Qalqalah

Definition of Qalqalah

Linguistically: agitation and movement — an Arabic word describing something that shakes or vibrates.

Technically: a vibration produced at the articulation point (makhraj) of a silent (sākin) letter, strong enough that a clear "bounce" or echo is heard — whether that letter is silent by its original vowel-less state, or made silent temporarily because of stopping (waqf) at the end of a word.

The Letters of Qalqalah

There are five Qalqalah letters, remembered by the mnemonic phrase "Qutb Jad" (قُطْبُ جَدً):

• ق Qaf
• ط Ttaa
• ب Baa
• ج Jeem
• د Daal

These letters share two articulation qualities: Jahr (voicedness) and Shiddah (plosiveness/strength). Because of this, the sound gets "trapped" at the point of articulation when the letter is silent, and the tongue needs a slight extra push to release that trapped sound — producing the audible bounce known as Qalqalah.

The Categories of Qalqalah

Qalqalah is divided into three levels according to its strength:

﴾ يَقْطَعُونَ ﴿ (Al-Baqarah: 27) — ﴾ يَجْعَلُونَ ﴿ (Al-Baqarah: 19)
﴾ أَبْصَارِهِمْ ﴿ (Al-Baqarah: 7) — ﴾ يَدْعُونَ ﴿ (Yunus: 66)

Stopping on ﴾ الْفَلَقْ ﴿ (Al-Falaq: 1) — Stopping on ﴾ أَحَدْ ﴿ (Al-Ikhlas: 1)
Stopping on ﴾ الْحَقّْ ﴿ — Stopping on ﴾ الْكِتَابْ ﴿

Stopping on ﴾ تَبَّتْ يَدَا أَبِي لَهَبٍ وَتَبَّ ﴿ (Al-Masad: 1) — stopping on a shaddah-doubled ﴾ الْحَقّْ ﴿

A Note Worth Remembering

Qalqalah is an inherent quality of these five letters that never leaves them whenever they are silent — whether in a noun, a verb, or a particle. Qalqalah does not appear when the letter carries a vowel (fatha, damma, or kasra); it only appears when the letter is silent.
