Badal: Definition, Four Types, and Parsing

1. Definition of Badal

فَصْلٌ: الْبَدَلُ: تَابِعٌ يُنْسَبُ إِلَيْهِ مَا نُسِبَ إِلَى مَتْبُوعِهِ، وَهُوَ الْمَقْصُودُ بِالنِّسْبَةِ دُونَ مَتْبُوعِهِ.
Translation: Badal is a grammatical follower to which the same predication is directed as to its preceding term; the badal is the primary intended referent rather than the preceding term.

A follower takes the case of the preceding word. The phrase intended by the predication identifies the badal as the primary focus of the assertion.

2. What Is the Main Intended Referent?

جَاءَنِي زَيْدٌ أَخُوكَ — Zayd, your brother, came to me.
The coming is attributed to the same individual. Zayd is mentioned first, and your brother supplies the intended appositional identity.

This does not add a second visitor. It re-identifies the single person.

3. The Four Types of Badal

وَأَقْسَامُ الْبَدَلِ أَرْبَعَةٌ:
Translation: The types of badal are four.

The four kinds are whole-for-whole, part-for-whole, inclusion/association, and slip-of-the-tongue correction. All are followers but differ in the relation to their antecedent.

4. Badal Versus Other Followers

Adjective: "the learned Zayd" describes a quality.
Emphasis: "Zayd himself" reinforces identity.
Badal: "Zayd—your brother" identifies the person primarily intended.

All follow a nominative in these examples, but their semantic jobs differ. The first two are teaching comparisons.

5. Whole-for-Whole Badal

بَدَلُ الْكُلِّ مِنَ الْكُلِّ: وَهُوَ مَا مَدْلُولُهُ مَدْلُولُ الْمَتْبُوعِ، نَحْوُ: «جَاءَنِي زَيْدٌ أَخُوكَ».
Translation: Whole-for-whole badal denotes the very same referent as its antecedent, as in: Zayd, your brother, came to me.

Zayd and your brother point to one person. "Whole" does not mean an entire population; it means coextensive reference here.

6. Full Parsing: Zayd, Your Brother

جَاءَنِي زَيْدٌ أَخُوكَ — Zayd, your brother, came to me.
جَاءَ: past verb built on fatḥah.
نِي: attached accusative object pronoun; n is nūn al-wiqāyah.
زَيْدٌ: nominative subject with ḍammah.
أَخُوكَ: whole-for-whole badal, nominative with wāw because akhū is one of the six nouns; it is mudāf, while -ka is mudāf ilayh.

The case is the same (nominative) although Zayd has ḍammah and akhū has wāw.

7. Two Labels, One Person

The base clause jāʾanī Zaydun is complete. Adding akhūka identifies the intended Zayd.

To report two distinct visitors one would generally use a coordinated expression such as “Zayd and your brother.” That is not the meaning of the book’s badal example.

8. Whole-for-Whole Badal in Accusative

Additional teaching example: رَأَيْتُ زَيْدًا أَخَاكَ — I saw Zayd, your brother.
رَأَيْتُ: past verb with attached first-person subject.
زَيْدًا: accusative direct object by fatḥah.
أَخَاكَ: accusative whole-for-whole badal with alif (six-noun rule); -ka is genitive mudāf ilayh.

Additional teaching example. Akhāka does not introduce a second separate object; it refers to Zayd.

9. Whole-for-Whole Badal in Genitive

Additional teaching example: مَرَرْتُ بِزَيْدٍ أَخِيكَ — I passed by Zayd, your brother.
مَرَرْتُ: past verb with subject suffix.
بِزَيْدٍ: preposition bāʾ and genitive noun Zayd.
أَخِيكَ: genitive badal with yāʾ as a six-noun form; mudāf to -ka.

Additional teaching example: the badal follows nominative, accusative or genitive case, even if its visible sign differs.

10. Part-for-Whole Badal

وَبَدَلُ الْبَعْضِ مِنَ الْكُلِّ: وَهُوَ مَا مَدْلُولُهُ جُزْءُ مَدْلُولِ الْمَتْبُوعِ، نَحْوُ: «ضَرَبْتُ زَيْدًا رَأْسَهُ».
Translation: Part-for-whole badal denotes a component of the antecedent, as in: I struck Zayd—his head.

The head is an actual part of Zayd. The attached pronoun -hu links the part back to its antecedent.

11. Full Parsing: I Struck His Head

ضَرَبْتُ زَيْدًا رَأْسَهُ — I struck Zayd’s head.
ضَرَبْتُ: past verb with subject -tu.
زَيْدًا: accusative object, antecedent.
رَأْسَهُ: part-for-whole badal, accusative with fatḥah; raʾs is mudāf and -hu mudāf ilayh.
-hu: pronoun referring back to Zayd.

The book parses raʾsahu as badal, not as an independent second object of ḍaraba.

12. What Makes Something a Part?

Part-for-whole badal points to an actual component: a head within a person, or half of a book.

قَرَأْتُ الْكِتَابَ نِصْفَهُ — I read the book, namely half of it. Niṣfahu is part-for-whole badal.

This is an additional teaching example; -hu refers to al-kitāb.

13. Parsing Half of the Book

Additional teaching example: قَرَأْتُ الْكِتَابَ نِصْفَهُ — I read half of the book.
قَرَأْتُ: past verb; -tu is subject.
الْكِتَابَ: accusative direct object and antecedent.
نِصْفَهُ: accusative part-for-whole badal; niṣf is mudāf and -hu genitive attached pronoun.

This additional example shows that the badal restricts the intended scope to a part of the book.

14. Why the Attached Pronoun Matters

In raʾsahu, -hu refers to Zayd; in niṣfahu, it refers to the book.

The pronoun is the link back to the whole. Without the link, the part-to-whole relation may be unclear.

15. Badal of Association (Ishtimāl)

وَبَدَلُ الِاشْتِمَالِ: وَهُوَ مَا مَدْلُولُهُ مُتَعَلِّقُ الْمَتْبُوعِ، نَحْوُ: «سُلِبَ زَيْدٌ ثَوْبُهُ».
Translation: Badal of ishtimāl denotes something associated with the antecedent; for example, Zayd was robbed of his garment.

The author says related to the antecedent, not part of the antecedent. Clothing is associated with Zayd but is not a bodily part. That is the core distinction from part-for-whole badal.

16. Full Parsing: Zayd and His Garment

سُلِبَ زَيْدٌ ثَوْبُهُ — Zayd had his garment taken away.
سُلِبَ: past passive verb.
زَيْدٌ: nominative passive subject (nāʾib fāʿil), antecedent.
ثَوْبُهُ: nominative badal al-ishtimāl in the book’s analysis; thawb is mudāf and -hu is mudāf ilayh.
-hu: pronoun referring to Zayd.

This is the source’s intended analysis: thawbuhu is badal of association, not a bodily component.

17. Associated Does Not Mean a Physical Part

Raʾsuhu: the head is a component of the person — part-for-whole.
Thawbuhu: the garment belongs to or is associated with the person, not a bodily part — ishtimāl.

An attached -hu is not enough by itself to identify the type. Ask what kind of relation it expresses.

18. Knowledge: Another Ishtimāl Example

أَعْجَبَنِي زَيْدٌ عِلْمُهُ — Zayd impressed me—his knowledge did.
أَعْجَبَ: past verb; -nī is its object.
زَيْدٌ: nominative subject and antecedent.
عِلْمُهُ: nominative badal al-ishtimāl; ʿilm is mudāf and -hu mudāf ilayh.

The book’s marginal commentary gives this explanatory example. Knowledge is associated with Zayd, not a physical part of him.

19. Two Questions to Classify Badal

Ask: Is it an actual component? If yes, think part-for-whole (head, half).
If not, ask Is it associated with the antecedent? Then ishtimāl may apply (garment, knowledge).

This is a teaching diagnostic; verify the sentence’s case and context too.

20. Badal After a Slip of the Tongue

وَبَدَلُ الْغَلَطِ: وَهُوَ مَا ذُكِرَ بَعْدَ الْغَلَطِ، نَحْوُ: «جَاءَنِي زَيْدٌ جَعْفَرٌ»، أَوْ «رَأَيْتُ رَجُلًا حِمَارًا».
Translation: Badal of error is what is mentioned after an inadvertent mistaken word: “Zayd—rather, Jaʿfar—came to me,” or “I saw a man—rather, a donkey.”

Here ghalaṭ means a speech slip. The first word was said accidentally; the second is the intended correction. It is not a claim of shared identity or species.

21. Parsing the Corrected Name

جَاءَنِي زَيْدٌ جَعْفَرٌ — Zayd—rather, Jaʿfar—came to me.
جَاءَ: past verb.
نِي: attached object with protective nūn.
زَيْدٌ: initially uttered nominative subject and antecedent.
جَعْفَرٌ: nominative badal of correction; Jaʿfar is the intended visitor.

This is a constructed grammatical example, not a report about an actual event.

22. Parsing a Corrected Object

رَأَيْتُ رَجُلًا حِمَارًا — I saw a man—rather, a donkey.
رَأَيْتُ: past verb with -tu as subject.
رَجُلًا: initially uttered accusative object, the antecedent.
حِمَارًا: accusative badal of correction; this is the intended object.

The example illustrates correcting a mistaken word, not describing a person as an animal.

23. Correction Versus Re-Identification

Zaydun akhūka: the second phrase re-identifies the same person — whole-for-whole.
Zaydun Jaʿfarun: the second name repairs a slip of the tongue — error-correction badal.

Both second nouns are nominative; the speaker’s intention distinguishes them.

24. An Indefinite Badal Following a Definite Antecedent

وَالْبَدَلُ إِنْ كَانَ نَكِرَةً مِنْ مَعْرِفَةٍ، يَجِبُ نَعْتُهُ، كَقَوْلِهِ تَعَالَى: ﴿بِالنَّاصِيَةِ نَاصِيَةٍ كَاذِبَةٍ﴾.
Translation: If the badal is indefinite while the antecedent is definite, the text requires it to be described by an adjective; as in the Qur’anic phrase: “by the forelock—a lying forelock.”

The source cites an excerpt from Qurʾān 96:15–16, not the complete verses. Al-nāṣiyah is definite, nāṣiyatin is the indefinite badal, and kādhibatin its adjective.

25. Full Parsing: A Lying Forelock

بِالنَّاصِيَةِ نَاصِيَةٍ كَاذِبَةٍ — By the forelock—a lying forelock.
بِـ: preposition.
النَّاصِيَةِ: genitive definite antecedent.
نَاصِيَةٍ: genitive indefinite badal with tanwīn.
كَاذِبَةٍ: genitive adjective of nāṣiyatin; it is not another badal.

The three share genitive case but have three distinct functions: antecedent, badal and adjective.

26. Why the Descriptive Word Matters

The book’s special rule concerns an indefinite badal after a definite antecedent. The indefinite noun nāṣiyatin takes the description kādhibatin.

The adjective follows its noun in genitive case and feminine gender.

Not all badal constructions require an adjective; the condition is specific.

27. Limits of the Adjective Requirement

وَلَا يَجِبُ ذَلِكَ فِي عَكْسِهِ، وَلَا فِي الْمُتَجَانِسَيْنِ.
Translation: The adjective is not obligatory in the reverse case or when the two terms belong to the same definiteness class.

Reverse: an indefinite antecedent followed by a definite badal.
Same class: both definite or both indefinite.

The source limits the requirement; do not extend it to every badal.

28. Badal Follows Case, Not Necessarily the Same Sign

Zaydun akhūka: nominative antecedent and nominative badal with wāw.
Zaydan akhāka: accusative antecedent and badal with alif.
bi-Zaydin akhīka: genitive antecedent and badal with yāʾ.

Badal follows grammatical case, not necessarily the same visible ending. The latter two are teaching examples.

29. Four Types: A Practical Comparison

1. Whole-for-whole: same referent — Zayd / your brother.
2. Part-for-whole: an actual component — his head.
3. Association: related item — his garment.
4. Correction: an unintended first expression replaced by the intended one.

This is a comparison summary; the full source examples have been parsed separately.

30. Badal or Emphasis?

Zaydun nafsuhu: nafsuhu is emphasis; Zayd himself came.
Zaydun akhūka: akhūka is badal; the intended Zayd is your brother.

Both are nominative but perform different discourse functions. This is an additional comparison.

31. Badal or Adjective?

Zaydun al-ʿālimu: al-ʿālimu describes Zayd as an adjective.
Zaydun akhūka: akhūka is the intended badal.

In bi-l-nāṣiyati nāṣiyatin kādhibatin, both functions appear together: nāṣiyatin is badal, kādhibatin is its adjective.

32. Complete Chapter Recap

Badal: a case-following term primarily intended by the attribution.
Four types: whole, part, association and error correction.
Part: literal component, commonly linked by a pronoun.
Association: something related but not a literal component.
Correction: an inadvertent expression is replaced with the intended expression.
Indefinite after definite: the text requires an adjective but exempts the reverse and same-definiteness cases.
