Sifaat Al Huroof in Tajweed

Key Takeaways

Sifaat al huroof are the inherent characteristics of each Arabic letter, distinguishing letters that share identical articulation points (makharij).

There are 17 essential sifaat (attributes), divided into paired opposites (10 attributes) and attributes with no opposite (7 attributes).

Every Arabic letter carries a minimum of 5 sifaat and a maximum of 7, determined by both paired and unpaired characteristics.

Strong sifaat (like Jahr, Shiddah, Isti’la) produce heavier, fuller sounds; weak sifaat produce lighter, flowing sounds affecting Tafkhim and Tarqiq.

Recite الضَّالِّينَ (adh-dhaalleen) and الذَّاكِرِينَ (adh-dhaakireen) aloud. Both letters — Dhad (ض) and Dhal (ذ) — emerge from areas near the tongue’s edge, yet they sound nothing alike. What separates them is not where they originate, but how they behave. That behavioral fingerprint is precisely what sifaat al huroof defines.

Sifaat al huroof in Tajweed are the essential characteristics that describe how each Arabic letter is produced — covering qualities like breath flow, vocal resonance, tongue elevation, and sound pressure. 

What Is Sifaat in Tajweed?

Sifaat in Tajweed refers to the intrinsic qualities assigned to each Arabic letter at the moment of pronunciation, qualities that remain permanently attached to the letter regardless of its position in a word. 

According to classical Tajweed scholarship, these attributes serve three core functions: they distinguish letters sharing the same makhraj, they define the strength or weakness of each letter’s sound, and they govern advanced rules such as Idgham, Isti’la (heaviness), and Tarqiq (lightness).

In our experience teaching the Tajweed for Beginners course at Buruj Academy, the most persistent error among adult beginners is conflating Tha (ث), Dhal (ذ), and Dhaa (ظ) — three letters emerging from the tongue tip and upper front teeth. 

No amount of makhraj drilling alone resolves this confusion. 

Only when students internalize that Tha carries Hams (breathiness) and Isti’fal (lowness) while Dhaa carries Jahr (resonance) and Isti’la (elevation) and Itbaq (sealing) does the distinction click permanently.

Understanding sifaat is equally essential for applying Tajweed rules for beginners correctly, since rules like Ikhfa, Idgham, and Qalqalah are directly linked to the sifaat of the letters involved.

What Is the Importance of Sifaat Al Huroof in Tajweed?

Sifaat al huroof are essential for three reasons: they distinguish letters sharing the same makhraj (like Tha, Dhal, and Dhaa), they determine letter strength which governs Idgham and assimilation rules, and they ensure every letter receives its full phonetic right — a condition classical scholars considered obligatory for valid Quranic recitation.

How Many Sifaat Are There in Tajweed?

There are 17 established Sifaat Lazimah in mainstream Tajweed scholarship based on the recitation of Hafs ‘an ‘Asim. 

Scholars have minor disagreements on the precise count — some list 18 or 19 by including Khafa (faintness) and Ghunnah (nasality) as separate permanent attributes — but the standard accepted count taught and followed by the majority of Tajweed scholars is 17.

These 17 divide as follows:

Category	Sifaat Included	Count
Paired opposites (each letter takes one from each pair)	Hams/Jahr, Shiddah/Rakhawa (+ Tawassut), Isti’la/Istifal, Itbaq/Infitah, Idhlag/Ismat	10
Attributes with no opposite	Qalqalah, Safir, Inhiraf, Tafasshi, Istitalah, Takrir, Lin	7

Every letter carries a minimum of 5 sifaat (one from each opposing pair) and a maximum of 7 (when it also possesses attributes from the unpaired group).

What Is the Difference Between Makharij and Sifaat?

Makharij and sifaat are two complementary sciences that together define a letter’s full identity. Makharij refers to the precise physical location where a letter originates in the vocal tract — throat, tongue, lips, or nasal passage. Sifaat, by contrast, describes what happens to the airflow, the vocal cords, and the oral cavity during the letter’s production at that point of exit.

Think of it this way: makharij tells you where a letter is born; sifaat tells you how it lives.

Feature	Makharij	Sifaat
Definition	Physical exit point of the letter	Characteristic qualities during production
Primary Function	Locating the letter	Distinguishing and coloring the letter
Number	17 articulation points	17 essential attributes
Permanence	Fixed to the letter	Inherent (Lazimah) or situational (Aridah)
Example	ك and ق both exit from the back tongue	ك is Makhfut (light); ق carries Isti’la (heavy)

A reciter who knows only makharij will pronounce letters from the right place but may still mispronounce their quality. Mastering both together is what makes recitation authentically correct.

What Are the Primary Two Categories of Sifaat Al Huroof?

Sifaat al huroof divide into two fundamental types based on permanence. Sifaat Lazimah (essential/inherent attributes) are inseparable from the letter under all circumstances — they exist whether the letter is voweled, sukoon, or in any position. Sifaat Aridah (incidental attributes) are secondary qualities that appear only in specific recitation contexts and do not alter the letter’s core identity.

1. Sifaat Lazimah

The permanent characteristics known as Sifaat Lazimah (essential or inherent attributes) are an integral part of a letter’s identity. These qualities remain present regardless of the letter’s state—whether it carries a vowel, has a sukoon, or occupies any specific position within a word 

2. Sifaat Aridah

Sifaat Aridah include qualities like Tafkhim (heaviness applied contextually to Ra and Lam), Tarqiq, Madd (elongation), Idgham, and Ikhfa. These are studied as separate Tajweed chapters because they depend on surrounding letters and recitation context.

This distinction matters practically: when a student asks “is Ra always heavy?”, the answer requires understanding that Ra’s heaviness is Aridah — it shifts based on voweling, adjacent letters, and waqf position. 

Our Online Tajweed Classes address exactly these nuanced interactions, building from Lazimah attributes before introducing Aridah applications.

What Are The Paired Sifaat in Tajweed?

Paired sifaat are the backbone of letter classification. Every Arabic letter must carry exactly one from each opposing pair — there is no middle ground except in the specific case of Tawassut (between Shiddah and Rakhawa).

1. Hams and Jahr

Hams (الهَمْس) means the breath continues to flow during the letter’s production, indicating partial relaxation of the vocal cords. Jahr (الجَهْر) means the breath is held back, with the vocal cords fully engaged and resonating.

Letters of Hams (10 letters): collected in the phrase حَثَّهُ شَخْصٌ فَسَكَتَ — ح، ث، هـ، ش، خ، ص، ف، س، ك، ت

Letters of Jahr: all remaining 18 letters.

Attribute	Description	Example Letters	Quranic Example
Hams	Breath flows; cords relax	ف، س، ح، ش، هـ، ك، ث، ص، خ، ت	سَكَتَ
Jahr	Breath withheld; cords resonate	ب، ج، د، ذ، ر، ز، ع، غ، ق، ل…	جَعَلَ

Quranic example of Hams:

فَصَبَّ عَلَيْهِمْ رَبُّكَ 

Fasabba ‘alayhim rabbuk 

“And your Lord poured upon them…” (Al-Fajr 89:13)

Fa and Sad both carry Hams — notice the breath-like quality when these letters are pronounced correctly

2. Shiddah, Tawassut, and Rakhawa

Shiddah (الشِّدَّة) means the sound is completely blocked at the makhraj momentarily before release — producing a sharp, stopped quality. Rakhawa (الرَّخَاوَة) means the sound flows freely with no blocking. Tawassut (التَّوَسُّط) is the intermediate state between these two.

Letters of Shiddah (8): collected in أَجِدُ قَطٍّ بَكَتْ — أ، ج، د، ق، ط، ب، ك، ت

Letters of Tawassut (5): collected in لِنْ عُمَرْ — ل، ن، ع، م، ر

Letters of Rakhawa: all remaining letters.

Quranic example of Shiddah:

قَدْ أَفْلَحَ الْمُؤْمِنُونَ

Qad aflaha al-mu’minoon 

“Certainly will the believers have succeeded.” (Al-Mu’minun 23:1) 

Qaf and Dal both carry Shiddah — the sound is briefly stopped before being released

3. Isti’la and Istifal

Isti’la (الاسْتِعْلاء) means the back of the tongue rises toward the upper palate during pronunciation, producing the characteristic “heavy” or “thick” sound known as Tafkhim. Istifal (الاسْتِفَال) means the tongue remains low in the mouth, producing the lighter, “thin” sounds known as Tarqiq.

Letters of Isti’la (7): collected in خُصَّ ضَغْطٍ قِظْ — خ، ص، ض، غ، ط، ق، ظ

Letters of Istifal: all remaining 22 letters.

This sifah is the direct foundation for understanding heavy and light letters in Tajweed, and mastering it is prerequisite to correctly applying Tafkhim and Tarqiq rules throughout the Quran.

4. Itbaq and Infitah

Itbaq (الإطْبَاق) means the tongue presses against or rises very close to the upper palate, sealing the oral cavity. This produces an especially thick, enclosed sound. Infitah (الانْفِتَاح) means the tongue separates from the palate, allowing an open sound to emerge.

Letters of Itbaq (4 only): ص، ض، ط، ظ

These four letters are simultaneously Musta’liyah (elevated) and Mutbiqah (sealed) — a double-layered heaviness that makes them among the most distinct sounds in Arabic.

5. Idhlag and Ismat

Idhlag (الإذْلاق) means a letter flows easily from the tip of the tongue or the lips — producing smooth, effortless articulation. Ismat (الإصْمَات) means resistance; these letters do not flow as naturally and require deliberate effort.

Letters of Idhlag (6): collected in فِرَّ مِنْ لُبِّ — ف، ر، م، ن، ل، ب

A classical implication of Ismat is that any genuine Arabic root word of four or five letters must contain at least one Mudhlaq letter — a linguistic rule that helps distinguish authentic Arabic vocabulary from foreign borrowings.

What Are the Unpaired Sifaat in Tajweed?

Seven sifaat exist independently — a letter either possesses them or it does not. These attributes add a distinctive sonic layer beyond the five paired characteristics.

1. Qalqalah: The Echoing Bounce

Qalqalah (القَلْقَلَة) is the required echoing vibration produced when one of its five letters appears with sukoon. The sound bounces slightly after the point of contact, creating a distinctive resonance. The five letters are collected in قُطْبُ جَدٍّ — ق، ط، ب، ج، د.

Quranic example:

قُلْ هُوَ اللَّهُ أَحَدٌ 

Qul huwa Allahu ahad 

“Say, He is Allah, the One.” (Al-Ikhlas 112:1) 

Dal with sukoon at waqf produces a clear, bouncing Qalqalah.

For a full treatment of this attribute, our dedicated article on Qalqalah letters covers every rule, level, and common error in detail.

2. Safir: The Whistling Sharpness

Safir (الصَّفِير) is a sharp, whistling sound produced by three letters: ز، س، ص. The sound resembles a bird’s whistle and is produced by the air stream passing through a narrow channel between the tongue and teeth.

Letters of Safir: ز (Za), س (Seen), ص (Sad)

Quranic example of Safir:

وَالسَّمَاءِ ذَاتِ الصَّدْعِ 

Was-samaaa’i dhaatis-sad’ 

“By the sky which returns.” (At-Tariq 86:11) 

Seen and Sad in close proximity — both demonstrate Safir with their characteristic sharpness

3. Inhiraf: The Lateral Deviation

Inhiraf (الانْحِرَاف) refers to the slight lateral deflection of airflow in two letters: ل (Lam) and ر (Ra). For Lam, the air escapes from the sides of the tongue. For Ra, the tongue tip deflects slightly as sound passes around it.

4. Takrir: The Trilling Warning

Takrir (التَّكْرِير) is the natural tendency of Ra (ر) to trill — the tongue tip can vibrate and repeat rapidly. This attribute is listed as a warning, not as a desirable feature. 

A reciter must actively suppress the trill, ensuring Ra is pronounced with a single, clean contact. Exaggerating Takrir is one of the most common errors in Ra recitation.

5. Tafasshi: The Spreading Breath

Tafasshi (التَّفَشِّي) describes the wide spreading of breath across the mouth during the pronunciation of Shin (ش). The air fans out broadly across the upper palate, producing the characteristic diffuse, spreading sound that distinguishes Shin from Seen.

Quranic example of Tafasshi:

إِنَّ اللَّهَ اشْتَرَىٰ مِنَ الْمُؤْمِنِينَ 

Innallaha ashtaraa minal-mu’mineen 

“Indeed, Allah has purchased from the believers…” (At-Tawbah 9:111) 

Shin in اشْتَرَىٰ — the breath spreads visibly across the mouth

6. Istitalah: The Elongated Contact

Istitalah (الاسْتِطَالَة) is unique to Dhad (ض). During its production, the tongue’s lateral edge makes an extended contact along the upper molars — stretching from the back molars toward the front, nearly reaching the articulation zone of Lam. 

This elongated contact is what gives Dhad its distinctly complex, rich sound and is what makes it one of the most difficult letters for non-Arabic speakers to master correctly.

7. Lin: The Effortless Glide

Lin (اللِّيْن) describes the smooth, effortless glide of Waw (و) and Ya (ي) when they appear sakinah after a fath (open vowel). These letters flow without any tension or muscular effort.

Letters of Lin: Waw sakinah after Fath (وْ), Ya sakinah after Fath (يْ)

Quranic examples: بَيْت (bayt — house), خَوْف (khawf — fear), قُرَيْشٍ (Quraysh)

This sifaat al huroof chart provides a working reference for identifying each letter’s attributes — but reading a chart and internalizing the qualities through actual recitation are two very different things.

Strong, Weak, and Intermediate Sifaat in Tajweed

Understanding which sifaat are strong and which are weak directly impacts how letters interact in rules like Idgham. A letter with predominantly strong attributes resists assimilation; a letter with weak attributes blends more easily.

Strength Level	Sifaat Included
Strong	Jahr, Shiddah, Isti’la, Itbaq, Qalqalah, Safir, Inhiraf, Tafasshi
Weak	Hams, Rakhawa, Istifal, Infitah, Lin, Khafa
Intermediate	Tawassut, Idhlag, Ismat

This classification directly explains, for instance, why Idgham rules in Tajweed permit full assimilation for weaker letters like Nun into Meem, but only partial assimilation when stronger letters are involved.

How to Identify the Sifaat of Any Arabic Letter?

Identifying a letter’s full set of sifaat follows a systematic process established in classical Tajweed science. Work through the paired groups first, then check the unpaired attributes.

Step 1: Is the letter’s breath flowing or blocked? → Assign Hams or Jahr.

Step 2: Is the sound fully stopped, partially flowing, or freely flowing? → Assign Shiddah, Tawassut, or Rakhawa.

Step 3: Does the tongue rise toward the upper palate or remain low? → Assign Isti’la or Istifal.

Step 4: Does the tongue seal against the palate? → Assign Itbaq or Infitah.

Step 5: Does the letter flow easily from the tongue tip or lips? → Assign Idhlag or Ismat.

Step 6: Check the unpaired list — does the letter have Qalqalah, Safir, Inhiraf, Tafasshi, Istitalah, Takrir, or Lin?

Every letter will have exactly 5 attributes from Step 1–5, plus 0–2 from Step 6.

In our Advanced Tajweed Course at Buruj Academy, our Al-Azhar-trained instructors take students through this exact identification process for every letter, using live recitation and immediate correction rather than memorizing charts in isolation.
