Hamzatul Wasl vs Hamzatul Qat: Rules with Examples

Have you noticed that بِسْمِ اللَّهِ is read bismillāh, with no “a” before the laam, while اللَّهُ أَكْبَرُ at the start of a sentence is read Allāhu akbar? The difference comes from a small but important letter: the hamzah. Arabic has two kinds, and knowing them is essential for joining words correctly in recitation.

Hamzatul qat’ is always pronounced. Hamzatul wasl is pronounced only when you start reading from that word and disappears when you join it to the word before. This guide explains both, how the Quran writes them, the rules for which vowel to use when starting with hamzatul wasl, and plenty of examples. It is a key step for anyone who wants to learn Quran online and read whole ayahs smoothly.

What Is a Hamzah?

A hamzah (ء) is a short catch in the throat, like the break in the middle of “uh-oh”. It is made from the deepest point of the throat, which our guide to makharij al huroof describes. In writing, a hamzah can sit on an alif (أ إ), on a waw (ؤ), on a yaa-shaped seat (ئ) or on its own (ء).

What Is Hamzatul Qat’?

Qat’ (قَطْع) means “cutting”. Hamzatul qat’ is a hamzah that is always pronounced, whether you start from it or join it to the previous word. It “cuts” the flow with a clear glottal stop.

Examples:

In the Mushaf it is written as a small hamzah on top of the alif (with fatha or damma) or below it (with kasra). Even in the middle of a phrase, as in وَإِيَّاكَ نَسْتَعِينُ, you still pronounce the hamzah: wa iyyāka, not wayyāka.

What Is Hamzatul Wasl?

Wasl (وَصْل) means “joining”. Hamzatul wasl is a hamzah that is pronounced only at the start of reading. When the word is joined to the word before it, the hamzah and its vowel disappear, and you connect straight from the last sound of the previous word.

In the Madani (Uthmani) Mushaf it is shown by a small ṣād-like sign on top of the alif (ٱ). Some print styles leave the alif bare instead. Either way, a hamzah sign is never written on it.

Where Does Hamzatul Wasl Appear?

It is found in a limited set of places, which makes it easy to learn:

1. The definite article ال: ٱلْكِتَاب, ٱلشَّمْس.
2. Ten nouns: ٱسْم (name), ٱبْن (son), ٱبْنَة (daughter), ٱمْرُؤ (man), ٱمْرَأَة (woman), ٱثْنَانِ and ٱثْنَتَانِ (two), ٱسْت, ٱبْنُم and ٱيْمُن (the last three are rare).
3. Command verbs of certain patterns: ٱهْدِنَا (guide us), ٱقْرَأْ (read), ٱدْخُلُوا (enter), ٱذْكُرُوا (remember).
4. Past and verbal-noun forms of some longer verbs: ٱسْتَغْفَرُوا, ٱنْطَلَقُوا, ٱسْتِغْفَار.

You do not need to master the grammar. Just look for the wasl sign on the alif.

Which Vowel Do You Use When Starting with Hamzatul Wasl?

When you begin reading from a word with hamzatul wasl, you must give it a vowel. The rules are:

A quick tip for verbs: count to the third letter of the word, including the alif. If it has a damma, start with u; otherwise start with i.

What Happens When Hamzatul Wasl Follows a Sukoon?

If the word before ends in a sukoon and the next word starts with hamzatul wasl, the two sukoons would meet, which Arabic does not allow. The first word’s final letter takes a short vowel to join smoothly, usually a kasra:

• قُمِ ٱللَّيْلَ qumil-layl (73:2), where the meem of qum gets a kasra.
• وَلَقَدِ ٱسْتُهْزِئَ wa laqadis-tuhzi’a (6:10).

The Mushaf prints this helping vowel for you, so read what is written.

What Happens When a Long Vowel Meets Hamzatul Wasl?

If the previous word ends in a long vowel, the long vowel is shortened when joined, because the next letter has a sukoon. For example, فِي ٱلْأَرْضِ is read fil-arḍ, not fī al-arḍ, and وَقَالَا ٱلْحَمْدُ is read wa qālal-ḥamdu. This is one of the most common joining mistakes beginners make.

How Does Hamzatul Wasl Work with Al-Fatiha and Daily Prayers?

You meet hamzatul wasl many times in every prayer:

• بِسْمِ ٱللَّهِ → bismillāh (joined, no hamzah).
• ٱلْحَمْدُ لِلَّهِ → al-ḥamdu (when starting the ayah).
• ٱهْدِنَا ٱلصِّرَاطَ ٱلْمُسْتَقِيمَ → ihdinaṣ-ṣirāṭal-mustaqīm, where both following wasl hamzahs disappear and the long vowel of nā is shortened.

Getting these joins right is a big part of sounding fluent. Our guide to sun and moon letters explains what happens to the laam after the hamzah of al-.

What Mistakes Do Learners Make with Hamzah?

• Pronouncing hamzatul wasl in the middle of a phrase: bismi Allāh instead of bismillāh.
• Dropping hamzatul qat’: wayyāka instead of wa iyyāka.
• Using the wrong starting vowel: adkhulū instead of udkhulū.
• Not shortening a long vowel before wasl: fī al-arḍ instead of fil-arḍ.

These rules are taught step by step in the Noorani Qaida and practised with real ayahs in our online Tajweed course.
