Both are written with an alif at the start of a word, which is why students mix them up. The difference shows up as soon as you read a full sentence: one hamza stays, the other disappears. Getting it wrong either adds a sound that should not be there or swallows one that should.
Hamzat al-qat': the "cutting" hamza
This is a full consonant, a short catch in the throat. It is written with a small hamza sign: أ on top of the alif for fatha or dammah, إ below it for kasrah. You always pronounce it, whether you start from it or reach it mid-sentence.
- أَنْعَمْتَ (an'amta)
- إِيَّاكَ (iyyāka)
- أُولَٰئِكَ (ulā'ika)
- قَالَ إِنِّي: the hamza is clearly heard after قَالَ
Hamzat al-wasl: the "connecting" hamza
This hamza exists only to let you start a word whose first letter has a sukoon, since Arabic cannot begin with a sukoon. In the Madinah mushaf it is marked with a small sign like the head of a ص on the alif (ٱ). Some prints just show a plain alif.
In the middle of a sentence it is dropped, and the vowel of the previous word runs straight into the next consonant:
- بِسْمِ ٱللَّهِ → bismil-lāh
- ٱهْدِنَا ٱلصِّرَاطَ → ihdinaṣ-ṣirāṭ
- وَٱسْتَغْفِرُوا → wastaghfirū
Where hamzat al-wasl appears
You do not have to guess. It only appears in specific places:
- The article ال: ٱلْحَمْدُ، ٱلنَّاسِ.
- Seven nouns: ٱسْم، ٱبْن، ٱبْنَة، ٱمْرُؤ، ٱمْرَأَة، ٱثْنَان، ٱثْنَتَان.
- Imperative of three-letter verbs: ٱقْرَأْ، ٱدْخُلُوا، ٱذْهَبْ.
- Past tense, imperative and verbal noun of five- and six-letter verbs: ٱسْتَغْفَرَ، ٱنْطَلَقُوا، ٱسْتِغْفَار.
Four-letter verbs like أَكْرَمَ، أَنْزَلَ start with hamzat al-qat', which is a common point of confusion.
Which vowel when you start?
| Where | Start with | Example |
|---|---|---|
| ال | fatha | ٱلْحَمْدُ → al-ḥamdu |
| The seven nouns | kasrah | ٱسْمُ → ismu |
| Verbs, third letter has dammah | dammah | ٱدْخُلُوا → udkhulū; ٱنْظُرْ → unẓur |
| Verbs, third letter has fatha or kasrah | kasrah | ٱذْهَبْ → idh-hab; ٱضْرِبْ → iḍrib |
| Five- and six-letter verbs | kasrah | ٱسْتَغْفِرُوا → istaghfirū |
There are a few verbs where the third letter shows a dammah but you still start with kasrah, because the dammah is not original: ٱمْشُوا، ٱبْنُوا، ٱقْضُوا، ٱئْتُوا. A teacher will point these out when you meet them.
When a sukoon meets a connecting hamza
If the word before ends in a sukoon, and the hamzat al-wasl drops, two sukoons would meet. Arabic solves this by adding a vowel to the first word, usually kasrah: قُلِ ٱللَّهُمَّ, وَلَقَدِ ٱسْتُهْزِئَ. Many mushafs print this extra vowel for you. If the first word ends in a madd letter, the madd is simply dropped in pronunciation: فِي ٱلْأَرْضِ is read fil-arḍ, not fī al-arḍ.
Common mistakes
- Pronouncing the connecting hamza mid-sentence: bismi al-lāh.
- Dropping a real hamza: reading قَالَ إِنِّي as qālinnī.
- Stretching a madd before a connecting hamza: فِي ٱلْأَرْضِ as fīīl-arḍ.
- Starting a word with the wrong vowel, such as idkhulū instead of udkhulū.
This rule ties together sun and moon letters, sukoon and where to stop and start. Our teachers usually cover it in the last stage of Noorani Qaida and revisit it in the tajweed course.
Questions parents and students ask us
What is hamzat al-wasl?
It is a connecting hamza at the start of certain words. It is pronounced only when you begin reading from that word and is silent in the middle of a sentence.
What is hamzat al-qat'?
It is a full hamza that is always pronounced, written with the hamza sign as أ or إ.
Is the alif in ال a hamzat al-wasl?
Yes. When you start with ال you say 'al', but in the middle of a sentence the alif is silent.
How do I know which vowel to start with?
Start ال with fatha, the seven special nouns with kasrah, and verbs with dammah if the third letter has an original dammah, otherwise with kasrah.
