idghaam — the sound merges into the next letter, either with or without nasalization, depending on the following letter.
- Ikhfaa — the Noon Saakinah or Tanween is partially concealed, creating a blend between the sounds, and applies to the remaining 15 letters.
Understanding and applying these Noon Saakin rules ensures proper Quran recitation, maintaining both clarity and melody in accordance with Tajweed principles.

Frequently Asked Questions About Noon Saakin Rules
Here are quick answers to the questions readers most often ask about Noon Saakin and Tanween rules:
1. What Is Noon Saakin?
Noon Saakin is a Noon letter (ن) carrying a Sukoon, meaning it has no vowel of its own. It can appear in the middle or at the end of a word, and it is always read according to one of four rules: Izhar, Iqlaab, Idghaam, or Ikhfaa.
2. What Are the Four Noon Saakin Rules?
The four Noon Saakin rules are Izhar (clear pronunciation before throat letters), Iqlaab (changing into a Meem sound before ب), Idghaam (merging into the next letter, with or without Ghunna), and Ikhfaa (partial concealment before the remaining 15 letters).
3. What Is the Difference Between Noon Saakin and Tanween?
Noon Saakin is a fixed Noon letter with a Sukoon written into the word itself, while Tanween is a doubled vowel mark (two Fathas, two Dammas, or two Kasras) added at the end of a word to give it an “n” sound. Both are governed by the same four rules.
4. What Is Ikhfaa in Tajweed?
Ikhfaa is the rule applied when a Noon Saakin or Tanween is followed by one of 15 specific letters. The sound is neither fully pronounced nor fully merged — it is partially concealed, with the tongue held slightly away from the palate and the sound released through the nose and mouth together.
5. Why Does Iqlaab Change Noon Into a Meem Sound?
Iqlaab happens specifically before the letter Baa (ب), because pronouncing a Noon Saakin directly before a Baa is difficult on the tongue. Converting it into a light Meem sound with Ghunna makes the transition smoother without changing the meaning of the word.
