Lesson

1. Bab Istif'aal

Bab Istif'aal is the second derived triliteral door in this section that begins with Hamzat-ul-Wasl.
Its basic pattern is اِسْتَفْعَلَ.
The visible prefix is اِسْتَـ — Hamzah, Seen, and Taa added before the original root letters.

2. Root Letters and Added Letters

In اِسْتَنْصَرَ, separate the root from the added prefix.

LettersType
ن، ص، رOriginal root letters
ا، س، تAdded letters

So the root remains ن-ص-ر, while اِسْتَـ creates the Istif'aal pattern.

3. Masdar and Meaning

The verbal noun is اِسْتِنْصَارٌ.
Its meaning in this lesson is to seek or request help.
So اِسْتَنْصَرَ means: he sought help.

4. Complete Sarf-e-Sagheer

Recite the complete Sarf-e-Sagheer together:
اِسْتَنْصَرَ يَسْتَنْصِرُ اِسْتِنْصَارًا فَهُوَ مُسْتَنْصِرٌ وَاُسْتُنْصِرَ يُسْتَنْصَرُ اِسْتِنْصَارًا فَهُوَ مُسْتَنْصَرٌ الأَمْرُ مِنْهُ اِسْتَنْصِرْ وَالنَّهْيُ عَنْهُ لَا تَسْتَنْصِرْ
This one line contains the active forms, passive forms, Ism Fa'il, Ism Maf'ool, imperative, and prohibitive.

5. Active and Passive Blocks

Now split the complete line into two main blocks.
1. Active: اِسْتَنْصَرَ يَسْتَنْصِرُ اِسْتِنْصَارًا فَهُوَ مُسْتَنْصِرٌ.
2. Passive: اُسْتُنْصِرَ يُسْتَنْصَرُ اِسْتِنْصَارًا فَهُوَ مُسْتَنْصَرٌ.
The two participles are close in shape, so read them carefully.

6. Ism Fa'il, Ism Maf'ool, Command and Prohibition
