The Rules of the Letter Ra in Tajweed: When It Is Heavy and When It Is Light
The letter ر is heavy when it carries a fatha or damma and light when it carries a kasra. When it has a sukoon, look at the vowel before it: after a fatha or damma it is heavy, after a kasra it is usually light, with a small number of special cases that follow their own rules.
Of the letters that can be heavy or light, ra causes the most questions because its sound changes with its surroundings. The good news is that a short set of rules covers most of the words you will read. This guide explains those rules in order, shows the special cases, and offers a simple way to practise. It follows the Hafs recitation.
Start with the ra's own vowel
| Vowel on the ra | Sound | Example |
|---|---|---|
| Fatha | Heavy (tafkheem) | رَبَّنَا |
| Damma | Heavy (tafkheem) | رُسُلٌ |
| Kasra | Light (tarqeeq) | رِزْقًا |
When the ra carries its own vowel, that vowel usually decides the sound. A heavy ra uses a fuller mouth, like the heavy letters in our guide to tafkheem and tarqeeq, while a light ra keeps the tongue relaxed.
When the ra has a sukoon
A ra with a sukoon takes its sound from the letter before it:
- After a fatha or damma: heavy. Examples: مَرْيَمَ and ٱلْغُرْفَةَ.
- After a kasra: light. Example: فِرْعَوْنَ.
- After a silent ya: light when you stop on the word, as in خَيْر.
The special cases
Two situations need extra care:
- A silent ra after a kasra, followed by a heavy letter in the same word. Here the ra is heavy. The classic examples are قِرْطَاسٍ (6:7), إِرْصَادًا and فِرْقَةٍ (9:107 and 9:122).
- A small group of words where both sounds are allowed, with the light sound preferred in some of them. Teachers usually list five: فِرْقٍ, فَأَسْرِ, يَسْرِ, وَنُذُرِ and ٱلْقِطْرِ.
These cases are few, but they are exactly where a teacher’s modelling is most valuable.
When you stop on a word
When you stop on a word ending in a ra, the sound can change, because the last letter takes a sukoon and then follows the “letter before it” rule. A word like ٱلْأُمُورُ or ٱلْكُفْر is an example your teacher can demonstrate. If you are new to stopping rules, see our guide to waqf first.
A simple practice method
- Pick ten words with ra from a page you know and sort them into heavy and light.
- Say each pair slowly: heavy rise of the tongue for fatha and damma, relaxed for kasra.
- Record yourself and listen for the difference.
- Check the special cases with a teacher.
Many learners also find that ra is where an accent shows most, so it helps to listen to a reciter first and copy the shape of the mouth.

Frequently Asked Questions
Is the ra always heavy after a fatha?
If the ra itself has a fatha or damma, it is heavy. If it is silent, it follows the letter before it, so after a kasra it is usually light.
Why is the ra in قِرْطَاس heavy if it is after a kasra?
Because the ra is silent and followed by a heavy letter (ط) in the same word. This is one of the special cases that teachers list separately.
Which words allow both sounds?
A small group, usually listed as five words. Your teacher will show you which ones and which sound they prefer.
