There are five qalqalah letters in Arabic: ق ط ب ج د — Qaf, Ta, Ba, Jeem and Dal — gathered in the mnemonic قطب جد (Qutbu Jad). When one of them carries a sukoon, it is released with a light bounce or echo instead of being pressed flat. That bounce is qalqalah, and this page gives you the letters, the two types, real Quranic examples with the recitation of Sheikh Al-Husary, and a free game to practise spotting them.

What Are the Qalqalah Letters?

The word qalqalah (قلقلة) literally means shaking, disturbance or vibration. In Tajweed it describes a very short, controlled movement of sound that escapes when one of the five letters is released. You will also see the rule written as qalqala, qolqolah or haroof e qalqalah in different transliterations — they all refer to the same rule and the same five letters.

The reason this rule exists is phonetic rather than decorative. These five letters share one key feature: they are all shadidah (plosive) — the airflow is completely blocked at the point of articulation. Without the bounce, the blocked air simply has nowhere to go and the letter can sound muted or swallowed, so it is harder for the listener to hear clearly. The qalqalah releases that blockage cleanly, so the letter stays audible.

This is why qalqalah is worth getting right. A reciter who skips it is not simply reciting in a plainer style: omitting qalqalah affects the correct articulation of the letter and may make it less clear, but it does not necessarily mean that the letter itself has been omitted. Every recognised chain of recitation applies the rule, which is one of the reasons it is usually among the first three or four rules taught to a beginner alongside the other core Tajweed rules.

The 5 Qalqalah Letters and Their Makhraj

Each of the letters of qalqalah has its own point of articulation (makhraj). Knowing where the letter is formed makes the bounce far easier to produce, because the bounce is simply the release of that exact point:

The mnemonic: قطب جد

Rather than memorising five separate letters, teachers gather them into one short phrase: قطب جد, read as Qutbu Jad. Every letter in that phrase is a qalqalah letter, in order: ق, ط, ب, then ج, د. Learn the phrase and the whole list comes with it — which is why almost every child taught in a traditional halaqah can recite the huruf qalqalah before they can explain the rule.

Some books use the variant qutb jadd or write it as two words. The spelling makes no difference; the five letters are fixed and agreed upon.

How Many Qalqalah Letters Are There?

Learners often expect the list to be longer, and there are two usual reasons. The first is confusion with the heavy letters of tafkheem — ص, ض, ط, ظ, غ, خ, ق. Two letters (ط and ق) belong to both groups, so students who meet tafkheem first assume the rest of that group bounces too. It does not: ص and ض are pronounced heavy, but the air is not released with an echo.

The second reason is that a qalqalah letter with a vowel on it does not bounce, so learners hear ب in bismi and conclude the rule is inconsistent. It is not — the rule only ever activates on sukoon. That single condition is what separates a qalqalah letter from an actual qalqalah occurrence.

How to Pronounce Qalqalah Letters (Step by Step)

The mechanic is the same for all five letters. Only the point of contact changes:

Listen and Practice: Qalqalah Letters in Action

Reading about qalqalah isn’t the same as hearing it. Below, tap each letter to hear a real Quranic word where that letter carries a sukoon, recited by Sheikh Mahmoud Khalil Al-Husary, so you can hear exactly what the bounce sounds like — then repeat it aloud yourself before moving to the next one.

The Two Types of Qalqalah: Sughra vs Kubra

The rules of qalqalah divide it into two levels of strength. The letters are identical in both; what changes is whether you read on past the sakin letter or stop on it, and therefore how much the bounce is emphasised.

The last row of that table catches a lot of learners. In qul huwa Allāhu aḥad, the د bounces only because you stopped on it — in the Mushaf the word is written أَحَدٌ, with tanween. When أَحَدٌ is connected to اللَّهُ الصَّمَدُ, the dāl remains vowelled, so there is no qalqalah on it. The pronounced nūn of tanween takes a kasrah to avoid two consecutive sakin letters: aḥaduni-llāhuṣ-ṣamad. The final دْ of يُولَدْ works differently: its sukoon is original, so if you join that ayah to the next one, it stays sakin and keeps a lighter qalqalah.

Examples of Qalqalah from the Quran

These five ayat are the ones most often used to teach the rule, because the bounce falls in a place you cannot miss. Press play on each, and follow the highlighted letter as Sheikh Al-Husary recites it.

Surah Al-Ikhlas and Al-Falaq are worth reciting slowly as a pair once you know the rule, because both contain several clear qalqalah examples, particularly at the stops: every ayah of each surah ends on a qalqalah letter, so the qalqalah kubra lands on the final letter of several ayat in a row. Children pick the rule up from these two surahs faster than from any explanation.

If you want to hear the same reciter across a longer passage while you practise, the phrase-by-phrase player on our Ayat al-Kursi memorization tool and on the last two ayat of Al-Baqarah uses the same recitation.

Common Mistakes Students Make with Qalqalah

Practise: Pop the Qalqalah Letters (Free Game)

Recognising the letters in isolation is easy; recognising them inside a running word is the actual skill. Play the game below — pop only the letters of qalqalah as they appear, and try to finish without popping a wrong letter. It works on phones and tablets, and no account is needed.

Why Qalqalah Matters in Quran Recitation

Tajweed exists to preserve the Quran as it was recited and taught, sound for sound, through an unbroken chain of transmission. Qalqalah is a small part of that, but it is a part that is heard on almost every page — the five letters are among the most common in the language, and a reciter who ignores the rule alters the shape of hundreds of words.

It is also a rule with a genuine payoff for beginners. Unlike the finer points of madd, qalqalah can be learned in an afternoon and applied immediately, and it makes recitation sound noticeably more correct straight away. That early win is often what carries a student into the rest of the Tajweed rules course.

You can learn the five letters from this page and drill them in the game above, but qalqalah is a sound, and a sound needs an ear on the other side. A teacher listening to you for ten minutes will tell you immediately whether your bounce is too heavy, too light, or landing on the wrong letter — something no page or app can do for you.

May Allah beautify your recitation and accept it from you. 🤲
