Idgham without Ghunnah occurs before only two letters:
Lam (ل) and Ra (ر)
When Nun Sakinah or Tanween meets these letters, the noon merges
without any ghunnah (no nasal sound).
Examples:
- "مِن لَّدُنْهُ" → noon merges into Lam without ghunnah
- "مِن رَّبِّهِم" → noon merges into Ra without ghunnah
- "غَفُورٌ رَّحِيمٌ" → tanween merges into Ra
Reason: Lam and Ra are articulated close to Noon, so it fully merges with no ghunnah retained.
Question: What is the difference between Idgham with and without Ghunnah?
Answer: Idgham with Ghunnah retains the nasal sound (2 counts) — Idgham without Ghunnah has no nasal sound. Letters: Lam and Ra
