Difference Between Ikhfaa, Idgham, Izhar, And Iqlab: The main difference is that Ikhfaa partially conceals with nasalization, Idgham merges letters fully with nasalization, Izhar pronounces clearly without nasalization, and Iqlab changes noon saakinah or tanween to meem with nasalization.
After learning the rules of Noon and Meem Sakinah, which are Idgham, Izhar, Ikhfa, and Iqlab, in this article we will thoroughly review each type and identify the main differences between these rules. Get ready for an enjoyable journey with Sheikh Academy in the science of Tajweed to recite the Quran with beauty and precision.
Summary of the Difference Between Ikhfaa, Idgham, Izhar, And Iqlab:
The main difference between Ikhfaa, Idgham, Izhar, and Iqlab is their effect on the pronunciation of noon saakinah or tanween: Ikhfaa involves partial concealment with nasalization when followed by specific letters, Idgham entails complete merging into the next letter, creating a single stressed letter with nasalization, Izhar requires clear articulation without nasalization when followed by throat letters, and Iqlab changes the noon saakinah or tanween into a meem with nasalization when followed by the letter “ba.

Izhar | Clear pronunciation of noon (ن) or tanween without nasalization (ghunnah). The noon and tanween are articulated clearly without merging or changing. | ء (Hamza), هـ (Haa), ع (Ain), ح (Haa), غ (Ghayn), خ (Khaa) | – مَنْ ءامَنَ (At-Tawba 18)<br>- مِنْ عِلْمٍ (An-Najm 28)<br>- مِنْ خَيْرٍ (Al-Qasas 24) |

Ikhfaa | A state between Izhar and Idgham where the noon is not fully articulated nor completely merged. It is pronounced with a nasal sound (ghunnah) and without stressing the letter. | ص (Saad), ذ (Dhaal), ث (Thaa), ج (Jeem), ش (Sheen), ق (Qaaf), س (Seen), د (Daal), ط (Taa), ز (Zaay), ف (Faa), ت (Ta), ض (Daad), ظ (Dhaa) | – يَنْصُرُونَ (yansuroon)<br>- مَنْ صَلْصَالٍ (min ṣalsāl)<br>- ريحاً صَرْراً (rihan sararan)<br>- أأنذرتهم (a’anthartahum)<br>- من ذا الذي (man dhā al-ladhī) |
Let’s discuss them in detail below:
Definition of Idgham:
Idgham is the merging of one letter into another.it happens when meeting a letter (saken) with a vowel letter (mutaharek) such that they become a single stressed (shaddah) letter, with the tongue rising once when pronouncing them, equivalent to the weight of two letters.
Idgham letters:
ي (Ya),ر (Ra), م ( Meem),ل ( Lam), و ( Waw), ن ( Noon).
If one of these six letters (Ya, Ra, Meem, Lam, Waw, Noon) occurs after a Noon Sakinah, with the condition that the Noon is at the end of a word and one of these letters is at the beginning of the next word, or after Tanween (which only occurs between two words), Idgham is the rule.
Then, Idgham is incomplete (Naqis) with ي( Ya) and و ( Waw), and complete (Kamil) with the rest of the letters in (Ra ر -Meem م -Lam ن – ل Noon).
Examples of Idgham from holy Quran:
Letters | Example | Explanation | Surah | Ayah |
و (waw), ن (Noon), | مِن وَلِي | “ن” merges into “و” with a nasal sound. | Al-Baqarah | 107 |
ٍ(tanween) , و (Waw) | وَلِيٍّ وَلاَ | “Tanween” merges into “و” with a nasal sound. | Al-Baqarah | 107 |
ي (ya) , ن (noon) | فَمَن يَـعْمَلْ | “ن” merges into “ي” with a nasal sound. | Az-Zalzalah | 7 |
ً (tanween) , ي (Ya) | خَيْراً يَرَهُ | “tanween” merges into “ي” with a nasal sound. | Az-Zalzalah | 7 |
ن (Noon), ن (Noon), | مِن نَّـفْعِهِمَا | Mergeing two “ن” into one “ن” with a nasal sound. | Al-Baqarah | 219 |
م (Meem) , ن (Noon) | مِن مَّـاء | “ن” merges into “م” with a nasal sound. | Ibrahim | 16 |
ً (Tanween) , م (Meem) | وَلَيَكُونـاً مِّنَ | “Tanween” merges into “م” with a nasal sound. | Yusuf | 32 |
ً (tanween) , ن (Noon) | يَوْمَئِذٍ نَّـاعِمَةٌ | “tanween” merges into “ن” with a nasal sound. | Al-Ghashiya | 8 |
What is Izhar?
Al-Izhar (Clear Articulation) is the pronunciation of the noon (ن) clearly from its place of articulation without nasalization (ghunnah). Izhar means that the noon saakinah or the tanween is pronounced clearly without complete nasalization, and then the izhar letter is pronounced without any pause or break between them.
The reason for the clear pronunciation of the noon and the tanween before the six izhar letters is the separation between the articulation point of the noon and the tanween, and the articulation point of these letters. The noon and the tanween are articulated from the tip of the tongue, while the six letters are articulated from the throat, creating a clear distance between their articulation points.
Letters of Izhar:
Izhar letters are six: (ء, هـ, ع, ح, غ, خ), which are called the throat letters (letters of the throat). When any of these six letters comes after the noon, whether within the same word or in two separate words (where the noon is at the end of the first word and the izhar letter is at the beginning of the second word), and when these letters come after the tanween, it is obligatory to pronounce the noon and the tanween clearly. This is called Izhar Halqi (Throat Izhar) because its six letters originate from the throat.
Examples of Izhar from the holy Quran:
Letters | Example | Explanation | Surah | Ayah |

Al-Iqlab Definition:
Al-Qalb (إقلاب – Substitution): In technical terms, it means replacing one letter with another while considering nasalization (ghunnah) and concealment (ikhfa) in the substituted letter. Here, it specifically refers to the transformation of a noon saakinah (ن) or tanween (ً/ٍ/ٌ) into a meem (م). There is one letter associated with this rule, which is the letter “ba” (ب).
If a “ba” follows a noon saakinah, whether in the same word, in two separate words, after tanween, or after the light noon of emphasis (ن) connected to the present tense verb resembling tanween, the noon saakinah, tanween, and the noon of emphasis must be changed into a pure meem.
Examples of Al-Iqlab from the holy Quran:
In the verse: “( أَنبِئُونِي )”[Al-Baqarah : 31] , the noon is changed to a meem. Also, in the verse: “( مِنْ بَعْدِهِمْ )” [Al Muminoon : 31] , the noon saakinah is changed to a meem and pronounced with nasalization (ghunnah). Additionally, in the verse: “( وَاللَّهُ عَلِيمٌ بِذَاتِ الصُّدُورِ)” [Al Taghabun : 4] , and in His saying: “( لَنَسْفَعًا بِالنَّاصِيَةِ)” [Al-‘Alaq: 15], the noon of emphasis is pronounced as a meem with nasalization (ghunnah).
It is clear from the definition of Iqlab that it is realized through three aspects:
- Changing the noon saakinah or tanween into a meem.
- Concealing this meem in the presence of the letter ba (ب) .
- Applying nasalization (ghunnah) with this concealment.

Al-Ikhfaa Definition
The other rule for the noon saakinah and tanween is Ikhfa. Ikhfa is a state between Izhar (clear pronunciation) and Idgham (merging), where the pronunciation of the noon is neither fully articulated like in Izhar, nor completely merged like in Idgham, which requires assimilation between the merged letter and the merging letter.
The letters of Ikhfaa:
There are fifteen Ikhfa letters: (ص، ذ، ث، ج، ش، ق، س، د، ط، ز، ف، ت، ض، ظ). When one of these letters follows a noon saakinah or tanween, the rule of Ikhfa is applied by pronouncing the noon saakinah or tanween in a manner that is between Izhar and Idgham, along with nasalization (ghunnah) for two counts without stressing the letter. Ikhfa for the noon saakinah can occur within one word or across two words, while Ikhfa for tanween occurs only across two words.
How to realize Ikhfaa?
Ikhfa is realized through three aspects, as evident from its definition:
- Pronouncing the noon saakinah or tanween in real Ikhfa—or the meem saakinah in oral Ikhfa—in a manner between Izhar and Idgham.
- Not stressing the concealed letter, unlike in Idgham.
- Applying nasalization (ghunnah) matching the letter that follows, so that the nasal sound blends with the following letter.
The reason for Ikhfa with these letters is that they are neither as close to the noon and tanween as the Idgham letters, which necessitates merging, nor as distant as the Izhar letters, which necessitates clear pronunciation. Thus, Ikhfa is a middle state between Idgham and Izhar, where the actual noon or tanween sound is removed but its characteristic nasalization (ghunnah) remains. Oral Ikhfa occurs due to the similarity between the letters meem and ba, making pronunciation easier.
Examples of Al-Ikhfaa from holy Quran:
