The Larynx/Throat Articulation Points — The Six Pharyngeal Letters

Definition:
The throat (halq) is the passage extending between the larynx and the mouth. It has three subdivisions, each producing two of the six pharyngeal letters.

Three Sub-points of the Throat:

1. Deepest throat (closest to chest): Hamza (ء) and Haa (هـ).
2. Middle throat: 'Ain (ع) and Haa (ح).
3. Upper throat (nearest to mouth): Ghain (غ) and Khaa (خ).

Characteristics of Pharyngeal Letters:

• They trigger clear throat display (Izhhaar Halqi) of sukoon noon and tanween.
• Idghaam, Ikhfaa, and Iqlaab are all impermissible before these letters.
• Hamza and Haa are furthest from the mouth (deepest throat).
• Ghain and Khaa are nearest the mouth and are both heavy (Isti'la) letters.

Rule:
Sukoon noon or tanween before any of the six pharyngeal letters = Izhhaar Halqi (clear articulation, no ghunna with the following letter).

Examples:
• "Min 'ilmin" — sukoon noon before 'Ain: clear throat izhhaar.
• "An Hakeemun" — sukoon noon before Haa: clear throat izhhaar.
• "Khayrun amma" — tanween before Hamza: clear throat izhhaar.
