Derived Trilateral (without Hamzah) - Bab 5: Tafaa'ul (Taqatul)

1. Bab Tafaa'ul

Bab Tafaa'ul is the fifth derived triliteral door in the group without Hamzat-ul-Wasl.
Its basic past-tense pattern is تَفَاعَلَ.
Two features identify it quickly: a prefixed تَـ and an Alif between the first and second root letters.
The example in this level is تَقَاتَلَ.

2. Root and Masdar

The original root letters of تَقَاتَلَ are ق، ت، ل.
The prefixed تَـ is added, and an Alif is inserted after the first root letter.
Its verbal noun is تَقَاتُلٌ, with the sense of fighting or engaging one another.

3. Complete Sarf-e-Sagheer

Recite the complete paradigm taught in this level:
تَقَاتَلَ يَتَقَاتَلُ تَقَاتُلًا فَهُوَ مُتَقَاتِلٌ الأَمْرُ مِنْهُ تَقَاتَلْ وَالنَّهْيُ عَنْهُ لَا تَقَاتَلْ
It contains the active past and Mudhaari', Masdar, Ism Fa'il, imperative, and prohibitive.

4. Understand the Paradigm by Slots

مُتَقَاتِلٌIsm Fa'il
تَقَاتَلْImperative

This lesson does not add passive forms or an Ism Maf'ool to this paradigm.

5. Bab Mufaa'alah vs Bab Tafaa'ul

Both doors contain an Alif after the first root letter, but Bab Tafaa'ul adds one more feature at the beginning.

Key differenceExamplePattern
Inserted Alif onlyقَاتَلَفَاعَلَ
Prefixed تَـ + inserted Alifتَقَاتَلَتَفَاعَلَ

So the prefixed تَـ is the clearest extra marker of Bab Tafaa'ul.

6. Command and Prohibition

MeaningFormCategory
Fight one another!تَقَاتَلْImperative
Do not fight one another!لَا تَقَاتَلْProhibitive

Both forms retain the prefixed تَـ and the inserted Alif.

7. A Simple Map of the Level

Remember these points:
1. Bab Tafaa'ul uses the past pattern تَفَاعَلَ.
2. Example: تَقَاتَلَ, root ق، ت، ل.
3. Its two main signs are prefixed تَـ and an Alif after the first root letter.
4. Masdar: تَقَاتُلٌ = fighting or engaging one another.
5. مُتَقَاتِلٌ is the Ism Fa'il.
6. Command/prohibition: تَقَاتَلْ / لَا تَقَاتَلْ.
7. Compared with Bab Mufaa'alah, the added initial تَـ is the clearest difference.
8. Passive forms and Ism Maf'ool are not part of this lesson's paradigm.
