Noon Sakin & Tanween

Learn the four rules of Noon Saakin and Tanween—Izhar, Idgham, Iqlab and Ikhfa—with letter groups, Arabic examples and guided Tajweed practice.

What Are Noon Saakin And Tanween?

Noon Saakin is the letter ن carrying Sukoon: نْ. It has no short vowel after it and may appear in the middle or at the end of a word.

Tanween is one of the double vowel endings ً ٍ ٌ. During continuous reading, each Tanween includes a light n sound even though a separate letter ن is not written.

The pronunciation of Noon Saakin or Tanween depends on the next pronounced Arabic letter. Tajweed organises the possibilities into four main rules:

Izhar — read the Noon sound clearly.

Idgham — merge it into the next letter.

Iqlab — change it towards a hidden Meem sound.

Ikhfa — conceal it between clarity and merging.

The correct rule is chosen by looking immediately after Noon Saakin or Tanween while continuing the recitation.

Noon Saakin And Tanween Are Not Identical In Writing

Noon Saakin is a written Noon:

نْ

Tanween is a double vowel mark at the end of a word:

ً ٍ ٌ

Both produce a Noon-like sound during connected reading, so they share the same four Tajweed rules. However, Tanween is not an extra written Noon. Do not add ن to the spelling of a word that already ends in Tanween.

The four rules apply during wasl, meaning continuous reading. If you make a proper stop on the first word, there is no connection to the following letter, and the Tanween n sound is not carried across the stop.

RULE 1: IZHAR HALQI — CLEAR PRONUNCIATION

Izhar means to make clear. Izhar Halqi applies when Noon Saakin or Tanween is followed by one of the six throat letters:

ء ه ع ح غ خ

These are Hamzah, Haa, Ain, Haa, Ghain and Khaa. Because their articulation points are in the throat and away from the Noon’s articulation point, the Noon sound is pronounced clearly without merging into the next letter.

Examples with Noon Saakin:

مِنْ هَادٍ — Noon Saakin followed by ه

مِنْ عِلْمٍ — Noon Saakin followed by ع

مِنْ خَيْرٍ — Noon Saakin followed by خ

أَنْعَمْتَ — Noon Saakin followed by ع inside one word

Examples with Tanween:

عَلِيمٌ حَكِيمٌ — Dammatain followed by ح

قَوْمٍ هَادٍ — Kasratain followed by ه

عَذَابٌ أَلِيمٌ — Dammatain followed by ء

For Izhar, give the Noon its clear articulation and normal nasal quality, then move to the throat letter. Do not merge the two letters and do not hold an extended two-count Ghunnah as if performing Idgham or Ikhfa.

Izhar Practice Method

First point to the Noon Saakin or Tanween. Next identify the throat letter. Read the Noon clearly, then pronounce the following letter from its correct Makhrij.

Practise slowly:

مِنْ هَا

مِنْ عِلْمٍ

مِنْ خَيْرٍ

عَلِيمٌ حَكِيمٌ

Avoid placing a pause between the two words merely to escape the rule. The sounds remain connected, but the Noon itself stays clear.

RULE 2: IDGHAM — MERGING

Idgham means merging. It applies when Noon Saakin or Tanween at the end of a word is followed by one of these six letters at the beginning of the next word:

ي ر م ل و ن

They are commonly collected in the word يَرْمَلُونَ. The Noon is not pronounced as a separate clear consonant; it blends into the transition to the following letter. Detailed study later distinguishes complete and incomplete forms of merging.

Idgham has two groups: with Ghunnah and without Ghunnah.

Idgham With Ghunnah

The four letters of Idgham with Ghunnah are:

ي ن م و

They are commonly collected in the word يَنْمُو. Merge the Noon Saakin or Tanween into the following letter and maintain Ghunnah for two counts.

Examples:

مَنْ يَعْمَلْ — Noon Saakin followed by ي

مِنْ مَاءٍ — Noon Saakin followed by م

مِنْ وَالٍ — Noon Saakin followed by و

غَفُورٌ وَدُودٌ — Tanween followed by و

يَوْمَئِذٍ نَّاعِمَةٌ — Tanween followed by ن

The original Noon is not read as a separate clear consonant before the Idgham letter. Blend the transition while preserving the required nasal sound.

Idgham Without Ghunnah

The two letters of Idgham without Ghunnah are:

ل ر

They are Lam and Raa. Merge Noon Saakin or Tanween directly into the following Lam or Raa without holding Ghunnah.

Examples:

مِنْ رَبِّهِمْ — Noon Saakin followed by ر

مِنْ لَدُنْهُ — Noon Saakin followed by ل

هُدًى لِّلْمُتَّقِينَ — Tanween followed by ل

غَفُورٌ رَّحِيمٌ — Tanween followed by ر

Do not pronounce a separate Noon and do not add a nasal hold. Move directly into the doubled Lam or Raa sound.

Important Same-Word Idgham Exception

Idgham normally requires Noon Saakin to be at the end of one word and the Idgham letter to begin the next word. When Noon Saakin and Yaa or Waw occur together inside certain words, the Noon remains clear. This is called Izhar Mutlaq.

The well-known Quranic words are:

الدُّنْيَا

بُنْيَانٌ

صِنْوَانٌ

قِنْوَانٌ

Do not merge the Noon into the Yaa or Waw in these words. Learn their clear pronunciation directly from a qualified teacher.

RULE 3: IQLAB — CONVERSION

Iqlab applies when Noon Saakin or Tanween is followed by only one letter:

ب

The Noon or Tanween sound changes towards a concealed Meem sound and is read with Ghunnah for two counts before Baa.

Examples:

مِنْ بَعْدِ — Noon Saakin followed by ب

أَنْبِئْهُمْ — Noon Saakin followed by ب inside a word

سَمِيعٌ بَصِيرٌ — Tanween followed by ب

سَمِيعًا بَصِيرًا — Fathatain followed by ب

In some Mushaf scripts, a small Meem sign may appear as a visual reminder, such as:

مِنۢ بَعْدِ

Do not pronounce a clear Noon before Baa, and do not insert a full separate Meem into the spelling. Produce the concealed Meem quality with controlled Ghunnah, then move into Baa. Follow your teacher’s method for the precise lip position.

RULE 4: IKHFA HAQIQI — CONCEALMENT

Ikhfa means concealment. It applies when Noon Saakin or Tanween is followed by any of these fifteen letters:

ت ث ج د ذ ز س ش ص ض ط ظ ف ق ك

Ikhfa lies between Izhar and Idgham. The Noon is not pronounced with complete clarity, but it is not fully merged into the next letter. Conceal the Noon sound, maintain Ghunnah for two counts, and prepare the mouth for the following letter.

Examples with Noon Saakin:

مِنْ تَحْتِهَا — followed by ت

مِنْ ثَمَرَةٍ — followed by ث

مِنْ قَبْلِ — followed by ق

مِنْ فَضْلِ — followed by ف

أَنْفُسَكُمْ — followed by ف inside one word

Examples with Tanween:

قَوْمًا ظَالِمِينَ — followed by ظ

شَيْءٍ قَدِيرٌ — followed by ق

رِيحًا صَرْصَرًا — followed by ص

Do not press the tongue into the complete Noon articulation as in Izhar. Keep the nasal sound controlled while moving towards the Makhrij of the next letter. The following letter must remain recognisable and must not acquire an extra vowel.

How To Choose The Rule Quickly

Use this decision process whenever you see Noon Saakin or Tanween:

Step 1: Confirm that you are continuing rather than stopping.

Step 2: Identify the next pronounced letter.

Step 3: If it is ء ه ع ح غ خ, use Izhar.

Step 4: If it is ي ر م ل و ن, use Idgham and select the correct Ghunnah group.

Step 5: If it is ب, use Iqlab.

Step 6: If it is one of ت ث ج د ذ ز س ش ص ض ط ظ ف ق ك, use Ikhfa.

Do not choose a rule from the appearance of the first word alone. The following pronounced letter determines the rule.

Compare The Four Sounds

Izhar: the Noon remains clear.

Idgham: the Noon merges into the next letter.

Iqlab: the Noon changes towards a hidden Meem before Baa.

Ikhfa: the Noon is concealed with Ghunnah before one of fifteen letters.

Listen to the same Noon or Tanween pattern with different following letters. Hearing the contrast is as important as memorising the letter lists.

Ghunnah And Timing

Ghunnah is a nasal sound whose resonance comes through the nasal passage. Idgham with Ghunnah, Iqlab and Ikhfa are commonly practised for two counts. Idgham without Ghunnah has no nasal hold. Izhar keeps the clear Noon with its normal quality rather than an extended Ghunnah.

A count should be steady and consistent, not rushed in one example and stretched in another. Learn the practical sound from a qualified Tajweed teacher because written transliteration cannot demonstrate correct nasal resonance.

A Fifteen-Minute Practice Routine

Minutes 1–3: Recite the four letter groups from memory.

Minutes 4–6: Point to the next letter and name the correct rule without reading.

Minutes 7–9: Read two examples from each rule slowly.

Minutes 10–11: Compare Idgham with and without Ghunnah.

Minutes 12–13: Compare clear Izhar with concealed Ikhfa.

Minute 14: Practise one Iqlab example and check the Ghunnah.

Minute 15: Record a mixed reading and note the rule that needs more work.

Common Beginner Mistakes

Looking only at Noon: Always inspect the next pronounced letter.

Using Ghunnah for every rule: Idgham without Ghunnah uses Lam and Raa, while Izhar keeps the Noon clear without an extended nasal hold.

Reading Iqlab as a clear Noon: Change towards the concealed Meem sound before Baa.

Writing an extra Meem: Iqlab changes pronunciation; it does not add a normal full Meem to the word.

Merging same-word exceptions: Keep the Noon clear in الدُّنْيَا, بُنْيَانٌ, صِنْوَانٌ and قِنْوَانٌ.

Making Ikhfa identical to Idgham: Ikhfa conceals the Noon without completely merging it into the next letter.

Ignoring a stop: A rule across two words is not connected when a valid stop is made between them.

Depending on transliteration: Read the Arabic signs and listen to a qualified teacher.

Practice Check

Can I recognise Noon Saakin and all three Tanween signs?

Can I name the six Izhar letters?

Can I divide the Idgham letters into with and without Ghunnah?

Can I remember that Iqlab has only the letter Baa?

Can I name or recognise all fifteen Ikhfa letters?

Can I identify the rule by looking at the next pronounced letter?

Can I maintain a steady two-count Ghunnah where required?

Can I keep the four same-word exceptions clear?

Lesson Summary

Noon Saakin and Tanween follow one of four rules during connected reading. Use Izhar before ء ه ع ح غ خ. Use Idgham before ي ر م ل و ن, with Ghunnah for ي ن م و and without Ghunnah for ل ر. Use Iqlab before ب. Use Ikhfa before ت ث ج د ذ ز س ش ص ض ط ظ ف ق ك. Identify the next pronounced letter, apply the correct rule with measured timing, and practise the sound directly with a qualified Tajweed teacher.
