Ism of Mā and Lā Resembling Laysa; Khabar of Lā of Generic Negation

1. The Source Heading

فَصْلٌ: اسْمُ مَا وَلَا الْمُشَبَّهَتَيْنِ بِلَيْسَ.
Translation: This section discusses the nouns governed by mā and lā when they resemble laysa in grammatical action.

This is not a rule for every kind of mā or lā; it specifically concerns negative particles working like laysa.

2. The Author’s Definition

هُوَ الْمُسْنَدُ إِلَيْهِ بَعْدَ دُخُولِهِمَا.
Translation: After either particle enters, the noun about which the predicate is stated is its ism.

Musnad ilayh is the entity about which a predicate is asserted. It is not the predicate itself.

3. The Source Examples

نَحْوُ: «مَا زَيْدٌ قَائِمًا، وَلَا رَجُلٌ أَفْضَلَ مِنْكَ».
Translation: For example: Zayd is not standing; and no man is better than you.

In the first example mā, and in the second lā, work like laysa: their ism is nominative and their khabar accusative.

4. The Source Restriction

وَيَخْتَصُّ «لَا» بِالنَّكِرَةِ، وَيَعُمُّ «مَا» بِالْمَعْرِفَةِ وَالنَّكِرَةِ.
Translation: In this construction, lā is restricted to an indefinite ism, whereas mā can govern either a definite or an indefinite ism.

This indefinite-only condition refers specifically to lā resembling laysa. We will contrast it with lā of generic negation later in this lesson.

5. Recall the Baseline: Laysa

لَيْسَ زَيْدٌ قَائِمًا
Translation: Zayd is not standing.
لَيْسَ: incomplete past-form verb expressing negation.
زَيْدٌ: nominative ism of laysa (ḍamma).
قَائِمًا: accusative khabar of laysa (fatḥa).

Here mā and lā are particles, not verbs, but in the specified constructions they govern the same case pattern.

6. Full Parsing: Mā Zaydun Qāʾiman

مَا زَيْدٌ قَائِمًا
Translation: Zayd is not standing.
مَا: negative particle working like laysa; indeclinable.
زَيْدٌ: nominative ism mā, visible ḍamma.
قَائِمًا: accusative khabar mā, visible fatḥa.

The underlying nominal sentence was زَيْدٌ قَائِمٌ. This working mā leaves the ism nominative and changes the predicate to accusative.

7. Compare Three Constructions

زَيْدٌ قَائِمٌ — nominative subject and predicate; positive statement.
لَيْسَ زَيْدٌ قَائِمًا — nominative ism and accusative khabar of laysa.
مَا زَيْدٌ قَائِمًا — nominative ism and accusative khabar of the working mā.

Identify the actual governor before assigning cases; negation alone does not determine case.

8. Full Parsing: Lā Rajulun Afḍala Minka

وَلَا رَجُلٌ أَفْضَلَ مِنْكَ
Translation: And no man is better than you.
وَ: coordinating/resumptive particle.
لَا: negative particle working like laysa.
رَجُلٌ: nominative ism lā; indefinite noun.
أَفْضَلَ: accusative khabar lā; comparative noun/adjective.
مِنْكَ: min is a preposition; -ka is an attached genitive pronoun; phrase complements “better.”

The nominative, nunated رَجُلٌ is crucial; do not confuse it with the built-on-fatḥ رَجُلَ under lā of generic negation.

9. Why Is Afḍala Accusative?

The word أَفْضَلَ is an ism tafḍīl (comparative), but its syntactic role here is the khabar of lā; hence it is accusative.

مِنْكَ answers “better than whom?” It complements the predicate, not the ism.

10. Additional Example: Definite Ism after Mā

مَا الْمُعَلِّمُ غَائِبًا
Translation: The teacher is not absent.
مَا: working negative particle.
الْمُعَلِّمُ: definite, nominative ism mā.
غَائِبًا: accusative khabar mā.

This is an added teaching example, not a quotation from the book. It illustrates why the ism of working mā may be definite.

11. Additional Example: Indefinite Ism after Mā

مَا طَالِبٌ مُهْمِلًا
Translation: No student is negligent.
مَا: negative particle working like laysa.
طَالِبٌ: indefinite nominative ism mā.
مُهْمِلًا: accusative khabar mā.

Compare with the preceding example: mā governs both, although one ism is definite and the other indefinite.

12. Additional Example: Indefinite Ism with Lā

لَا طَالِبٌ غَائِبًا
Translation: No student is absent.
لَا: lā functioning like laysa.
طَالِبٌ: indefinite, nominative ism lā.
غَائِبًا: accusative khabar lā.

This supplementary example has the same pattern as the source’s lā rajulun afḍala minka.

13. Why Lā’s Ism Must Be Indefinite Here

The book restricts the ism of lā acting like laysa to indefinite nouns. Thus لَا زَيْدٌ قَائِمًا is not a valid illustration of this governing pattern.

This does not mean lā can never appear near a proper noun in other constructions. The point is to identify the type of lā and whether it governs.

14. Definite versus Indefinite

زَيْدٌ — definite as a proper name.
الْمُعَلِّمُ — definite because of al-.
رَجُلٌ — indefinite in this form.
طَالِبٌ — indefinite in this form.

The working mā accepts either type; working lā resembling laysa is restricted to an indefinite ism.

15. The Book’s Next Short Heading

فَصْلٌ: خَبَرُ لَا الَّتِي لِنَفْيِ الْجِنْسِ.
Translation: This section treats the khabar of the lā used to negate an entire class.

Keep this lā nāfiya li-l-jins distinct from lā resembling laysa; their case patterns differ.

16. The Source Definition and Example

وَهُوَ الْمُسْنَدُ بَعْدَ دُخُولِهَا، نَحْوُ: «لَا رَجُلَ قَائِمٌ».
Translation: The khabar is what is predicated after this lā enters, as in “No man is standing.”

The book gives a short definition and one example; the explanation of the ism being built on fatḥ in the following slides is additional teaching analysis.

17. Full Parsing: Lā Rajula Qāʾimun

لَا رَجُلَ قَائِمٌ
Translation: No man is standing.
لَا: particle of generic negation, whose ism is accusative in function and whose khabar is nominative.
رَجُلَ: singular indefinite ism lā, built on fatḥ, in the accusative position.
قَائِمٌ: nominative khabar lā, visible ḍamma.

The ism is built on fatḥ; the predicate remains nominative. Compare the earlier pattern in which the predicate was accusative.

18. Two Lā Constructions, Two Case Patterns

لَا رَجُلٌ أَفْضَلَ مِنْكَ — lā resembling laysa: rajulun nominative ism; afḍala accusative khabar.
لَا رَجُلَ قَائِمٌ — generic-negating lā: rajula built on fatḥ in the accusative position; qāʾimun nominative khabar.

Both express negation, but their governing action and case marking differ.

19. Why Rajula Is Built on Fatḥ

With generic-negating lā, a singular ism that is neither muḍāf nor quasi-muḍāf is normally built on the sign it would take in the accusative; here rajula has fatḥ.

It is in the accusative position, but it is not inflected as رَجُلًا with tanwīn.

20. Supplementary: A Prepositional Phrase as Khabar

لَا رَجُلَ فِي الْغُرْفَةِ
Translation: There is no man in the room.
لَا: generic-negating particle.
رَجُلَ: ism lā built on fatḥ, in an accusative position.
فِي: preposition; الْغُرْفَةِ: genitive noun.
فِي الْغُرْفَةِ: prepositional expression relating to an understood predicate (khabar lā).

The predicate need not be an overt single nominative noun; here it is expressed through a prepositional construction.

21. Supplementary: The Muḍāf Ism of Lā

لَا طَالِبَ عِلْمٍ مُهْمِلٌ
Translation: No seeker of knowledge is negligent.
لَا: generic-negating particle.
طَالِبَ: accusative ism lā with visible fatḥ, because it is muḍāf (thus inflected, not built as the non-muḍāf singular).
عِلْمٍ: genitive muḍāf ilayh.
مُهْمِلٌ: nominative khabar lā.

This is an added teaching example to prevent overgeneralizing the rule for the simple, non-construct ism.

22. A Practical Decision Sequence

1. First identify whether the particle is mā or lā.
2. When mā works like laysa, its ism is nominative and khabar accusative.
3. When lā works like laysa, the same cases apply, but its ism is indefinite.
4. With lā of generic negation, the ism follows a different rule and the khabar is nominative.

23. Why Negation Alone Is Not Enough

The same broad negative idea can be expressed by different syntactic constructions.

For example, مَا زَيْدٌ قَائِمًا has an accusative predicate, while لَا رَجُلَ قَائِمٌ has a nominative predicate. Meaning alone cannot replace grammatical analysis.

24. A Note on Non-Working Mā

The book illustrates the working construction مَا زَيْدٌ قَائِمًا. In other attested usage, mā can be non-working, with a nominative predicate as in مَا زَيْدٌ قَائِمٌ.

Do not label that other construction universally ungrammatical. Here we are testing the specific working mā presented by the book.

25. When the Negation Is Broken by Illā

مَا زَيْدٌ إِلَّا قَائِمٌ
Translation: Zayd is only standing.
مَا: negative particle, non-working in this exceptive construction.
زَيْدٌ: nominative mubtadaʾ.
إِلَّا: particle marking exclusivity.
قَائِمٌ: nominative khabar.

This is a supplemental teaching rule, not a quoted line from the book.

26. Three Useful Lā Patterns

لَا رَجُلٌ أَفْضَلَ مِنْكَ — lā like laysa: nominative ism + accusative khabar.
لَا رَجُلَ قَائِمٌ — generic lā: ism built on fatḥ in the accusative position + nominative khabar.
لَا تَكْتُبْ — prohibitive lā, which makes the present verb jussive; not an ism–khabar construction.

The third example is only a contrast; the printed passage treats the first two.

27. Parsing Review: Do Not Mix Categories

مَا زَيْدٌ قَائِمًا — Zaydun: ism of working mā; qāʾiman: its khabar.
لَا طَالِبٌ غَائِبًا — ṭālibun: ism of lā like laysa; ghāʾiban: its khabar.
لَا رَجُلَ قَائِمٌ — rajula: ism of generic lā; qāʾimun: its khabar.

Identify the specific particle use before assigning case and syntactic role.

28. Frequent Mistake: Switching Ism and Khabar

In مَا زَيْدٌ قَائِمًا, Zaydun is not the khabar. It is what the statement is about and is the ism of mā.

Qāʾiman conveys the assertion and is its khabar. The same relationship applies to the source’s lā example.

29. Frequent Mistake: Treating All Lā as the Same

The two forms differ in grammar, not just punctuation: rajulun is nominative under lā like laysa, while rajula is built on fatḥ under generic-negating lā.

Always identify which construction is being used.

30. Level Summary

1. Working mā like laysa: nominative ism, accusative khabar, and either definite or indefinite ism.
2. Working lā like laysa: the same cases, but indefinite ism only.
3. Generic lā: a different ism rule; simple non-construct ism built on fatḥ in the accusative position, khabar nominative.
4. The source’s three key examples are مَا زَيْدٌ قَائِمًا; لَا رَجُلٌ أَفْضَلَ مِنْكَ; and لَا رَجُلَ قَائِمٌ.
