Qalqalah: The Echoing Letters Explained

Qalqalah is the small “bounce” or echo you hear on five Arabic letters when they carry a sukoon, no vowel. Without it, these letters swallow themselves and almost disappear. With it, each one is clear. It is one of the first named tajweed rules children learn, and one of the easiest to hear once you know to listen for it.

What Qalqalah Is

The word qalqalah (قلقلة) means shaking or disturbance. The five letters it applies to are gathered in the phrase قُطْبُ جَدٍّ (qutbu jadd):

ق   ط   ب   ج   د

These letters are strong: the airflow is fully stopped when they are pronounced. When one of them has a sukoon, that full stop would make it nearly silent, so the reciter releases it with a short bounce. The bounce is not a vowel. It is a quick release, closer to an echo than to an extra “a” or “u” sound.

The Levels: Minor and Major

Minor qalqalah (sughra)

When a qalqalah letter has a sukoon in the middle of a word, or at the end of a word you are not stopping on, the bounce is light. A common example is in Surah Al-Kawthar (108:3):

إِنَّ شَانِئَكَ هُوَ ٱلْأَبْتَرُ

The ب in al-abtar has a sukoon mid-word, so it gets a light bounce.

Major qalqalah (kubra)

When you stop on a word ending in a qalqalah letter, the letter becomes sakin because of the stop, and the bounce is stronger. Surah Al-Ikhlas is full of examples: stopping on ahad, as-samad, yalid, yulad and ahad again, all ending in د.

قُلْ هُوَ ٱللَّهُ أَحَدْ

The opening of Surah Al-Falaq ends the same way: stopping on al-falaq gives a clear qalqalah on the ق.

Some teachers describe a third, strongest level when you stop on a qalqalah letter that also has a shaddah, as at the end of Surah Al-Masad’s first verse. Others treat it as part of the major level. Your child’s teacher will follow the way they were taught; both describe the same sound.

How It Should Sound

• Short. A bounce, not a separate syllable. “Ahad-uh” is a mistake.
• Not a vowel. The sound should not lean clearly towards a, i or u.
• Matched to the letter. Heavy letters (ق and ط) keep their heavy quality in the bounce; ب, ج and د stay light.
• Stronger at a stop than in the middle of a word.

Common Mistakes

• No bounce at all, so the letter is swallowed and the word sounds cut off.
• Adding a vowel, turning ahad into “ahada” or “ahadu”.
• Bouncing letters that aren’t in the group, such as ك or ت, which many English speakers do by habit.
• Over-doing it in the middle of words, where it should be light.

These are among the mistakes teachers correct most often in children. Our guide to common tajweed mistakes covers the others.

How to Practise

• Start with Al-Ikhlas. Four short verses, each stop a major qalqalah on د. Most children already know it.
• Listen, then copy. Play a slow teaching recitation and pause after each verse.
• Practise the letter alone with a sukoon before putting it in words: ab, aj, ad, aq, at with a heavy ط.
• Read with a teacher. Qalqalah is easy to over- or under-do, and a few corrections fix it quickly.

Qalqalah depends on producing each letter from its correct point, so it helps to know the makharij first. For the bigger picture, see what tajweed is and why it matters.
