1. Izhar Halqi — Clear Pronunciation
If Noon Sakinah or Tanween is followed by one of the six throat letters ء ه ع ح غ خ, pronounce the Noon sound clearly from the tongue tip without merging it into the next letter.
مِنْ هَادٍ · عَلِيمٌ حَكِيمٌ
Keep the sound clean. Do not hide it or add an unnecessarily long Ghunnah.
2. Idgham — Merging
When followed by ي ر م ل و ن, remembered as يَرْمَلُون, the Noon or Tanween merges into the next letter. Idgham with Ghunnah uses ي ن م و; Idgham without Ghunnah uses ل ر.
مَنْ يَعْمَلْ · مِنْ رَبِّهِمْ
Do not keep an independent Noon after merging. For Laam and Raa, remove the nasal hold required by the Ghunnah group.
3. Iqlab — Conversion Before Baa
Before ب, Noon Sakinah or Tanween changes to a concealed Meem sound with Ghunnah for two counts. The lips prepare gently for Baa without making a fully separate Meem syllable.
مِنْ بَعْدِ · سَمِيعٌ بَصِيرٌ
Many Mushafs mark Iqlab with a small Meem. Keep the nasal sound hidden and balanced.
4. Ikhfa Haqiqi — Concealment
Before the remaining fifteen letters ت ث ج د ذ ز س ش ص ض ط ظ ف ق ك, conceal the Noon or Tanween between clear pronunciation and complete merging, with Ghunnah for two counts.
مِنْ شَرِّ · أَنْفُسَكُمْ
The tongue should not close fully on the Noon’s normal articulation. Prepare for the following letter while maintaining nasal resonance.
