Trilateral Bare Regular - Bab 3: Sami'a Yasma'u Introduction

1. Bab 3: Sami'a Yasma'u

The third regular door is introduced through its past and Mudhaari' forms.

FormSlot
سَمِعَPast
يَسْمَعُMudhaari'

Its pattern is the reverse of the previous Bab at the middle root letter: past with Kasrah, Mudhaari' with Fathah.
The verbal nouns given here are السَّمْعُ and السَّمَاعُ, meaning hearing.

2. Three Regular Doors Compared

Now compare the three regular doors studied so far.

Bab 3Bab 2Bab 1
سَمِعَ يَسْمَعُضَرَبَ يَضْرِبُنَصَرَ يَنْصُرُ

The key is to recognize each Bab as a fixed past–Mudhaari' pair rather than as an isolated verb.

3. Opening of the Sarf-e-Sagheer

Read the opening sequence in two connected blocks.
1. Active: سَمِعَ يَسْمَعُ سَمْعًا فَهُوَ سَامِعٌ.
2. Passive: سُمِعَ يُسْمَعُ سَمْعًا فَهُوَ مَسْمُوْعٌ.
This opening already gives you past, Mudhaari', verbal noun, Ism Fa'il, passive past, passive Mudhaari', and Ism Maf'ool.

4. Active and Passive Side by Side

Compare the same grammatical slot in active and passive voice.

PassiveActiveSlot
سُمِعَسَمِعَPast
يُسْمَعُيَسْمَعُMudhaari'
مَسْمُوْعٌسَامِعٌParticiple

The root stays the same; the pattern tells you whether the form is active or passive.

5. Derived Nouns Keep Their Known Weights

Bab changes do not replace the basic derived-noun weights already learned.

FormWeightType
سَامِعٌفَاعِلٌIsm Fa'il
مَسْمُوْعٌمَفْعُوْلٌIsm Maf'ool

This is an important reading habit: recognize the Bab of the verb, then recognize derived nouns by their own established patterns.

6. Read the Opening Sequence by Function

A useful way to revise this level is to group forms by function.

FormsFunction
سَمِعَ / يَسْمَعُActive verbs
سُمِعَ / يُسْمَعُPassive verbs
سَامِعٌDoer noun
مَسْمُوْعٌAffected noun

This makes the Sarf-e-Sagheer easier to understand than memorizing one uninterrupted line.

7. A Simple Map of the Level

Remember these points:
1. Bab 3 is سَمِعَ يَسْمَعُ.
2. Its verbal nouns here are السَّمْعُ and السَّمَاعُ.
3. The opening Sarf-e-Sagheer contains active and passive verb blocks.
4. سَامِعٌ is Ism Fa'il and مَسْمُوْعٌ is Ism Maf'ool.
5. Derived nouns continue to follow their established weights.
