The Accusative Case (Nasb)

Introduction

In L2.04, you mastered when nouns take nominative case — the “doer” and “topic” case for subjects and predicates. Now we turn to the second of Arabic’s three cases: the accusative case. This is the “receiver” case, marking nouns that receive actions or describe circumstances.

Notice that this verse contains an imperative verb قُلْ (qul) “say.” While verbs don’t take case themselves, the words around them DO — and the accusative case plays a crucial role in marking direct objects and other functions. In this lesson, you’ll master when and why Arabic nouns shift to accusative case.

In this lesson, you will:

• Understand when and why nouns take the accusative case (naṣb / نَصْبٌ)
• Recognize accusative markers across different noun forms: singular, dual, and plural
• Identify direct objects, circumstantial expressions, and other accusative functions
• Apply the i’rab analysis format to accusative constructions

Connection to previous learning: You now know nominative marks subjects (fāʿil) and topics (mubtadaʾ). Accusative marks the OPPOSITE role: objects that RECEIVE action rather than perform it. Together, these two cases handle the core relationships in Arabic sentences.

Key progression: Nominative (L2.04) → Accusative (L2.05) → Genitive (L2.06). Master all three cases, and you’ll unlock the grammatical structure of every Quranic verse.

Understanding the Accusative Case

Plain English first: The accusative case is the “receiver” case. It marks nouns that are receiving an action (direct objects), describing circumstances (time, place, manner), or being affected by special particles. Think of accusative as the “what happened to it?” case — it answers questions like “What did you do?” or “When did it happen?”

English analogy: English has accusative case remnants in pronouns. We say “I saw HIM” (not “I saw HE”) and “She helped ME” (not “She helped I”). The words “him” and “me” are accusative forms — they receive the action. Arabic extends this principle to ALL nouns using vowel markers.

In the sentence “I read the book,” the book is receiving the action of reading. In Arabic, “the book” would take accusative case to show this receiver role.

Now the Arabic terminology: The accusative case (naṣb / نَصْبٌ) — literally meaning “setting up” or “positioning” — is marked by specific endings that vary based on the noun’s form.

Accusative Markers by Noun Type

Key insight: Compare these to nominative markers (damma ـُ / ـٌ). Nominative uses the “u” sound (damma), while accusative uses the “a” sound (fatha). This vowel shift signals the grammatical function change from doer to receiver.

Important contrast:

• Nominative: ٱلرَّجُلُ (ar-rajulu) — the man [as subject]
• Accusative: ٱلرَّجُلَ (ar-rajula) — the man [as object]

The ONLY difference is the final vowel, but it completely changes the grammatical role.

The Main Functions That Take Accusative Case

There are several grammatical functions that trigger accusative case. We’ll focus on the FOUR most common ones you’ll encounter in the Quran.

Function 1: Direct Object (Maf’ul Bih)

The direct object (mafʿūl bih / مَفْعُولٌ بِهِ) is the noun receiving the action of a verb. It ALWAYS takes accusative case.

Pattern: Verb + Subject (nominative) + Object (accusative)

Example structure:

• قَرَأَ ٱلطَّالِبُ ٱلْكِتَابَ (qaraʾa ṭ-ṭālibu l-kitāba) — “The student read the book”
  • قَرَأَ (qaraʾa): verb “read”
  • ٱلطَّالِبُ (aṭ-ṭālibu): subject (fāʿil) in nominative with damma
  • ٱلْكِتَابَ (al-kitāba): direct object in accusative with fatha

The principle: The subject DOES the action (nominative). The object RECEIVES the action (accusative). This is the fundamental subject-object relationship in Arabic grammar.

Function 2: Circumstantial Expressions (Haal)

The circumstantial accusative (ḥāl / حَالٌ۬) describes the state, manner, or circumstances of an action. These expressions answer questions like “How?” “When?” or “In what condition?”

Examples:

• Time: يَوْمًا (yawman) — “for a day”
• Manner: صَفًّا صَفًّا (ṣaffan ṣaffan) — “row upon row”
• State: وَحِيدًا۟ (waḥīdan) — “alone”

Pattern: The ḥāl noun takes accusative (usually fathatain ـً for indefinite) to show it’s describing circumstances rather than being the main subject or object.

Function 3: Subject of Inna (Ism Inna)

The particle إِنَّ (inna) “indeed/verily” is special — it CHANGES the normal nominative case of a subject to accusative.

Normal nominal sentence:

• ٱللَّهُ رَحِيمٌ (allāhu raḥīmun) — “Allah is Merciful”
  • ٱللَّهُ (allāhu): subject (mubtadaʾ) in nominative

With إِنَّ particle:

• إِنَّ ٱللَّهَ رَحِيمٌ (inna llāha raḥīmun) — “Indeed, Allah is Merciful”
  • ٱللَّهَ (allāha): subject (ism inna) NOW in accusative with fatha

Why this matters: إِنَّ and its sisters (you’ll study in L2.10) are among the few particles powerful enough to override normal case rules. Recognizing when a subject shifts to accusative helps you identify these emphasis particles.

Function 4: Predicate of Kaana (Khabar Kaana)

The verb كَانَ۟ (kāna) “was/is” also modifies normal case rules, but in the opposite direction from إِنَّ. It changes the PREDICATE from nominative to accusative.

Normal nominal sentence:

• ٱلرَّجُلُ كَرِيمٌ (ar-rajulu karīmun) — “The man is generous”
  • كَرِيمٌ۬ (karīmun): predicate in nominative

With كَانَ۟ verb:

• كَانَ۟ ٱلرَّجُلُ كَرِيمًا۟ (kāna r-rajulu karīman) — “The man was generous”
  • ٱلرَّجُلُ (ar-rajulu): subject (ism kāna) stays nominative
  • كَرِيمًا (karīman): predicate (khabar kāna) NOW in accusative

You’ll master كَانَ and its sisters in L2.11. For now, recognize that some verbs and particles have the special power to change expected case patterns.

Examples from the Quran

Let’s examine clear examples of accusative case (naṣb) in action — nouns that carry fatha or fathatain because they function as direct objects, subjects of إِنَّ, or other accusative roles.

Example 1: Direct Object (Maf’ul Bih)

Grammatical analysis (iʿrāb):

• خَلَقَ (khalaqa) — Past tense verb — “He created”

  • Function: Past tense transitive verb
  • Hidden subject: هُوَ (He) — Allah

• ٱلْإِنسَٰنَ (al-insāna) — Accusative — “mankind”

  • Function: Direct object (mafʿūl bih / مَفْعُولٌ بِهِ)
  • Case marker: Accusative with fatha (ـَ)
  • Reason: Receives the action of the verb خَلَقَ — “created WHAT? mankind”

• مِنْ عَلَقٍ (min ʿalaqin) — Prepositional phrase

  • مِنْ: Preposition “from”
  • عَلَقٍ: Genitive with kasratain (ـٍ) — after preposition

Key point: ٱلْإِنسَٰنَ is accusative because it’s the direct object. The fatha (ـَ) on the ن is the accusative marker.

Example 2: Subject of إِنَّ (Ism of Inna)

Grammatical analysis (iʿrāb):

• إِنَّ (inna) — Emphatic particle — “indeed”

  • Function: Makes the following noun accusative

• ٱللَّهَ (allāha) — Accusative — “Allah”

  • Function: Subject of إِنَّ (ism inna / اسم إنَّ)
  • Case marker: Accusative with fatha (ـَ)
  • Reason: إِنَّ forces its subject into accusative case

• غَفُورٌۭ (ghafūrun) — Nominative — “Forgiving”

  • Function: Predicate of إِنَّ (khabar inna)
  • Case marker: Nominative with dammatain (ـٌ)

Key point: Even though ٱللَّهَ is the SUBJECT of the sentence, إِنَّ forces it into accusative. Compare: ٱللَّهُ غَفُورٌ (nominative, no إِنَّ) vs. إِنَّ ٱللَّهَ غَفُورٌ (accusative, with إِنَّ).

Example 3: Indefinite Accusative (Tanwin Fatha)

Grammatical analysis (iʿrāb):

• رَأَيْتَ (raʾayta) — Past tense verb — “you saw/see”

  • Function: Transitive verb taking a direct object

• ٱلنَّاسَ (an-nāsa) — Accusative — “the people”

  • Function: Direct object of رَأَيْتَ
  • Case marker: Accusative with fatha (ـَ)
  • Reason: Receives the action of seeing

• أَفْوَاجًۭا (afwājan) — Accusative — “in multitudes”

  • Function: Ḥāl (state/condition) describing HOW the people enter
  • Case marker: Accusative with fathatain (ـًا)
  • Reason: Ḥāl is always accusative and indefinite

Two accusatives in one verse: ٱلنَّاسَ (direct object) and أَفْوَاجًۭا (ḥāl). Both carry fatha — one as a definite noun (fatha only) and one as indefinite (fathatain).

Example 4: Accusative After كَانَ

Grammatical analysis (iʿrāb):

• كَانَ (kāna) — Incomplete verb — “was/is”

  • Function: Changes the predicate of a nominal sentence to accusative

• ٱللَّهُ (allāhu) — Nominative — “Allah”

  • Function: Subject of كَانَ (ism kāna)
  • Case marker: Nominative with damma (ـُ)

• غَفُورًۭا (ghafūran) — Accusative — “Forgiving”

  • Function: Predicate of كَانَ (khabar kāna)
  • Case marker: Accusative with fathatain (ـًا)
  • Reason: كَانَ forces its predicate into accusative

Key contrast with Example 2:

• إِنَّ ٱللَّهَ غَفُورٌ — إِنَّ makes the subject accusative, predicate stays nominative
• كَانَ ٱللَّهُ غَفُورًا — كَانَ makes the predicate accusative, subject stays nominative

Example 5: Direct Object — Visible Fatha

Grammatical analysis (iʿrāb):

• وَدَّعَ (waddaʿa) — Past tense verb — “abandoned/took leave”

• كَ (-ka) — Accusative pronoun suffix — “you”

  • Function: Direct object (attached pronoun in accusative position)
  • The pronoun كَ is always in the accusative when attached as an object
  • Meaning: “abandoned YOU” — the “you” receives the action

• رَبُّكَ (rabbuka) — Nominative — “your Lord”

  • Function: Subject (fāʿil) of the verb وَدَّعَ
  • Case marker: Nominative with damma (ـُ)

Teaching moment: Attached pronouns like كَ (you), هُ (him), هَا (her) are always accusative when they’re objects. They don’t show visible case markers — you know their case from their grammatical function.

The Rule

Practice

جَاءَ۟    [verb - no case]
رَسُولُ  [subject → NOM]
ٱللَّهِ  [possession → GEN]
يَوْمًا  [time circumstance → ACC]
