Idgham is a key rule in Tajweed that helps improve fluency and accuracy in Quran recitation. It occurs when a Noon Saakin or Tanween is followed by specific letters, causing the sound to merge smoothly into the next letter. This rule ensures the recitation remains natural while preserving the correct pronunciation taught in the Quran.
Idgham Meannig
Idgham means merging one letter into another so smoothly that they become one sound. In Tajweed, this rule applies when a Noon Saakin (نْ) or Tanween (ً ٍ ٌ) is followed by specific letters. Among its types, Idgham with Ghunnah is the most commonly used, especially in daily recitation and Quran memorization. Mastering Idgham strengthens both pronunciation and overall Quran memorization quality.
For students aiming to perfect these rules at a deeper level, enrolling in an advanced tajweed course can provide structured guidance, expert correction, and practical application for flawless recitation.
Types of Idgham in Tajweed (Complete Breakdown)
There are different types of Idgham, each with its own method and conditions. Understanding these types, along with clear examples, helps learners avoid common mistakes and recite with confidence.
Idgham with Ghunnah (إدغام بغنة)
This type of Idgham includes merging the Noon Saakin or Tanween into the next letter with a nasal sound (ghunnah) held for about two counts. It occurs with four letters: ي، ن، م، و (gathered in the word ينمو).
1. Idgham of Noon Saakin into Ya (ي) with Examples
When Noon Saakin comes before Ya (ي), the Noon sound merges into Ya with a clear nasal tone.
Examples from the Quran:
- مِن يَقُولُ (Surah Al-Baqarah 2:8)
- مَن يَعْمَلْ (Surah An-Nisa 4:124)
How it works:
- The “نْ” sound is not pronounced clearly
- Instead, it blends into “ي” with ghunnah
2. Idgham of Noon Saakin into Noon (ن) with Examples
Here, the Noon Saakin merges into another Noon (ن), creating a stressed Noon sound with ghunnah.
Examples from the Quran:
- مِن نِّعْمَةٍ (Surah An-Nahl 16:53)
- مِن نَّاصِرِينَ (Surah Al-Baqarah 2:107)
Key point:
- The second Noon is emphasized (مشدد)
- Ghunnah is clearly applied
3. Idgham of Noon Saakin into Meem (م) with Examples
When Noon Saakin is followed by Meem (م), the sound merges into Meem with nasalization.
Examples from the Quran:
- مِن مَّالٍ (Surah Al-Imran 3:116)
- مِن مَّسَدٍ (Surah Al-Masad 111:5)
What happens:
- Noon sound disappears
- Meem is pronounced with ghunnah
4. Idgham of Noon Saakin into Waw (و) with Examples
In this case, Noon Saakin merges into Waw (و) with a soft nasal sound.
Examples from the Quran:
- مِن وَلِيٍّ (Surah Ar-Ra’d 13:11)
- مِن وَاقٍ (Surah Ar-Ra’d 13:34)
Quick breakdown:
- The Noon is absorbed into Waw
- Ghunnah remains for two counts
5. Idgham of Tanween into Ya (ي) with Examples
When Tanween (ً ٍ ٌ) is followed by Ya (ي), the Tanween sound merges into Ya with a clear ghunnah (nasal sound).
Examples from the Quran:
- عَلِيمٌ يَقُولُ (Surah Al-Baqarah 2:282)
- هُدًى يَهْدِي (Surah Yunus 10:35)
How it is applied:
- The “ن” sound of Tanween is not pronounced separately
- It smoothly blends into “ي” with ghunnah (2 counts)
6. Idgham of Tanween into Noon (ن) with Examples
Here, Tanween merges into Noon (ن), producing a stressed Noon with ghunnah.
Examples from the Quran:
- غَفُورٌ نَّعِيمٌ (Surah Luqman 31:8)
- سَمِيعٌ نَّصِيرٌ (Surah An-Nisa 4:134)
Key points:
- A doubled Noon (نّ) sound appears
- Ghunnah is clearly held and emphasized
7. Idgham of Tanween into Meem (م) with Examples
When Tanween is followed by Meem (م), it merges into Meem with nasalization.
Examples from the Quran:
- غَفُورٌ مَّحِيمٌ (commonly appears across verses, e.g., Surah Al-Baqarah 2:173 pattern)
- سَمِيعٌ مُّبِينٌ (Surah Ash-Shura 42:11)
Application:
- The Tanween sound disappears into Meem
- Meem is pronounced with ghunnah (2 counts)
8. Idgham of Tanween into Waw (و) with Examples
In this case, Tanween merges into Waw (و) with a soft ghunnah sound.
Examples from the Quran:
- غَفُورٌ وَدُودٌ (Surah Al-Buruj 85:14)
- رَحِيمٌ وَدُودٌ (pattern appears in multiple recitations)
Quick understanding:
- The Tanween blends into Waw
- A nasal sound is maintained for proper Tajweed.

Idgham without Ghunnah (إدغام بلا غنة)
This type of Idgham occurs when Noon Saakin (نْ) or Tanween (ً ٍ ٌ) is followed by Laam (ل) or Raa (ر). In this case, the Noon sound merges completely into the next letter without any nasal sound (ghunnah). The transition is direct and clean, which makes it different from Idgham with Ghunnah.
1. Idgham of Noon Saakin into Laam (ل) with Examples
When Noon Saakin comes before Laam (ل), the Noon is fully merged into Laam without ghunnah.
Examples from the Quran:
- مِن لَّدُنهُ (Surah An-Nisa 4:40)
- مِن لَّدُنْهُ أَجْرًا (Surah Al-Kahf 18:2)
How it is applied:
- The Noon sound is not pronounced
- Laam is stressed (لّ) without nasalization
2. Idgham of Noon Saakin into Raa (ر) with Examples
When Noon Saakin is followed by Raa (ر), it merges into Raa without ghunnah.
Examples from the Quran:
- مِن رَّبِّهِمْ (Surah Al-Baqarah 2:5)
- مِن رَّحْمَةٍ (Surah Aal-Imran 3:159)
Key point:
- The Raa becomes emphasized (رّ)
- No nasal sound is held
3. Idgham of Tanween into Laam (ل) with Examples
When Tanween is followed by Laam (ل), the Tanween merges fully into Laam without ghunnah.
Examples from the Quran:
- هُدًى لِّلْمُتَّقِينَ (Surah Al-Baqarah 2:2)
- غَفُورٌ لَّطِيفٌ (Surah Ash-Shura 42:19)
Application:
- The Tanween sound disappears
- Laam is pronounced with emphasis, no nasal sound
4. Idgham of Tanween into Raa (ر) with Examples
When Tanween is followed by Raa (ر), it merges directly into Raa without ghunnah.
Examples from the Quran:
- غَفُورٌ رَّحِيمٌ (Surah Al-Baqarah 2:173)
- سَمِيعٌ رَّحِيمٌ (Surah Al-Baqarah 2:127)
Quick understanding:
- Tanween is absorbed into Raa
- No ghunnah is applied at all
Special Case of Idgham (Incomplete / Exception Cases)
There are specific situations where Idgham does not occur, even though the letters of Idgham appear. This happens when Noon Saakin comes within the same word, not between two words. In such cases, the rule changes to Izhar (clear pronunciation) instead of Idgham.
Common Quranic examples:
- دُنْيَا (Surah Al-Baqarah 2:85)
- بُنْيَانٌ (Surah As-Saff 61:4)
- قِنْوَانٌ (Surah Al-An’am 6:99)
- صِنْوَانٌ (Surah Ar-Ra’d 13:4)
Why this happens:
- Idgham requires two separate words
- When letters come in the same word, merging would distort pronunciation
Final Words
Mastering the types of Idgham in Tajweed builds a strong foundation for smooth and accurate Quran recitation. Each type, with or without ghunnah, plays a key role in preserving proper pronunciation and meaning.
Consistent practice with real Quran examples helps you recognize these patterns naturally during reading and memorization. To strengthen your Hifz course journey and apply Tajweed rules correctly, explore structured learning with Quran Sheikh and take your recitation to the next level.
