Qalqalah

قلقلة

The letter that bounces

Lesson 6.1 · Module 6 · Qalqalah

Qalqalah (قلقلة): with no vowel, five letters do not stay blocked: they give a clear bounce. When qāf, ṭā, bā, jīm or dāl (ق ط ب ج د) has no vowel, or when you stop on it at the end of a word. The Quran has 3,834 of them, in 109 surahs (Hafs reading).

What does Qalqalah mean?

Qalqalah (قلقلة): the letter that bounces

A bounce produced on five letters (ق ط ب ج د) when they carry no vowel (sukun). The sound bounces from its point of articulation.

Qalqalah: the 5 letters

Qalqalah in the Quran, letter by letter: counted on the text of the Madani Mushaf.
Letter Name In the Quran
ق qāf 556
ط ṭā 154
ب bā 1,295
ج jīm 667
د dāl 1,162

How to pronounce Qalqalah

Release the letter with a small, clean bounce, without adding a vowel.

The gesture
Form the sakin letter at its normal articulation, then release it lightly once. Keep the sound brief and add no a, i or u.
Avoid
Do not turn the release into a full vowel, repeat the letter, or add a breathy sound after it.
The condition
The letter must be sakin. Qalqalah is lighter inside a word and clearer when stopping on the final letter.

Qalqalah: common mistakes

What is often heard, and how to fix it. The ▶ plays the right model, recited by al-Husary.

  1. Blocking the letter without releasing it: it bounces with a small, clear knock.

    The right model · An-Nasr 110:2

  2. Adding a vowel after the letter (“qa”, “bi”): the bounce is brief and the letter keeps its sukūn.

    The right model · Quraysh 106:4

  3. Bouncing ب ج د as heavily as ق ط: the bounce follows the letter, full for ق and ط, light for ب ج د.

    The right model · Al-'Asr 103:3

  4. Making the same bounce mid-word and at a stop: it is clearer when stopping on the letter.

    The right model · Al-Falaq 113:1

  5. Letting a breath escape after the letter: these letters hold back the breath; the bounce comes without air.

    The right model · Al-Kawthar 108:3

Qalqalah and neighbouring rules

RuleWhenWhat happens
Qalqalah When qāf, ṭā, bā, jīm or dāl (ق ط ب ج د) has no vowel, or when you stop on it at the end of a word. With no vowel, five letters do not stay blocked: they give a clear bounce.
Idgham Mutajanisayn First letter with no vowel: among ت, د and ط; among ث, ذ and ظ; or from ب into م. A ṭā before a tā keeps its heaviness: the merger there is incomplete. A letter with no vowel, then a letter from the same place in the mouth: the first merges into the second.
Idgham Mutaqaribayn In Hafs, two cases: a lām with no vowel before a rā, and the qāf before the kāf (77:20). The Mushaf shows them: no sukoon on the first letter, a shaddah on the second. Except in 83:14, where a short pause (sakt) prevents the merger. A letter with no vowel, then a letter from a neighbouring place: the first merges into the second.

By ear: two words that sound alike

Two words that sound alike: one is read with Qalqalah, the other with Idgham Mutajanisayn. Listen for the difference.
