The letters of Qalqalah are ق ط ب ج د — Qaf, Ta, Ba, Jeem and Dal. They produce a short, controlled bounce when they carry a sukoon or when you stop on them.
The qalqalah letters (also called the letters of Qalqalah) are Qaf (ق), Ta (ط), Ba (ب), Jeem (ج) and Dal (د). Each one bounces when it carries a sukoon.
Qalqalah (قَلْقَلَة) literally means "shaking" or "disturbance." In Tajweed, it refers to a slight echo or bounce sound that occurs on specific letters when they carry a sukoon (no vowel) — either within a word or when stopping at the end.
Think of it as the sound of a letter releasing rather than stopping dead. It's a brief, controlled vibration — not a full vowel, not silence. Something in between.
There are exactly five letters that carry Qalqalah. A common memory aid that gathers them together is قُطْبُ جَدٍّ (Qutbu Jadd). The table below gives each letter with its sound location and a Quran example:
These letters produce Qalqalah only when they have a sukoon — either marked or implied when stopping (waqf).
| Letter | Name | Sound location | Quran example |
|---|---|---|---|
| ق | Qaf | Back of the tongue | الْفَلَقْ |
| ط | Ta | Tip of the tongue | أَطْعَمَهُم |
| ب | Ba | Lips | أَبْتَرُ |
| ج | Jeem | Middle of the tongue | يَجْعَلُونَ |
| د | Dal | Tip of the tongue | أَحَدْ |
The letter stops briefly, then a slight resonance or echo is released — like a gentle tap on a drum.
The echo is not a vowel — don't add "a", "i", or "u". It's purely a release of the stopped sound.
Qalqalah is most prominent when you stop (waqf) on one of these letters at the end of an ayah.
The word أَحَدْ — from Surah Al-Ikhlas — ends with a دال (Dal) at sukoon when stopping. Release a slight echo on the Dal rather than ending it in silence.
Similarly, الْفَلَقْ ends with Qaf when stopping. Qaf is articulated by raising the back of the tongue toward the soft-palate area, then releasing the stopped sound with a controlled bounce.
Mid-word examples include أَطْعَمَهُم, أَبْتَرُ and يَجْعَلُونَ. In each one, keep the bounce brief so it does not turn into an extra vowel.
The most common mistake. The letter simply stops with no resonance, making the recitation sound abrupt.
Over-doing Qalqalah sounds unnatural and breaks the flow. The echo should be subtle and controlled.
Some reciters add "ah" or "a" after the letter — this is incorrect Tajweed and alters the word.
Step 1: Say each letter with sukoon: أَقْ، أَطْ، أَبْ، أَجْ، أَدْ. Step 2: Keep the letter closed briefly, then release it without adding “a”, “i” or “u”. Step 3: Practise the Quran examples above, first slowly and then within the full ayah.
The qalqalah letters are ق ط ب ج د: Qaf, Ta, Ba, Jeem and Dal. Each one produces a short bounce when it carries a sukoon.
The letters of Qalqalah are the same five letters, ق ط ب ج د. The mnemonic قُطْبُ جَدٍّ (Qutbu Jadd) gathers them in one phrase.
Qalqalah (قَلْقَلَة) means “shaking” or “disturbance”. It is the slight echo or bounce heard on the five qalqalah letters when they carry a sukoon.
Qalqalah occurs when one of the qalqalah letters carries a sukoon, either within a word or because you stop on that letter at the end of a word.
Sughra is the lighter bounce on a sakin qalqalah letter within a word. Kubra is the stronger, clearer bounce heard when stopping on a qalqalah letter.
No. The bounce must not become “a”, “i” or “u”. It is a controlled release of the stopped consonant.
Yes. A qalqalah letter with a sukoon bounces whether you continue or stop. When you continue the bounce is usually lighter, and when you stop on the letter it becomes clearer.
Say أَقْ، أَطْ، أَبْ، أَجْ، أَدْ slowly, release each letter without a vowel, then apply the same bounce to a few Quran examples. Record yourself and compare, or use the QariAI tajweed checker for feedback.
Qalqalah has levels of strength. Teachers name them slightly differently, so follow your own teacher's terms, but the idea is the same everywhere: the bounce grows as the letter becomes more final.
| Level | When it happens | Strength | Example |
|---|---|---|---|
| Sughra (minor) | The letter has a sukoon in the middle of a word | Light | يَجْعَلُونَ |
| Kubra (major) | You stop on the letter at the end of a word or ayah | Clear | أَحَدْ |
| Strongest | You stop on a qalqalah letter that carries a shaddah | Fullest | الْحَقّ |
Mid-word, the echo is present but brief. Think of a soft tap, then move straight on.
When you stop, there is no following sound to cover the letter, so the bounce is easier to hear. Give it a clear release without turning it into a vowel.
A doubled letter at a stop needs the fullest, most deliberate release. This is where reciters most often under-do it.
Qalqalah sits inside the wider set of tajweed rules. If you are new to them, the beginner tajweed curriculum shows where qalqalah fits in a sensible learning order. Because each qalqalah letter has its own articulation point, the makharij chart helps you place Qaf, Ta, Ba, Jeem and Dal correctly. Once the rule is comfortable, use the free tajweed mistakes checker to hear what a flat or over-done bounce sounds like, and the hifz revision planner to build qalqalah practice into your daily review. If you also want to work on melody once your tajweed is solid, see our guide to the maqamat in Quran recitation.
Most people don't realise they're missing Qalqalah until someone tells them. Our free checker detects missing or over-done Qalqalah in your recitation and shows you exactly what to adjust.
