Sifat Al-Huruf: Letter Characteristics Every Student Should Know

Sifat al-huroof are the characteristics of the Arabic letters: the way each letter is pronounced once you know where it comes from. The makhraj tells you the place; the sifat tell you the manner, such as whether breath flows or stops, whether the tongue rises or stays low, and whether the sound bounces or whistles. Ibn al-Jazari, whose poem most tajweed teachers follow, lists 17 characteristics: five pairs of opposites and seven single qualities. Students who learn Tajweed online with us study them right after the articulation points, because they are what keep similar letters apart.

This guide explains every sifah in plain English, gives the classical memory phrase for each group of letters, and shows how the qualities work together in the letters people confuse most.

Why Sifat Matter

Several letters share the same articulation point. Ta (ت), dal (د) and the heavy ta (ط) all come from the tip of the tongue against the roots of the upper front teeth. If you only knew the makhraj, you would pronounce them identically. Their sifat are what make them three different letters, and three different meanings.

Imam Ibn al-Jazari defined tajweed as giving every letter its due. Classical teachers explain this as two layers: the permanent qualities each letter always carries (its haqq), and the changes it takes from its position, such as heaviness or ghunnah (its mustahaqq). The sifat in this article are the first layer, and they never switch off. If you have not yet studied the articulation points, start with our guide to makharij al-huroof.

The Five Pairs of Opposite Characteristics

Each letter takes exactly one side of every pair. For strength of sound, a letter is either shiddah, rakhawah, or in between.

All letters not listed in a phrase take the opposite quality. So every letter outside فَحَثَّهُ شَخْصٌ سَكَتْ has jahr, every letter outside the isti’la group has istifal, and so on.

Hams and Jahr

With hams, a little breath escapes because the letter rests lightly on its makhraj. Stop on كَيْفَ as كَيْفْ, or say the sakin س in يَسْتَطِيعُ, and you will feel a little air escape. With jahr, the breath is held back, giving a fuller, voiced sound.

Shiddah, Rakhawah and Tawassut

With shiddah, the sound is locked completely for a moment, as in the ب or د with sukoon. With rakhawah, the sound continues, as in س or ش. The five tawassut letters sit between the two: the sound neither stops sharply nor flows freely. Note that ت and ك have both hams and shiddah: the sound stops, then a small puff of breath follows.

Isti’la and Itbaq

Isti’la lifts the back of the tongue toward the roof of the mouth, which makes the letter heavy (tafkheem). Itbaq goes further: the middle of the tongue presses up and encloses the sound. That is why the four itbaq letters, ص ض ط ظ, are the heaviest of all. How heavy they sound also depends on the vowel they carry, a topic covered under tafkheem and tarqeeq.

Idhlaq and Ismat

The six idhlaq letters flow easily from the tip of the tongue or the lips. Classical linguists also noted that a native Arabic root of four or five letters almost always contains at least one of them. The remaining letters carry ismat. This pair matters more for language than for recitation, but it completes the count.

Tap the letter groups in the explorer below to see where each one is made, then match it with its qualities from the table above.

The Seven Characteristics Without Opposites

These qualities belong to only a few letters each, and they are often what gives a letter its unique sound.

1. Safir (whistling): ص ز س. A sharp, whistle-like sound as air passes the tongue tip.
2. Qalqalah (echoing): ق ط ب ج د, remembered as قُطْبُ جَدٍّ. The letter bounces when it carries sukoon. See our full guide to qalqalah in tajweed.
3. Leen (softness): و and ي when they have sukoon and the letter before has a fatha, as in خَوْف and بَيْت.
4. Inhiraf (deviation): ل and ر. The sound inclines away from its starting point toward the sides or the back of the tongue.
5. Takrir (repetition): ر. The tongue tends to trill. You learn this quality to control it: the ra should not roll repeatedly.
6. Tafashshi (spreading): ش. The air spreads through the mouth.
7. Istitalah (extension): ض. The sound stretches along the side edge of the tongue from back to front.

Sifat in Action: Telling Similar Letters Apart

Here is how the qualities separate letters that beginners often merge.

Teachers often point to ط as the strongest letter, because it gathers jahr, shiddah, isti’la, itbaq and qalqalah. Letters such as ه, with hams, rakhawah, istifal and infitah, sit at the gentle end. For extra drills on the hardest sounds, see ways to pronounce difficult Arabic letters.

Common Mistakes With Sifat

• Losing the hams of ت and ك when they carry sukoon, so the word sounds swallowed. A light breath should follow.
• Adding qalqalah to the wrong letters, such as bouncing a sakin ك or ت. Only قُطْبُ جَدٍّ echo.
• Over-rolling the ra. Takrir is a quality to restrain, not to show off.
• Making the heavy letters light, especially ص and ط in words like الصِّرَاط.
• Turning ض into a د or ظ sound, which loses its istitalah.

Small qualities like these are hard to hear in your own voice. Live correction in our Tajweed rules course is usually the fastest way to fix them. You will also meet these qualities when reciting the disconnected letters at the start of surahs; see how to recite the huruf muqatta’at.

Frequently Asked Questions

How many sifat al-huroof are there?

Following Ibn al-Jazari, most teachers count 17: ten in five opposite pairs and seven without opposites. Some scholars count differently, for example by adding ghunnah, but the 17 in his poem are the standard list taught today.

What is the difference between makharij and sifat?

Makharij are the places where letters are produced, such as the throat or the lips. Sifat are the qualities of how they are produced, such as breathiness or heaviness. Two letters can share a makhraj and still differ completely in their sifat.

Do I need to memorize all the sifat?

To recite correctly, you need to pronounce them correctly, which a teacher can train by ear. Memorizing the names and letter groups becomes important if you study tajweed theory, sit a tajweed exam or plan to teach.

Which letter has the most characteristics?

The ra (ر) carries seven: jahr, tawassut, istifal, infitah, idhlaq, inhiraf and takrir. The ط is often called the strongest letter because most of its qualities are strong ones.

Can I learn sifat online?

Yes. A teacher can hear your pronunciation over a live call and correct breath, heaviness and bounce as you recite. Our online Tajweed classes are one-to-one, so every letter gets attention.
