In Tajweed, Sukoon holds a profound significance. It not only signifies a vowel-less state but also governs specific rules of Quranic recitation, such as Izhar and Idgham. Mastering Sukoon is crucial for achieving accurate and melodious Quranic recitation, emphasizing both linguistic precision and spiritual expression.
Let’s dive deeper and discuss this in more detail:
Sukoon Meaning in Arabic and Its Role in Written Script
The word sukoon (سُكُون) comes from the Arabic root س-ك-ن, meaning stillness, rest, or tranquility. In linguistic grammar, it refers to the absence of motion—specifically, the absence of a short vowel (harakah) on a consonant.
In Arabic script, the sukoon is written as a small open circle (ْ) placed above the letter it affects. Unlike the three vowel markers—fathah (َ), kasrah (ِ), and dhammah (ُ)—sukoon carries no sound itself.
The letter beneath a sukoon is called a “sakin” letter (حرف ساكن), meaning a resting or still letter. It cannot be initiated with or ended upon without applying specific Tajweed rules.
What is Sukoon in Tajweed?
In the science of Tajweed, Sukoon (ْ) is the state of a letter when it is read without a vowel (i.e., without a Dammah, Fathah, or Kasrah).
A silent letter is pronounced without being followed by any vowel, and it appears in the Quran with a small “haa” حـ symbol above the letter.
Sukoon meaning in the Quran
Sukoon is the opposite of movement. It is the opposite of fatha, kasra, and dhammah. When pronouncing the consonant letter, we do not open the mouth as we open it with fatha, nor do we lower it as we lower it in kasra, nor do we close it as we close it with dhammah. That Sukoon, in short, is the complete absence of movement.
What Are the Rules in Tajweed That Sukoon Activates?
Sukoon is the anchor of several major Tajweed rules. When the Noon sakinah (نْ) or Tanwin appears in a word, four rules are activated depending on the next letter. Similarly, when Meem sakinah (مْ) appears, three distinct rulings apply.
| Sakin Letter | Possible Rules Activated | Key Factor |
| Noon Sakinah / Tanwin | Idhar, Idgham, Iqlab, Ikhfa | Identity of the following letter |
| Meem Sakinah | Idgham Mithlayn, Ikhfa Shafawi, Idhar Shafawi | Identity of the following letter |
| Qalqalah Letters (ق ط ب ج د) | Qalqalah (echo/bounce) | Sakin position: mid-word or end-word |
| Letters with Madd | Madd rules (elongation) | Hamzah or Sukoon following the Madd |
Understanding sukoon in Tajweed as a trigger—not just a grammatical marker—is the key shift every serious student must make.

Sukoon letters in Tajweed:
In the context of Tajweed, “Sukoon letters” refer to letters in the Arabic script that carry a Sukoon (ْ) symbol above them, indicating that they are to be pronounced without any vowel sound. These letters are known as “ساكنة” (sakina), meaning “silent” or “resting.”
Here are a few points to elaborate on Sukoon letters:
Sukoon Symbol: The small circular mark (ْ) placed above a letter to denote that it should be read without any vowel.
Pronunciation: When a letter carries a Sukoon, it is pronounced without any added vowel sound. For example, in the word “يَذْهَبُ”, the letter “ذ” (dhal) carries a Sukoon and is pronounced without any vowel.
Understanding Sukoon and its rules helps in achieving accurate and beautiful recitation of the Quran, adhering to the principles of Tajweed.
Shaykhi Academy’s exclusive Al-Menhaj Book methodology—developed by founder Luqman ElKasabany—combined with the Noorani Qaida with Tajweed Course offers a systematic approach for non-Arabic speakers to master these sukoon-related rules from the very beginning.

Sukoon symbol in the Quranic Script:
Sukoon symbol in the Quran is a small head of “حـ” above the letter. If we find it, this indicates the absence of movement for this letter, just as the absence of all symbols from the letter means that it is a Sukoon.
Examples of Sukoon in the Quran
There are three types of Sukoon in the Holy Quran (the apparent Sukoon – the invisible Sukoon – the occasional Sukoon)
We look at examples of each of them
1- The apparent Sukoon:
It is the Sukoon which drawn on the letter with the symbol (small حـ)
For Example: In the Almighty’s saying
((صِرَٰطَ ٱلَّذِينَ أَنۡعَمۡتَ عَلَيۡهِمۡ
(the path of those whom You have favored on them)
The word (أَنۡعَمۡتَ) has a Sukoon appearing on the letter م.
2- The non-apparent:
That is, not drawn on the letter, so it is devoid of any diacritics, such as:
The three vowel letters
Which are silent even though they are devoid of signs of Sukoon.
For example, God Almighty says in Surat Al-Naba’
(And He spoke correctly)
(وَقَالَ صَوَابًا)
The Sukoon here is on the maad, so it is not decreed.
Letters followed by Tajweed rulings
Such as the rulings on idgham, ikhfaa, and iqlab with the noon sakinah, and the rulings on the meem sakinah in idgham, and ikhfaa shafawi. In these examples, the Sukoon comes without being apparent.
For Example: The Sukoon in the rule of the meem sakinah in the Almighty’s saying:
“So who does it?”
“فَمَنْ يَعْمَلْ”
3- Accidental Sukoon
It is an unoriginal sukun, as it is accidental due to the pause, and it occurs in the last letter of the word on which we stop.
For Example, the ending words in al fatiha
الْعَالَمِينَ) – الرَّحِيمِ – (نستعين

Alifs with Sukoon rules in Tajweed
In the Quran, certain Alifs with a Sukoon symbol (°) are pronounced differently depending on whether the recitation is paused or continued. These rules ensure accurate recitation, as seen in words like “أنا” and others where the Alif modifies pronunciation.
For instance, “أناْ لكم” is pronounced “أنَ لكم” when continuing but “أنا … لكم” when stopping. Understanding these rules is essential for mastering Quranic recitation and adhering to Tajweed principles, ensuring the text is recited as intended.
The alif is one of the most colorful letters, as it appears clearly in some places and in other places it is completely hidden. What are the rules for the sakinah alif in the Quran?
There are seven alifs in the Quran that are heard when you stop, and are silent when you continue the recitation. This alif is indicated by the circular shape that resembles a sukoon above it: (°)
A- All occurrences of the word “I” (أنا) that carry this symbol.
When you stop, you pronounce the alif, mada tabi’i (for two counts), but when you continue the recitation, you pronounce the alif only with a fatha.
for example:
The Holy Verse (أناْ لكم)
When you continue, it is: (أنَ لكم)
When you stop, it is: (أنا … لكم)
This rule applies to the following words in their own way:
1- In this verse (لكناْ هو)
When continuing, it is read as follows: (لاكنَّ هو)
When you stop, it is: (لاكنّا … هو)
2-In this verse (الظنوناْ (10) هنالك)
When continuing, it is read as follows: (الظنونَ هنالك)
When you stop, it is: (الظنونا … هنالك)
3-In this verse (الرسولاْ (66) وقالواْ)
When continuing, it is read as follows: (الرسولَ و قالواْ)
When you stop, it is: (الرسولا … و قالواْ)
4-In this verse (السبيلاْ (67) ربنا)
When continuing, it is read as follows: (السبيلَ ربّنا)
When you stop, it is: (السبيلا … ربّناْ)
There are some cases in which scholars have permitted stopping at two cases for alif, such as:
5- In this verse (سَلَٰسِلَاْ وَأَغْلَٰلًا)
When continuing, it is read as follows: (سلاسلَ و أغلالاً)
When you stop, it is: (سلاسلا … و أغلالاً) or (سلاسلْ … و أغلالاً)
We notice two special cases of the alif, which are in the word “Qawarira” in Surah Al-Insan, verse 16, where it is never pronounced with a long vowel when stopping. It is always pronounced with a fatha when continuing. This also applies to all occurrences of the word “Thamud” (which contains this silent alif).
Note the following:
6- In this verse
((وَأَكْوَابٍ كَانَتْ قَوَارِيرَا (15) قَوَارِيرَ مِن فِضَّة
When continuing, it is read as follows: (قواريرَ قواريرَ)
When you stop, it is: (قواريرا … قواريرَ) or (قواريرا … قواريرْ)
B- All occurrences of the word “Thamud” like the verse (وثموداْ)
when continuing: (وثمودَ)
when stopping: (وثمودْ)
Is Sukoon in Arabic Different from the Sukoon in Quran and Tajweed?
Yes, the Sukoon in Arabic grammar and the Sukoon in Quranic Tajweed are essentially the same in indicating the absence of a vowel on a letter, but they differ in application.
In Arabic grammar, Sukoon marks a consonant without a vowel, aiding in pronunciation and grammatical rules.

In Tajweed, Sukoon also denotes a vowel-less letter but plays a critical role in specific recitation rules, such as Izhar and Idgham, ensuring proper and beautiful Quranic recitation.
The Symbol of Sukoon in the Quran and tajweed (“حـ” above the letter) is also different from the symbols in Arabic (ْ above the letters).
