Negation in Arabic: لا, ما, لم, لن, ليس and لا لنفي الجنس

Negation in Arabic is an essential topic for anyone who wants to learn Arabic, understand Arabic grammar and build correct sentences. Unlike English, where negation is often expressed with “not” or auxiliary verbs, Arabic uses several negation particles depending on tense, sentence type and intended meaning.

In this complete lesson, we will study the main particles used to negate an action or a sentence in Arabic: لا, ما, لَمْ, لَنْ and لَيْسَ. We will also study a very important structure in Quranic Arabic: لَا لِنَفِي الجِنْسِ, the لا used to express absolute negation.

This rule is important for beginners, but also for students who want to improve in literary Arabic, Modern Standard Arabic or Quranic Arabic.

What is negation in Arabic?

Negation is used to say that an action does not happen, did not happen or will not happen. It can also be used to negate a nominal sentence, meaning a sentence built around a noun, adjective or description without an apparent verb.

In Arabic, the negation particle is generally placed before the verb or before the element being negated. The choice of particle mainly depends on tense and sentence type:

• present: current or habitual action;
• past: completed or uncompleted past action;
• future: action that will not take place;
• nominal sentence: sentence built around a noun, adjective or description;
• absolute negation: total exclusion of a category or kind.

The main Arabic negation particles

Here are the most important particles to know:

• لا: used to negate a present action;
• ما: used to negate an action, especially in the past, and sometimes in the present depending on context;
• لَمْ: used with the present verb to express past negation;
• لَنْ: used to negate a future action;
• لَيْسَ: used to negate a nominal sentence;
• لَا لِنَفِي الجِنْسِ: used to express absolute negation.

Reminder: the present verb in Arabic

Before studying negation, it is useful to remember that the Arabic present verb can express an ongoing action, a habit or sometimes a future action depending on context.

يَكْتُبُ الآنَ
He is writing now.

With the prefix سـ, the present verb can express the future:

سَيَكْتُبُ غَدًا
He will write tomorrow.

Negation therefore depends on the intended meaning: do we want to say “he is not writing now”, “he did not write” or “he will not write”?

Negating a present action with لا

The particle لا is used to negate a present action. It is placed directly before the verb.

أَنَا لا أُحِبُّ عَصِيرَ الجَوَافَةِ
I do not like guava juice.

نَحْنُ لا نَكْتُبُ عِنْدَمَا يَتَكَلَّمُ الأُسْتَاذُ
We do not write when the teacher speaks.

فَهُوَ لا يُحِبُّ السَّفَرَ دَائِمًا
He does not always like traveling.

With لا, the verb generally remains in the present. This particle is very common in simple sentences studied by beginners.

Using ما to negate an action

The particle ما can be used to negate an action. It is very common with past verbs, but it can also be used with present verbs depending on context and register.

ما with the present verb

In some contexts, ما can have a meaning close to لا with a present verb.

أَنَا ما أُحِبُّ عَصِيرَ الجَوَافَةِ
I do not like guava juice.

نَحْنُ ما نَكْتُبُ عِنْدَمَا يَتَكَلَّمُ الأُسْتَاذُ
We do not write when the teacher speaks.

For beginners, it is better to first remember that لا is the most common particle used to negate the present in standard Arabic grammar.

ما with the past verb

The particle ما is also used to negate a past action. It is placed before the past verb.

ما كَتَبْتُ وَاجِبِي أَمْسِ
I did not write my homework yesterday.

ما اِسْتَيْقَظَ أَبِي مُبَكِّرًا؛ لِأَنَّهُ ما نَامَ مُبَكِّرًا
My father did not wake up early because he had not slept early.

This particle is useful for understanding narrative sentences, dialogues and many Arabic texts.

Negating a past action with لَمْ

The particle لَمْ is very important in Arabic grammar. It is placed before a present verb, but it gives the sentence a past meaning.

وَهُوَ لَمْ يُسَافِرْ إِلَى أَيِّ بَلَدٍ مِنْ قَبْلُ
He has never traveled to any country before.

Remember this rule clearly: even if the Arabic verb appears in a present form, the particle لَمْ gives the sentence a past meaning.

With لَمْ, the following verb generally takes a grammatical form called the jussive. In vocalized examples, this is often seen through a final sukūn.

Negating a future action with لَنْ

The particle لَنْ is used to negate a future action. It often corresponds to “will not” in English.

أَخِي لَنْ يُسَافِرَ مَعَنَا غَدًا
My brother will not travel with us tomorrow.

لَنْ أَرْجِعَ إِلَى بَلَدِي
I will not return to my country.

لَنْ يَدْرُسَ
He will not study.

With لَنْ, the following verb takes a grammatical form called the subjunctive in Arabic grammar. In simple vocalized examples, this is often seen through the final vowel َ.

Using لَيْسَ to negate a nominal sentence

The particle لَيْسَ is different from the others because it is not mainly used to negate an action verb. It is used to negate a nominal sentence, meaning a sentence that does not begin with a verb.

لَيْسَ البَحْرُ أَكْبَرَ مِنَ المُحِيطِ
The sea is not bigger than the ocean.

وَلَيْسَتِ البُحَيْرَةُ أَكْبَرَ مِنَ البَحْرِ
And the lake is not bigger than the sea.

لَيْسَ agrees with the subject. You can therefore find different forms according to gender and number.

Absolute negation with لَا لِنَفِي الجِنْسِ

In Arabic, there is a specific use of لا called لَا لِنَفِي الجِنْسِ. This structure is used to express total or absolute negation. It denies the existence of an entire category within the context of the sentence.

The best-known example is:

لَا إِلَهَ إِلَّا اللَّهُ

There is no deity except Allah. (37:35)

In this sentence, the negation is not an ordinary simple negation. It means that there is no deity worthy of worship except Allah.

Rules of لَا لِنَفِي الجِنْسِ

The structure لَا لِنَفِي الجِنْسِ follows several important rules:

1. It expresses total or absolute negation.
2. It negates an entire kind or category in the context of the sentence.
3. The noun that follows لا does not take tanwīn.
4. The noun that follows لا is generally in the accusative.
5. The predicate of the sentence generally remains nominative.

Example:

لَا إِلَهَ إِلَّا هُوَ

There is no deity except Him. (2:163)

In this sentence, إِلَهَ is the noun that follows لا. It does not take tanwīn and is marked with fatḥah.

Another example of لَا لِنَفِي الجِنْسِ

ذَلِكَ الْكِتَابُ لَا رَيْبَ فِيهِ

This is the Book about which there is no doubt. (2:2)

Here, لَا رَيْبَ means “there is no doubt at all”. The word رَيْبَ does not take tanwīn and is marked with fatḥah.

Quranic examples of absolute negation

The structure لَا لِنَفِي الجِنْسِ appears in several passages of the Quran. It expresses strong and complete negation.

لَا خَلَاقَ

أُولَئِكَ لَا خَلَاقَ لَهُمْ فِي الْآخِرَةِ

Those will have no share in the Hereafter. (3:77)

لَا إِلَهَ

اللَّهُ لَا إِلَهَ إِلَّا هُوَ الْحَيُّ الْقَيُّومُ

Allah! There is no deity except Him, the Ever-Living, the Sustainer. (2:255)

لَا رَفَثَ وَلَا فُسُوقَ وَلَا جِدَالَ

فَرَضَ فِيهِنَّ الْحَجَّ فَلَا رَفَثَ وَلَا فُسُوقَ وَلَا جِدَالَ فِي الْحَجِّ

If one undertakes Hajj, then there should be no intimate relations, no disobedience and no dispute during Hajj. (2:197)

لَا جُنَاحَ

لَا جُنَاحَ عَلَيْكُمْ

There is no sin upon you. (2:236)

لَا عِلْمَ

لَا عِلْمَ لَنَا إِلَّا مَا عَلَّمْتَنَا

We have no knowledge except what You have taught us. (2:32)

وَلَا أَصْغَرَ وَلَا أَكْبَرَ

وَلَا أَصْغَرَ مِنْ ذَلِكَ وَلَا أَكْبَرَ إِلَّا فِي كِتَابٍ مُبِينٍ

Nor anything smaller than that nor greater, except that it is in a clear Book. (10:61)

Difference between simple لا and لَا لِنَفِي الجِنْسِ

Do not confuse لا used to negate a present verb with لا used to negate an entire category.
