Learn all about the rules of Ikhfaa in Tajweed and how to practice them.

You will learn what is Ikhfaa; What are Ikhfaa letters? Al-Ikhfaa’s Letters with Examples and More.

“Ikhfaa” in Tajweed refers to concealing the sound of a letter, particularly An-noon As-sakinah or the Tanween sign, while maintaining the nasal sound (ghunnah) and hiding the letter behind the following sound. There are fifteen Ikhfaa letters, such as ش، س، ز، ذ، د، ج، ث، ت، ك، ق، ف، ظ، ط، ض، ص, which trigger Ikhfaa when preceded by An-noon As-sakinah or At-tanween.

Mistakes in Ikhfaa often involve incorrect duration of ghunnah or confusion between Haqiqi and Shafawi Ikhfaa. Recognizing Ikhfaa in the Quran involves identifying An-noon As-sakinah or At-tanween followed by specific letters. Understanding Ikhfaa is essential for proper recitation of the Quran according to Tajweed rules.

Learn All in details below.

What Is Ikhfaa?

The term Ikhfaa linguistically means to hide or cover a letter sound, in a way as if it is a silent letter. The Arabic word (Haqiqi) means real or obvious. 

The meaning of the linguistic term of Ikhfaa in Tajweed knowledge means to pronounce the sound of the Arabic letter (An- noon As-saknhah) or the sign (Harkat) Tanween in a way that is between Izhaar and idghaam, retaining the ghunnah sound clear out of the nose (a nasal sound) while concealing the sound of the letter (An-noon) behind the sound that comes after it.

In simple words: Ikhfaa is to hide the whole of a letter sound or some of it while you are pronouncing it. In other words, Ikhfaa is a path between Izzhar and Idghaam.

Note: Terms to Understand Before Completing: We have to know some Tajweed phonetics expressions and idioms in order to understand what is meant by Ikhfa, here are these idioms: 

Ghonnah:	Ghonnah is a nasal sound thatis produced when you utter the sound of the letter (N – ن) from your nose. In other words: It is to pronounce the sound of the Arabic letter (AL Noon) or (AL Meem), with a nasal sound from the nose for a period of approximately two seconds.
Izzhar:	Izhar is to make the sound of a certain letter completely clear and voiced.
Idghaam:	Idghaam is to mix or combine two sounds into one sound, the preceding sound with the sound that follows it.

What are the rules For Ikhfaa in Tajweed?

The Tajweed rule of Al-Ikhfaa is as follows: If any of the fifteen Arabic letters of Ikhfaa are preceded by An-noon As-sakinah or At-tanween, then, An-noon As-sakinah and At-tanween should be hidden when they are pronounced with making the sound of ghunnah for approximately two beats of seconds.

Sound Blending: 

The Noon sound is hidden and blended into the following letter, creating a nasal sound that’s neither fully pronounced as Noon nor fully merged with the next letter.

Nasalization: 

A nasal sound is produced (called Ghunna), but it’s softer than when fully pronounced.

Duration: 

The Noon Saakinah or Tanween sound lasts for half a beat (1 Alif).

No Full Pronunciation: 

The Noon is not articulated fully, but is subtly blended with the following letter.

Here are some examples from the Quran where Ikhfaa is applied:

مِنْ جَاءَ (min jaa’a) – Surah Al-Ahqaf (46:9)

The Noon Saakinah (ن) blends with the Jeem (ج), producing a nasal sound.

مِنْ قَبْلِ (min qabli) – Surah Al-Ahzab (33:17)

The Noon Saakinah (ن) blends with the Qaaf (ق), creating a nasal sound.

مِنْ شَرِّ (min shari) – Surah An-Nas (114:4)

The Noon Saakinah (ن) blends with the Sheen (ش), resulting in a nasal sound.

مِنْ فَمِهِ (min famihi) – Surah Al-Mujadila (58:11)

The Noon Saakinah (ن) blends with the Faa (ف), producing a nasal sound.

مِنْ رَحْمَتِهِ (min rahmatihi) – Surah At-Tawbah (9:71)

The Noon Saakinah (ن) blends with the Raa (ر), creating a nasal sound.

What Are Ikhfaa Letters (Haqiqi)?

The Arabic letters of Al-Ikhfaa Al-Haqiqi (that means to be the clear and obvious hidden pronunciation of letters) are fifteen Arabic letters of the Arabic language alphabet.  If any letter of these fifteen letters comes after An-noon As-Sakinah or At-tanween, there will be Ikhfaa Haqiqy (clear).

Here are the fifteen Arabic letters of Al-Ikhfaa:

ش	س	ز	ذ	د	ج	ث	ت
####	ك	ق	ف	ظ	ط	ض	ص

How To Remember Ikhfaa letters?

There are three kinds of tips that can always assist you in reminding the fifteen letters of Al-Ikhfa

Here they are:

1. The Rest Of The Letters After Al-Izhaar, Idghaam, And Iqlab Letters

In Direct Opposition to Al-Izhaar, Idghaam, and Iqlab letters 

When you Know that the letters of Al-Izhaar are:

خ

غ

ح

ع

ه

ء

And the Arabic letters of Idghaam are:

ن

و

ل

م

ر

ي

And when you memorize that the letter of Iqlab ruling is (ب)

Then, the remaining letters of the Arabic alphabet are fifteen letters.These fifteen letters are Al-Ikhfaa’s letters.

2. Divide Ikhfaa Letters Into Groups:

Memorizing Al-Ikhfaa’s letters by dividing them into groups, using the fifteen pieces of the five figures of one hand, which form fifteen letters.

3. Memorize An Arabic Sentence:

The last tip is to memorize the following Arabic sentence, the letters of Al-Ikhfaa are at the beginning of each word of this Arab sentence.

Here the Arabic sentence is:

صِف ذا ثَنَا كَمْ جَادَ شَخْصٌ قَدْ سَمَا دُمْ طَيِّبًا زِدْ في تُقًي ضَعْ ظَالِمًا

Types Of Ikhfaa:  Ikhfaa’ Haqiqy (Clear) And Ikhfaa’ Shafawi Difference: 

There are two types of Ikhfaa: Ikfaa Haqiqi and Ikhfaa Shafawi. The difference between Ikhfaa’ Haqiqy (clear) and Ikhfaa’ shafawi (oral) has to do with the way each one is pronounced.

1. Ikhfaa Haqiqi:

Al-Ikhfaa Al Haqiqi is to conceal the sound of An-noon As-sakinah or At-tanween if any letter of the fifteen letters comes after them.

2. Ikhfaa Shafawi:

Ikhfaa Shafawi is to conceal or hide the sound of the Arabic letter Al-Meem As-sakinah (م) withholding Al-ghunnah sound in case it is followed by the Arabic letter (ب).

Al-Ikhfaa Ash-shafawi is named so because the place of articulation (voice Makhrij) of the Arabic letter “Meem” and the Arabic letter “Baa” are the same. They are pronounced by the lips.

 Here are some examples:

• تَرْمِيهِم بِحِجَارَةٍ
• وَهُم بِالْآخِرَةِ

How Can We Pronounce Al-Ikhfa Letters?

The correct pronunciation of the Ikhfaa rule is to articulate An-noon or Tanween sound by placing the front of your tongue in the upper part of your mouth with making Al Ghunnah Sound. But it is worth mentioning that You should avoid letting the tip of tongue touch the upper part of your mouth while you are articulating Ghunnah.

Ikhfaa’s ghunnah sound ruling is the same as the letter that comes after an-noon or At-tanween, regarding the heaviness or the lightness of the letter that comes after, which means that the Ikhfaa’s ghunnah sound is heavy if it is followed by a heavy letter and it is light if it is followed by a light letter.

So if we want to put it in steps, they are as follows:

Start With Nasal Sounds:

It should not be completely open during the day, or fresh. Instead, medial and intermediate consonants can be combined without pronouncing them at all to produce a nasal sound.

It’s Simple And Subtle:

Transitions between the mid and back vowels must be made smoothly, nasally without difficulty. This means it is not as strong as Idghaam (where the letters are completely merged) but more hidden.

Keep The Mouth Position In Mind:

For example, when pronouncing “مِنْ جَاءَ” (min jaa’a), the Noon is blended into the Jeem, and your tongue should not press hard against the roof of the mouth as it would in a regular Jeem sound, but instead, there is a nasal resonance.

How To Recognize The Ikhfaa Rule In The Mosihaf?

We can easily identify Al-Ikhfaa while we are reading the Arabic version of the holy Quran by one of the following means:

• When we meet the Arabic letter An-Noon which is called (naked Noon) it means Noon without any of the phonetic signs (Kasrah, Dhammah, and Fatt-ha). That means there is nothing above it at all.
• When we find At-tanween above or under a letter (which means double of fatt-ha, double of kasrah, or double of Dhammah) and the letter that follows has no shaddah (an Arabic phonetic sign).

Examples:

•     مِنْ جَهَنَّمَ (min jahannama) Surah Al-Mulk (67:6)

 Noon Saakinah (ن) is followed by Jeem (ج), so the Ikhfaa rule applies. The Noon sound is blended into the Jeem with a nasal sound.

•     مِنْ وَرَائِهِ (min wara’ihe) Surah Al-Imran (3:53)

Noon Saakinah (ن) is followed by Waw (و). The Ikhfaa rule blends the Noon into the Waw with a nasalized sound.

What Is The Main Reason Behind The Sound Of Al-Ikhfaa?

The reason that forces us to articulate the sound of Al-Ikhfaa is that the position of articulations (makharaj) of al-ikhfaa’s fifteen letters of the Arabic letter, Al-Noon, are neither the same as Al-Idghaam place of articulation nor Al-Izhaar place of articulation.

Thus, we are forced to pronounce them somehow between the way of Al-Idghaam articulation and Al-Izhaar articulation.

Let’s explain the reasons in the main sentence:

• Smooth Transition Between Sounds
• Nasal Sound (Ghunna)
• Phonetic Balance
• Avoiding Harshness
• Enhancing Recitation Fluency

The main reason behind the sound of Ikhfaa is to achieve a smooth, nasalized transition between the Noon Saakinah (or Tanween) and the following letter. This blending softens the Noon and avoids a harsh break in the recitation, ensuring that the flow of the Quran remains fluid, rhythmic, and harmonious while maintaining the subtle resonance of the Noon sound.

The Three Levels of Ikhfaa in Tajweed:

Al-Ikhfaa has three levels, it mainly depends on the positions of articulation of the Arabic letter “An-noon” or the Arabic phonetic sign “At–tanween“. So, there are three kinds or levels of Al-Ikhfaa rule. They are as follows:

1. The High Level Of Al-Ikhfaa:

The high degree of ikhfaa occurs when An-noon As-sakinah or At-tanween Sign is followed by the Arabic letters (د ، ت ط).

In this case, Al-Ikhfaa turns to be- to some extent- similar to Al-Idghaam because the positions of articulations (Makharaj) of these three Arabic letters are adjacent to the position of articulation (makhraj) of the Arabic letter An-noon or the Arabic phonetic sign, At-tanween.

2. The Low Degree Of Al-Ikhfaa:

The low degree of Al-Ikhfaa rule happens when An-noon As-sakinah or At-tanween Sign is followed by two Arabic letters which are (ق ، ك). 

In this case, it is- to some extent- similar to the rule of Al-Izhaar because the places of articulation to these two Arabic letters are not close to the position of articulations of An-noon and At-tanween sign.

3. The In-Between Degree Of Al-Ikhfaa:

This case happens when one of the other ten Arabic letters comes after An-noon or At-Tanween. That is because the positions of articulation are neither remote nor adjacent to the position of articulations of An-noon As-sakinah or At-tanween.

Common Mistakes Relating To Al-Ikhfaa Rule:

Common mistakes concerning the Ikhfaa rule while performing Tajweed diminish the clarity and beauty of Quranic recitation. Some of the most frequent ones, along with explanations for them to be avoided while applying Ikhfaa, are given below:

1. Over-articulating Noon ن

Mistake: Some reciters might pronounce the Noon Saakinah ن or Tanween ً ٍ ٌ too clearly, or with a full Noon sound when followed by one of the Ikhfaa letters, as if they were pronouncing the Noon fully, as in Izhaar.

Correct Way: The Noon should not be fully pronounced, but it should be nasalized and merged into the next letter to give a soft, hidden sound that’s neither fully Noon nor completely merged with the following letter.

Example: In مِنْ جَاءَ (min jaa’a), you should not say the Noon as a full “n” sound and then move to Jeem (ج). It must be nasalized, just like min jaa’a.

2. Not Applying Nasalization (Ghunna)

Mistake: Some reciters might not pronounce the nasal sound while performing Ikhfaa. The Noon Saakinah, ن, has to be nasal, and this is part of the Ikhfaa sound. The failure to nasalize it will result in wrong pronunciation.

Correct Way: Make sure that the Noon is not only hidden but also carries the nasalized sound, which usually is a light hum coming from the nose.

Example: In مِنْ فَجْرِهِ (min fajrihi), the Noon should be blended softly into Faa (ف), with a nasal sound. Missing the nasalization would result in less accurate recitation.

3. Pronouncing The Ikhfaa Letters Too Sharply

Mistake: Another mistake which is common is when one articulates the Ikhfaa letters (such as Jeem (ج), Khaa (خ), Sheen (ش) etcetera) too forcefully, or with a stress in pronunciation. This doesn’t allow the Noon Saakinah (ن) and the letter that comes after it to blend in smoothly.

Correct way: The Ikhfaa letters must be clear but with a soft articulation, keeping the Noon Saakinah softly merged into the following letter without letting a sharp distinction occur between them.

Example: When saying مِنْ شَرِّ, Noon is required to blend with Sheen (ش) yet in pronunciation it mustn’t become “min” with the strong “sha”, which means Noon has to get into Sheen easily and smoothly.

4. Lack Of Recognition Of Ikhfaa Letters

Mistake: Some reciters may not pronounce the Ikhfaa letters at all and either apply another rule or mispronounce the Noon Saakinah when followed by one of the 15 Ikhfaa letters.

Correct Way: Be constantly aware of the Ikhfaa letters, the 15 letters previously listed, and apply your rule every time Noon Saakinah or Tanween is followed by one of them.

Example: مِنْ قَبْلِ (min qabli), here ن (Noon Saakinah) is followed by ق (Qaaf), so it should be pronounced as an Ikhfaa. If this rule is misapplied, there will be a mistake in pronunciation.

5. Incorrect Length Of Ikhfaa-Using Wrong Time

Mistake: The nasal sound sometimes is elongated for the wrong duration in Ikhfaa by some readers. Ikhfaa should last for half a beat (about 1 Alif), but too many people either stretch it too long as in Idghaam or cut it too short.

Correct: The nasal should be held for a brief, appropriate length — about half a beat — to keep the right balance between clarity and smoothness.

Example: In مِنْ مَالِهِ (min maalihi), the nasalization should be subtle and for the right duration of half a beat, not prolonged as in Idghaam.

6. Ikhfaa Combined With Other Rules

Mistake: Some of the reciters mix up the Ikhfaa rule with some other rules in Tajweed such as Idghaam-where the Noon completely is merged into the next letter, or Izhaar where the Noon is clearly pronounced.

Correct: Practice distinguishing between Ikhfaa (blending the Noon with a nasal sound) and Idghaam (complete merging of the Noon with the next letter) or Izhaar (clear pronunciation of the Noon).

Example: In مِنْ جَاءَ min jaa’a, Noon is to be blended with Jeem ج Ikhfaa, not as in Izhaar fully pronounced nor in Idghaam, which is a complete merge.

7. Confusing The Ikhfaa Rule With Iqlab

Mistake: Sometimes, the Ikhfaa rule is confused with the Iqlab. In Iqlab, when Noon Saakinah is followed by the letter Baa (ب), the Noon is pronounced as Meem (م). Ikhfaa occurs with those 15 specified letters and consists of a nasalized blend.

Correct Way: Make sure to distinguish between Ikhfaa and Iqlab according to the letter that comes after the Noon Saakinah.

Example: In مِنْ بَعْدِ (min ba’di), the rule of Iqlab is applied, where the Noon is pronounced as a Meem sound. On the other hand, Ikhfaa would be applied when the Noon is followed by one of the 15 Ikhfaa letters.

Examples Of The Ikhfaa Rule:

Test your proficiency! As you have read this article about the rules of Al-Ikhfaa, you can now test how good you are in this Tajweed rule.

Find where Al-Ikhfaa should be done in the following Qur’an verses

Verse Number 1:

“إِنْ تَسْتَفْتِحُوا فَقَدْ جَاءَكُمُ الْفَتْحُ ۖ وَإِنْ تَنْتَهُوا فَهُوَ خَيْرٌ لَكُمْ ۖ وَإِنْ تَعُودُوا نَعُدْ وَلَنْ تُغْنِيَ عَنْكُمْ فِئَتُكُمْ شَيْئًا وَلَوْ كَثُرَتْ وَأَنَّ اللَّهَ مَعَ الْمُؤْمِنِينَ”
“If you desire a verdict, the verdict has come to you. And if you desist, it would be best for you. And if you return, we will return; and your troops, however numerous, will not benefit you. God is with the believers.”

Surah Al-Anfal verse, Number 19.

Verse Number 2:

” وَبَشِّرِ الَّذِين آمَنُواْ وَعَمِلُواْ الصَّالِحَاتِ أَنَّ لَهُمْ جَنَّاتٍ تَجْرِي مِن تَحْتِهَا الأَنْهَارُ كُلَّمَا رُزِقُواْ مِنْهَا مِن ثَمَرَةٍ رِّزْقًا قَالُواْ هَذَا الَّذِي رُزِقْنَا مِن قَبْلُ وَأُتُواْ بِهِ مُتَشَابِهًا وَلَهُمْ فِيهَا أَزْوَاجٌ مُّطَهَّرَةٌ وَهُمْ فِيهَا خَالِدُون”َ (سورة البقرة.)
“Give good news ˹O Prophet to those who believe and do good that they will have Gardens under which rivers flow. Whenever provided with fruit, they will say, “This is what we were given before,” for they will be served fruit that looks similar but tastes different. They will have pure spouses;1 and they will be there forever.”

Surah AL-Baqarah. Verse, Number 25

Conclusion:

The term “Ikhfaa” in Tajweed refers to the act of hiding or covering the sound of a letter, specifically An-noon As-sakinah or the Tanween sign, while maintaining the nasal sound (ghunnah) and concealing the sound of the letter behind the following sound. Ikhfaa serves as a middle ground between Izhaar and Idghaam. There are fifteen letters known as Ikhfaa letters, and when preceded by An-noon As-sakinah or At-tanween, Ikhfaa should be applied.

These letters include ش، س، ز، ذ، د، ج، ث، ت، ك، ق، ف، ظ، ط، ض، ص. Ikhfaa can be remembered by dividing the letters into groups, using mnemonic sentences, or recognizing their positions in relation to other Tajweed rules. There are two types of Ikhfaa: Haqiqi (clear) and Shafawi (oral), distinguished by their pronunciation.

Mistakes in Ikhfaa often involve incorrect duration of ghunnah, confusion between Haqiqi and Shafawi Ikhfaa, and stressing the ghunnah sound. Recognizing Ikhfaa in the Quran involves identifying An-noon As-sakinah or At-tanween followed by certain letters. Understanding Ikhfaa is crucial for proper recitation of the Quran according to Tajweed rules.
