Basic Noon Saakinah Rules

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.
