Ishmam and rawm are two refined ways of stopping on a word in Quran recitation. Normally you stop with a plain sukun, cutting the last vowel completely. With rawm, you pronounce a small part of that final vowel in a soft voice. With ishmam, you stop with a full sukun and then round your lips silently, as a visual hint that the word ended in a damma. Both are optional, both are taught in the reading of Hafs ‘an ‘Asim, and both are easiest to learn by ear in one-to-one Tajweed lessons, because the difference between a correct rawm and a mistake is only a fraction of a vowel.
This guide shows exactly which word endings allow each stop, where they are not allowed at all, and how they change the rules you already know for madd, ra and qalqalah.
Key takeaways
- Rawm = a partial, quiet vowel you can hear. Ishmam = a silent lip rounding you can only see.
- A final damma allows sukun, rawm or ishmam; a kasra allows sukun or rawm; a fatha allows sukun only.
- Rawm cancels the temporary sukun, so a madd before it goes back to 2 counts; ishmam keeps all three lengths.
- Ta marbuta, the meem of the plural and temporary vowels are stopped with a plain sukun.
What Rawm and Ishmam Actually Are
Both stops show the listener which vowel the word carried before the stop. They never change the meaning; they simply add precision.
Rawm: a whispered fragment of the vowel
In rawm you say most of the word normally, then give the last letter only part of its vowel, often described as about a third of it. The voice drops and the vowel is short and soft. A person sitting next to you hears it; someone across the room may not. That is the point: it is a gentle signal, not a full vowel.
If you pronounce the whole vowel, you have not stopped at all. If you add the noon sound of tanween, that is also wrong, because tanween is always dropped when you stop.
Ishmam: a silent shape of the lips
In ishmam the last letter takes a complete sukun. Immediately afterward, you bring your lips forward and round them, the way they move for a damma, without making any sound. Because ishmam is purely visual, a listener who cannot see you will hear nothing different from a plain sukun.
The word ishmam has other meanings in other readings. In some qiraat it describes mixing a kasra with a damma in words such as قِيلَ, or blending the sound of sad with zay in الصِّرَاطَ. In Hafs, when teachers talk about ishmam at the end of a word, they mean the silent lip rounding described here.
Which Endings Allow Rawm and Ishmam
The deciding factor is the vowel on the last letter in continuous reading. This table covers every common case in Hafs by way of al-Shatibiyyah:
| How the word ends | Example | Plain sukun | Rawm | Ishmam |
|---|---|---|---|---|
| Damma | نَسْتَعِينُ | Yes | Yes | Yes |
| Tanween with damma | عَلِيمٌ | Yes | Yes (no noon sound) | Yes |
| Built-in damma | مِن قَبْلُ | Yes | Yes | Yes |
| Kasra | الرَّحِيمِ | Yes | Yes | No |
| Tanween with kasra | مُبِينٍ | Yes | Yes (no noon sound) | No |
| Fatha | الْعَالَمِينَ | Yes | No | No |
| Tanween with fatha | رَحِيمًا | Stop on an alif | No | No |
So the quickest rule of thumb is: damma gets three options, kasra gets two, fatha gets one.
Where neither stop is allowed
Some endings look as if they should qualify, but they do not:
- Ta marbuta that becomes ha, as in الْجَنَّةِ or رَحْمَةٌ. When you stop, the letter itself changes to a ha sakinah, and the vowel has nothing left to sit on.
- The meem of the plural, as in عَلَيْهِمْ or لَهُمْ. In Hafs this meem is sakin, so there is no vowel to hint at. Even when it takes a damma to join the next word, as in لَهُمُ الْأَرْضُ, you stop on it with a plain sukun.
- Temporary vowels, added only to avoid two sakin letters meeting. If you stop on قُمِ in قُمِ اللَّيْلَ, the kasra disappears and you say قُمْ.
- Words whose last letter is sakin anyway, such as لَمْ or قَدْ.
Scholars also discuss the ha of the pronoun (as in بِهِ or أَمْرُهُ). A widely taught position is that rawm and ishmam are avoided on it when it comes after a damma, a kasra, a waw or a ya, and allowed otherwise, as in مِنْهُ. Teachers differ slightly on this point, so follow the way your own teacher received it.
Now test yourself on the endings above before reading how these stops change other rules.

How Rawm and Ishmam Change Other Tajweed Rules
This is the part most short explanations skip, and it is exactly what examiners check.
Madd before the last letter
When you stop on الرَّحِيمِ with a plain sukun, the ya before the meem becomes madd arid lissukun, which you may read with 2, 4 or 6 counts. With rawm, the meem is not truly sakin, so the madd behaves as in continuous reading and is read with 2 counts only. With ishmam on a word like نَسْتَعِينُ, the sukun is complete, so 2, 4 or 6 all stay valid. Our guide to madd arid lissukun covers these lengths in more detail.
The same logic applies when the word ends in a hamza after a madd, as in السَّمَاءُ. With a plain sukun, the madd can be stretched further because of the stop. With rawm, you go back to the length you use for madd muttasil in continuous reading (4 or 5 counts) and keep it consistent.
The letter ra
Ra follows its own vowel when it has one, and the letters before it when it is sakin. That makes rawm audible in a surprising way. Stop on وَالْعَصْرِ with a plain sukun and the ra is heavy, because the letter before it is sakin and the one before that has a fatha. Stop with rawm and the partly pronounced kasra makes the ra light. The same happens with وَالْفَجْرِ and لَيْلَةِ الْقَدْرِ. Review the background in our article on the rules of ra.
Qalqalah
Qalqalah happens on a qalqalah letter that is sakin. Stop on الْبُرُوجِ with a plain sukun and the jeem bounces, often more strongly than in the middle of a word. Stop with rawm and there is no qalqalah, because the jeem keeps part of its vowel.
The One Place Ishmam Appears in Continuous Reading
In Hafs there is a single word where ishmam is applied without stopping: تَأْمَنَّا in Surah Yusuf (12:11). The word is originally تَأْمَنُنَا, with two noons. Hafs by way of al-Shatibiyyah reads it in one of two ways:
- Idgham with ishmam: merge the two noons and round the lips during the merged noon. This is the way most students learn first.
- Rawm (also called ikhtilas here): pronounce the first noon with a shortened damma, without full merging.
It belongs to the same small family of unusual words as the eased hamza in our guide to tashil in Hafs and the tilted vowel in imalah in Hafs. Together with the four places of sakt, these words often come up in Ijazah exams.
How to Practice These Stops
- Start with Al-Fatiha. It has all three cases: الرَّحِيمِ (kasra), نَسْتَعِينُ (damma) and الْعَالَمِينَ (fatha). Practice each ending three ways and say aloud which stops are allowed.
- Use a mirror for ishmam. If you cannot see your lips round, neither can your listener.
- Record your rawm. Play it back. If it sounds like a full vowel, shorten it; if you cannot hear it at all, it has become a plain sukun.
- Do not overuse them. A plain sukun is the default and is always correct. Rawm and ishmam are refinements you use with intention, not on every ayah.
- Get them checked. These stops depend on tiny differences in timing and voice. A teacher in a structured Tajweed course will hear in seconds whether your rawm is too long or your ishmam has accidentally gained a sound.
Frequently Asked Questions
Are rawm and ishmam obligatory?
No. Stopping with a plain sukun is always correct, and rawm and ishmam are optional refinements. They are, however, part of complete Tajweed knowledge, and students preparing for an Ijazah are expected to know where they are allowed and to perform them correctly.
Can a listener hear ishmam?
No. Ishmam is only a movement of the lips after the sukun, so it can be seen but not heard. Rawm, by contrast, can be heard by someone close to you because part of the vowel is pronounced.
Why is rawm not used on fatha in Hafs?
Scholars explain that the fatha is light and quick, so a portion of it is hard to separate from the full vowel. In the reading of Hafs by way of al-Shatibiyyah, a final fatha is therefore stopped on with a plain sukun only.
Does rawm change the length of madd arid lissukun?
Yes. With rawm the last letter keeps part of its vowel, so the temporary sukun that caused the longer madd is gone. The madd returns to its natural 2 counts, exactly as in continuous reading.
How do I learn ishmam and rawm correctly?
Learn the table of allowed endings, then practice on familiar words with someone who can watch and listen. Because the details are so fine, most students master them fastest with live correction, which is why our Tajweed lessons online include stopping practice on real ayahs.
