Every time you read وَكَانَ اللَّهُ عَلِيمًا حَكِيمًا (An-Nisa 4:17), you pass over a small puzzle. The Name اللَّهُ ends in a damma. The two Names after it, عَلِيمًا and حَكِيمًا, end in a fatha with tanween. Something changed those endings, and that something is the first word of the phrase: kana.
Kana and its sisters (kana wa akhawatuha) sit among the most common grammar patterns in the Quran, and one rule runs the whole family. Learn the rule once and you will start seeing it on page after page, in words you have recited since childhood.
What you will learn in this guide:
- What kana does to a simple nominal sentence, and why the second word changes its ending
- All 13 verbs in the family, with a reference table you can screenshot
- The beginner mistake that nearly everyone makes, and the tell that fixes it
- Ten verified Quranic examples, each with the ism and khabar named
- A 60-second exercise, a live converter and a six-question quiz
What Are Kana and Its Sisters in Arabic?
Start with the sentence type you already know. A jumla ismiyya, the nominal sentence, is built from two raised words: a mubtada (the topic) and a khabar (what you say about it). الْبَابُ مَفْتُوحٌ means “the door is open”. Both words end in a damma.
Kana is a verb that walks into that sentence and rearranges it. It adds time (“was”, “became”, “is not”) and it does one very specific thing to the endings. Its sisters are a set of verbs that behave in exactly the same way. Classical grammarians group them in one chapter, kana wa akhawatuha, and Ibn Malik gives them their own section in the Alfiyya.
Think of the nominal sentence as a two-room house. Kana moves in, keeps the first room exactly as it was, and repaints the second.
What Does Kana Do to the Sentence?
The rule fits in one line: the mubtada stays raised and is now called the ism of kana; the khabar is lowered to the accusative and is now called the khabar of kana.
Look at the gears in order. Without kana, both words are marfu’, with a damma. With kana, the first word keeps its damma but the second gets a fatha (or tanween fathatayn). The change is tiny on the page and large in what it tells you about the sentence. If you want the full picture of why endings move, the guide to i’rab and noun endings is the place to read next.
Here is the same move on six sentences, so the pattern sinks in through repetition rather than through memorising a rule.
| Arabic | Transliteration | Meaning |
|---|---|---|
| الْبَابُ مَفْتُوحٌ | al-babu maftuhun | The door is open (no kana) |
| كَانَ الْبَابُ مَفْتُوحًا | kana al-babu maftuhan | The door was open |
| أَصْبَحَ الْبَابُ مَفْتُوحًا | asbaha al-babu maftuhan | The door became open |
| لَيْسَ الْبَابُ مَفْتُوحًا | laysa al-babu maftuhan | The door is not open |
| مَا زَالَ الْبَابُ مَفْتُوحًا | ma zala al-babu maftuhan | The door is still open |
| مَا دَامَ الْبَابُ مَفْتُوحًا | ma dama al-babu maftuhan | As long as the door is open |
One more note on the tense of kana. When it comes with a Name of Allah, as in 4:17, translators usually write “ever”. Grammarians and mufassirin commonly explain that kana there does not lock the attribute in the past: Allah’s knowledge and wisdom are not a thing that used to be. That is why a flat “was” sometimes sounds wrong in English even though the verb is in the past form.
Which Verbs Are the Sisters of Kana?
Thirteen verbs make up the family in the traditional count. They fall into natural groups, and the groups are easier to remember than a flat list: times of day (asbaha, amsa, adha, zalla, bata), becoming (sara), negation (laysa), continuity (the four ma-verbs) and duration (ma dama).
| Arabic | Transliteration | Meaning |
|---|---|---|
| كَانَ | kana | was; used to be; ever |
| أَصْبَحَ | asbaha | became; was in the morning |
| أَمْسَى | amsa | became; was in the evening |
| أَضْحَى | adha | became; was in the forenoon |
| ظَلَّ | zalla | remained, continued (through the day) |
| بَاتَ | bata | spent the night; became |
| صَارَ | sara | became |
| لَيْسَ | laysa | is not |
| مَا زَالَ | ma zala | still; has not ceased to |
| مَا انْفَكَّ | ma infakka | still; has not ceased to |
| مَا فَتِئَ | ma fati’a | still; has not ceased to |
| مَا بَرِحَ | ma bariha | still; has not ceased to |
| مَا دَامَ | ma dama | as long as |
Notice the four continuity verbs all begin with a negative ma. That is the quiet trick of the group: a negative on the front of a verb that itself means “to cease”. Two negatives make a positive, so مَا زَالَ الطَّالِبُ مُجْتَهِدًا means “the student is still diligent”, not “the student is not diligent”.
These verbs also conjugate like any other, so you will meet يَكُونُ (yakunu, he is/will be) and كُونُوا (kunu, be!) as well. If the conjugation side feels shaky, the guide to Arabic verb conjugation across past, present and future covers it.
What Mistake Does Almost Everyone Make at First?
Nearly everyone mixes up the endings: they say the word for the sentence’s second half exactly as it was before kana arrived, leaving it with a damma. The result sounds natural to an English ear, because English has no case endings, and wrong to an Arabic one.
The tell that fixes it for good is to ask one question the moment you see kana or a sister: which word is the second room? Whatever fills that role takes a fatha. The first word never moves. Say the pair out loud, كَانَ الْبَابُ مَفْتُوحًا, and listen for the open “aa” sound landing on the last word.
The second trap is laysa. Learners reach for it because it means “not”, then confuse it with the particle la. Laysa is a verb in the family, so it needs an ism and a khabar with the same endings as kana. La simply negates and changes nothing about the endings.
What If the Ism or the Khabar Is Not a Simple Word?
Real Quranic sentences rarely look as tidy as كَانَ الْبَابُ مَفْتُوحًا. Three variations cover most of what you will meet.
The ism can be hidden inside the verb. In كُونُوا أَنصَارَ اللَّهِ, the ism of kunu is the waw of the group, a pronoun attached to the verb. The khabar is أَنصَارَ, which takes the fatha.
The khabar can be a prepositional phrase. When the khabar comes with a preposition, the noun after it carries a kasra because of the preposition, but the phrase as a whole still fills the khabar slot. Learn how those phrases work in the guide to harf al-jarr.
The order can flip. In لَيْسَ كَمِثْلِهِ شَيْءٌ the khabar comes first and the ism comes last. You can tell which is which not by position but by the ending: the word with the damma is the ism.
The mirror image of this chapter is inna and its sisters, which do the opposite: they put the subject in the accusative and leave the predicate raised. The guide to the particles inna, qad and laqad starts that story.
How Do Kana and Its Sisters Appear in the Quran?
Ten ayat, each checked against the mushaf. In every one, find the ism first, then the khabar.
Al-Baqarah 2:213
كَانَ النَّاسُ أُمَّةً وَاحِدَةً
“Mankind was one community.”
Ism kana: النَّاسُ (damma). Khabar kana: أُمَّةً (tanween fatha). The word وَاحِدَةً describes it and takes the same ending.
An-Nisa 4:17
وَكَانَ اللَّهُ عَلِيمًا حَكِيمًا
“And Allah is ever Knowing, Wise.”
Ism: اللَّهُ. Khabars: عَلِيمًا and حَكِيمًا, both lowered to the fatha. This is the phrase from the opening of the article.
Al-Isra 17:11
وَكَانَ الْإِنسَانُ عَجُولًا
“And man has ever been hasty.”
Ism: الْإِنسَانُ. Khabar: عَجُولًا. A whole portrait of human nature in three words, held together by kana.
Al Imran 3:103
فَأَصْبَحْتُم بِنِعْمَتِهِ إِخْوَانًا
“And by His favour you became brothers.”
Sister: asbaha. Ism: the attached ta of أَصْبَحْتُم (you). Khabar: إِخْوَانًا, a broken plural in the accusative. Contrast with sound and broken plurals if that word stops you.
An-Nahl 16:58
ظَلَّ وَجْهُهُ مُسْوَدًّا
“His face remains dark.”
Sister: zalla. Ism: وَجْهُهُ. Khabar: مُسْوَدًّا. The ayah describes the attitude of the Jahiliyyah toward the birth of a daughter, which the Quran condemns.
Maryam 19:31
مَا دُمْتُ حَيًّا
“For as long as I live.”
Sister: ma dama. Ism: the ta of دُمْتُ (I). Khabar: حَيًّا. The sense of duration is the whole point of this verb.
Ta-Ha 20:91
لَن نَّبْرَحَ عَلَيْهِ عَاكِفِينَ
“We will not cease to remain devoted to it.”
Here the continuity sister is نَبْرَحَ from bariha, with lan in front. Khabar: عَاكِفِينَ, a sound masculine plural, whose accusative ending is -ina.
Ash-Shura 42:11
لَيْسَ كَمِثْلِهِ شَيْءٌ
“There is nothing like Him.”
Khabar first: كَمِثْلِهِ. Ism last: شَيْءٌ, still with its damma. The word order flips but the endings tell the story.
Al-Baqarah 2:177
لَيْسَ الْبِرَّ أَن تُوَلُّوا وُجُوهَكُمْ
“Righteousness is not that you turn your faces…”
Here the khabar of laysa is الْبِرَّ with a fatha, and the clause that begins with أَن تُوَلُّوا does the work of the ism. The fatha on the khabar is the clearest sign you are inside this chapter.
At-Tin 95:8
أَلَيْسَ اللَّهُ بِأَحْكَمِ الْحَاكِمِينَ
“Is not Allah the most just of judges?”
Ism of laysa: اللَّهُ. The khabar is بِأَحْكَمِ الْحَاكِمِينَ, with the preposition bi in front, so it shows a kasra but still sits in the khabar slot.
Notice what the pattern does for your reading. Once you spot kana, you stop translating word by word and start translating slots: this is the subject, this is what is said about it, and this is the time frame. That is the shift from decoding to understanding.
A 60-Second Exercise
Open any surah you know well and scan the first page for kana, a past form such as كَانُوا (kanu, they were), or لَيْسَ. For each one, find the ism and the khabar. Say the khabar out loud and check that it carries a fatha. Two or three finds is enough, and you will find them quickly.

Frequently Asked Questions
What is the rule for kana and its sisters in Arabic?
Kana and its sisters enter a nominal sentence, keep the first word raised as their ism, and put the second word in the accusative as their khabar. For example, the door is open becomes kana al-babu maftuhan.
How many sisters does kana have?
The traditional count is thirteen verbs, including kana itself: asbaha, amsa, adha, zalla, bata, sara, laysa, ma zala, ma infakka, ma fati'a, ma bariha and ma dama.
Does kana always mean was?
No. Kana carries a sense of time, but with the Names of Allah, as in 4:17, it is usually translated as ever, because it does not confine the attribute to the past. In its present form, yakunu, it covers is and will be.
Is laysa the same as la?
No. Laysa is a verb in the kana family, so it takes an ism and a khabar with kana's endings. La is a particle that negates without changing the endings of the words after it.
What is the difference between kana and inna?
Kana puts its second word in the accusative and leaves the first word raised. Inna does the reverse: it puts the first word in the accusative and leaves the second raised.
