Understanding Idgham (Merging): With Ghunnah (YANMU) and Without Ghunnah
Qari Muhammad Bilal
Senior Tajweed Tutor • Published by Rahma Quran Academy
Idgham means "to merge or assimilate". When Noon Sakinah or Tanween meets one of the six letters of Yarmaloon (ي, ر, م, ل, و, ن), the Noon vanishes completely into the following letter.
فَمَن يَعْمَلْ مِثْقَالَ ذَرَّةٍ خَيْرًا يَرَهُ
“So whoever does an atom’s weight of good will see it.” (Surah Az-Zalzalah 99:7)
Comprehensive Guidelines & Key Takeaways
1. Idgham with Ghunnah (ي, ن, م, و)
The four letters of YANMU. The Noon is merged while maintaining a rich 2-count nasal resonance (e.g., مَن يَقُولُ becomes "May-yaqool").
2. Idgham without Ghunnah (ر, ل)
The letters Raa and Lam. Complete merging with zero nasal sound (e.g., مِن رَّبِّهِمْ becomes "Mir-rabbihim").
3. The Single-Word Exception
Idgham ONLY occurs across two separate words. If Noon Sakinah and a YANMU letter appear in the same word (دُنْيَا, بُنْيَانٌ, قِنْوَانٌ, صِنْوَانٌ), Izhar Mutlaq must be applied.
Teacher’s Expert Advice
Listen carefully to ensure you do not add Ghunnah when merging into Lam and Raa; the transition must be crisp and clean.
