Conjugating the Prohibitive with Heavy Noon (Active & Passive)

1. Heavy Noon in the Prohibitive

Heavy Noon makes the prohibition stronger. Compare: لَا تَفْعِلْ → لَا تَفْعِلَنَّ.
This level keeps the active generic paradigm on one consistent pattern: يَفْعِلُ. The middle root letter therefore keeps Kasrah throughout the active conjugation; only the endings change according to the Heavy-Noon rules.

2. Active Haadhir: Six Forms with Heavy Noon

The six active Haadhir forms remain on the same Kasrah pattern.

FormPosition
لَا تَفْعِلَنَّsingular masculine Haadhir
لَا تَفْعِلَانِّdual masculine Haadhir
لَا تَفْعِلُنَّplural masculine Haadhir
لَا تَفْعِلِنَّsingular feminine Haadhir
لَا تَفْعِلَانِّdual feminine Haadhir
لَا تَفْعِلْنَانِّplural feminine Haadhir

Check: every active form still keeps Kasrah on the middle root letter.

3. Four Ending Patterns to Recognize

Heavy Noon changes the ending in predictable ways without changing the chosen active pattern.

ExampleWhat to notice
لَا تَفْعِلَنَّFathah immediately before Heavy Noon
لَا تَفْعِلَانِّAlif before Heavy Noon; Heavy Noon carries Kasrah
لَا تَفْعِلُنَّDhammah before Heavy Noon in masculine plural
لَا تَفْعِلِنَّKasrah before Heavy Noon in singular feminine Haadhir

Feminine plural uses Alif-e-Faasil: لَا تَفْعِلْنَانِّ.

4. Active Ghaa'ib and Mutakallim: Eight More Forms

The remaining active forms also stay on the same Kasrah pattern.

FormPosition
لَا يَفْعِلَنَّsingular masculine Ghaa'ib
لَا يَفْعِلَانِّdual masculine Ghaa'ib
لَا يَفْعِلُنَّplural masculine Ghaa'ib
لَا تَفْعِلَنَّsingular feminine Ghaa'ib
لَا تَفْعِلَانِّdual feminine Ghaa'ib
لَا يَفْعِلْنَانِّplural feminine Ghaa'ib
لَا أَفْعِلَنَّMutakallim singular
لَا نَفْعِلَنَّMutakallim plural

The generic active table does not mix Kasrah and Dhammah patterns.

5. Complete Passive Prohibitive with Heavy Noon

The passive paradigm follows its own consistent passive pattern: the Mudhaari' prefix carries Dhammah and the middle root letter carries Fathah.

6. Active and Passive: Same Seegah, Different Vowels

The Heavy-Noon ending can be the same while the internal vowel pattern tells you the voice.

PassiveActivePosition
لَا يُفْعَلَنَّلَا يَفْعِلَنَّsingular masculine Ghaa'ib
لَا تُفْعَلَنَّلَا تَفْعِلَنَّsingular masculine Haadhir
لَا أُفْعَلَنَّلَا أَفْعِلَنَّMutakallim singular

Fast clue: active prefix vowel = Fathah; passive prefix vowel = Dhammah.

7. Practice with Daraba–Yadribu

Use a real verb on the same Kasrah pattern: ضَرَبَ — يَضْرِبُ.

8. A Reliable Reading Strategy

Use this order: 1. Fix the active pattern first. 2. Keep the middle-root vowel consistent. 3. Read the Heavy-Noon ending pattern. 4. Use the Mudhaari' prefix vowel to distinguish active from passive. 5. Read the meaning as emphatic prohibition.
This avoids the main error: mixing two different active patterns in one conjugation.
