Lesson

1. Section Four: permanent qualities, letter by letter

After learning the names of the sound qualities, the book applies them to individual letters in Section Four. The point is to identify not merely the articulation point but the particular qualities accompanying each letter.
The printed chart has 29 entries. We shall read them in manageable groups, maintaining the book’s order. Remember that a written description is a guide for guided listening and recitation, not a substitute for hearing the correct sound.

2. How to read the qualities chart

The recurring labels group sound qualities by breath (jahr/hams), obstruction or flow (shiddah/tawassuṭ/rikhāwah), tongue height (istiʿlāʾ/istifāl) and contact (iṭbāq/infitāḥ). Some letters also have special properties such as qalqalah, ṣafīr, tafashshī, takrīr, istiṭālah, ghunnah, madd or līn.
For example, both ب and ت are stops, yet one is voiced (jahr) and the other breathy (hams). Learn combinations, not just disconnected definitions.

3. Chart entries 1–4: alif, bāʾ, tāʾ, thāʾ

ا: the chart connects alif of lengthening with jahr, rikhāwah, low tongue and openness; its length and colour need careful attention. Alif is not the same as ء.
ب: jahr, shiddah, istifāl, infitāḥ, qalqalah. ت: hams, shiddah, istifāl, infitāḥ. ث: hams, rikhāwah, istifāl, infitāḥ. Compare a complete closure in tāʾ with the continuing air passage in thāʾ.

4. Chart entries 5–8: jīm, ḥāʾ, khāʾ, dāl

ج: jahr, shiddah, istifāl, infitāḥ, qalqalah; unlike shīn’s spreading fricative quality. ح: hams and rikhāwah with a low tongue and open articulation.
خ: hams, rikhāwah, istiʿlāʾ, infitāḥ; distinguish it from ḥāʾ. د: jahr, shiddah, istifāl, infitāḥ, qalqalah; distinguish it from breathy tāʾ. Slowly compare أَجْ، أَحْ، أَخْ، أَدْ.

5. Chart entries 9–12: dhāl, rāʾ, zāy, sīn

ذ: jahr, rikhāwah, istifāl, infitāḥ—without dāl’s complete stop. ر: jahr, intermediate flow, low tongue and openness; the book notes its repetition tendency and contextual heavy/light pronunciation, not an instruction to roll it repeatedly.
ز: voiced fricative with ṣafīr. س: breathy fricative with ṣafīr. Their whistle-like effect is shared, but the breath/voice contrast matters.

6. Chart entries 13–16: shīn, ṣād, ḍād, ṭāʾ

ش has hams, rikhāwah, istifāl, infitāḥ and tafashshī (spreading of sound). ص is breathy but elevated, emphatic and whistling, not simply a heavier written sīn.
ض has jahr, rikhāwah, istiʿlāʾ, iṭbāq and istiṭālah; its articulation needs special training. ط combines jahr, shiddah, istiʿlāʾ, iṭbāq and qalqalah. Do not merge any of these four distinct consonants.

7. Chart entries 17–20: ẓāʾ, ʿayn, ghayn, fāʾ

ظ: jahr, rikhāwah, istiʿlāʾ, iṭbāq and emphatic pronunciation; it must not collapse into ḍād. ع: jahr, intermediate flow, istifāl and openness, unlike breathy ḥāʾ.
غ: jahr, rikhāwah, istiʿlāʾ and openness, unlike the breathy خ. ف: hams, rikhāwah, istifāl and infitāḥ, articulated with the lower lip and upper front teeth.

8. Chart entries 21–24: qāf, kāf, lām, mīm

ق has jahr, shiddah, istiʿlāʾ, infitāḥ, qalqalah and emphatic colour; ك has hams, shiddah, istifāl and infitāḥ. Do not pronounce them as one sound.
ل is voiced with intermediate flow and typically thin; specific contexts, including the divine name, are treated in the next chapter. م is voiced and intermediate, with nasal resonance (ghunnah). The lips form the closure while the nasal passage contributes its characteristic tone.

9. Chart entries 25–29: nūn, wāw, hāʾ, hamzah, yāʾ

ن has jahr, intermediate flow, istifāl, infitāḥ and ghunnah. و has voiced and flowing qualities, with madd or līn when conditions fit. ه is breathy and flowing; it is not a glottal stop.
ء is voiced and completely stopped, unlike hāʾ. ي can display madd or līn in relevant conditions. These are the final entries of the book’s 29-letter chart.

10. Two cautions when using the chart

Each letter has a bundle of simultaneous qualities; these are not separate sounds to be stacked upon it. The book also notes phenomena whose realization depends on context: a consonant’s vowel or sukūn, the preceding sound, and the position in a word.
For instance, qalqalah is tested particularly in an unvowelled member of its group; a moving ب does not receive an invented extra bounce. Likewise not every occurrence of wāw or yāʾ is a lengthening letter.

11. Section Five: distinguishing qualities

The next heading is Ṣifāt Mumayyizah—qualities by which similar letters are differentiated. The author’s method is comparative: similar inherent qualities may require a difference of articulation point; a shared or close point may require a difference in the manner of articulation.
This section does not introduce a new list of temporary qualities; it explains which properties help keep particular letters distinct.

12. How alif, hamzah and hāʾ differ

The author starts with alif, hamzah and hāʾ. Alif of madd is characterized by extension. Hamzah combines jahr and shiddah, while hāʾ is hams with rikhāwah.
Listen to ءَ (distinct onset), هَ (breathy flow) and the lengthening alif in قَالَ. Their similarity as written symbols or nearby phonation must not erase their different identities.

13. ʿAyn versus ḥāʾ

Both ع and ح are pharyngeal/throat consonants. The book differentiates ʿayn by jahr and intermediate flow, versus ḥāʾ by hams and free flow.
Read عَ، حَ slowly and separately. Merely making ḥāʾ louder will not turn it into ʿayn; their articulations and acoustic qualities need to remain distinct.

14. Ghayn versus khāʾ: voicing and breath

غ and خ share an elevated-tongue fricative character, but the book contrasts ghayn’s jahr with khāʾ’s hams.
Compare غَيْر and خَيْر. The goal is controlled voicing and breath, not excessive pressure on the throat. Their consonant difference can change a word’s meaning.

15. Jīm, shīn and yāʾ

The text compares ج، ش، ي among letters requiring careful distinction. Jīm has jahr and shiddah and can exhibit qalqalah when sākin. Shīn is breathy, flowing and spread (tafashshī). Yāʾ differs in its sound and may function as madd or līn in suitable patterns.
Practice أَجْ، أَشْ، أَيْ without collapsing the consonants into the same gentle sound.

16. Ṭāʾ, dāl and tāʾ: shared closure, different character

All three—ط، د، ت—share shiddah, a firm closure. But ṭāʾ combines jahr, raised tongue and iṭbāq; dāl is voiced but low and open; tāʾ is breathy, low and open.
Read طَ، دَ، تَ without confusing them. A common property (complete closure) never cancels other properties that define separate letters.

17. Ẓāʾ, dhāl and thāʾ

ظ، ذ، ث all allow continuing airflow at closely related dental articulations. Yet ẓāʾ is voiced, raised and emphatic; dhāl is voiced, low and open; thāʾ is breathy, low and open.
Practice ظَ، ذَ، ثَ. The book uses such sets to show that shared rikhāwah does not make the consonants interchangeable.

18. Ṣād, zāy and sīn: three whistling letters

ص، ز، س share ṣafīr, a sibilant/whistling effect. Ṣād is breathy but elevated and emphatic; zāy is voiced, low and open; sīn is breathy, low and open.
Read صَ، زَ، سَ and listen for what remains shared and what differs. The common hiss is not permission to flatten the three sounds into one.

19. Lām, nūn and rāʾ: beyond their shared middle quality

ل، ن، ر share voiced and intermediate-flow qualities, with a low tongue and open configuration. Yet their articulation and special features differ: nūn has ghunnah, rāʾ has a tendency toward takrīr, and lām has its own lateral articulation.
Practice لَ، نَ، رَ while retaining each consonant’s identity; do not exaggerate the trill of rāʾ.

20. Wāw, bāʾ and mīm: a shared lip region

و، ب، م all involve the lips, but their manner is distinct. Bāʾ is a stop and can have qalqalah when unvowelled; mīm is intermediate with nasal resonance; wāw flows and can function as madd or līn in the relevant contexts.
Practice بَ، مَ، وَ. Shared geography of articulation does not mean shared sound.

21. Ḍād and ẓāʾ: the source’s extended note

The marginal note spends considerable space on ض and ظ. They share jahr, rikhāwah, istiʿlāʾ and iṭbāq but differ in articulation point: ḍād is associated with the side of the tongue and the molars; ẓāʾ with the front of the tongue and upper teeth.
The book also attributes istiṭālah to ḍād and discusses recitational observations about their pronunciation. The pedagogical conclusion is to preserve two distinct letters rather than letting one replace the other.

22. Training ḍād and ẓāʾ without overcompensation

The long note mentions different scholarly ways of describing these closely related emphatic consonants. It should not be simplified into “ḍād is just dāl” or “ẓāʾ and ḍād may be merged”.
Hear and repeat ضَ، ظَ with a competent teacher. A diagram or mirror may help with gross tongue position, but trained listening and feedback are needed to check the sound.

23. Integrated differentiation practice

Review the comparison sets from this section: ء/ه، ع/ح، غ/خ، ط/د/ت، ظ/ذ/ث، ص/ز/س، ل/ن/ر، و/ب/م، ض/ظ. For each set, name one shared characteristic, one distinguishing feature, and then produce the sounds separately.
For example, zāy and sīn share ṣafīr and rikhāwah, but differ in jahr versus hams. Ṭāʾ and tāʾ share closure but differ in elevation and emphatic contact.

24. Takeaway: inherent versus distinguishing qualities

Section Four listed the inherent qualities of the 29 letters. Section Five demonstrated how one feature—breath, closure, tongue position, emphatic contact, or articulation point—can distinguish otherwise similar consonants.
A shared ṣifah does not erase a letter’s identity. As a personal check, identify one common and one differentiating quality for each comparison set, then test your pronunciation by hearing an accurate recitation. The next chapter begins the separate rules of tafkhīm and tarqīq.
