1. **Qur’an Source:**
Surah An-Nisā’, Surah 4, Ayah 12
وَلَكُمْ نِصْفُ مَا تَرَكَ أَزْوَاجُكُمْ إِن لَّمْ يَكُن لَّهُنَّ وَلَدٌ ۚ فَإِن كَانَ لَهُنَّ وَلَدٌ فَلَكُمُ ٱلرُّبُعُ مِمَّا تَرَكْنَ
Translation: If your wives have children, then you get one-fourth of what they leave.
Simple Meaning: The wife gets a fixed share first. Then the rest goes to the children by Allah’s rules.
2. **Hadith Source:**
Sahih al-Bukhari, Hadith 6732, Sahih
أَلْحِقُوا الفَرَائِضَ بِأَهْلِهَا، فَمَا بَقِيَ فَلِأَوْلَى رَجُلٍ ذَكَرٍ.
Meaning: Give the fixed shares to the people who are entitled to them. Then whatever is left goes to the nearest male relative.
Simple Explanation: First we give the wife her set share. Then we divide the rest between the children.
3. **How this is divided:**
- Wife gets $1/8$ because there are children.
- The rest is for the children.
- A son gets the share of $2$ daughters.
4. **Your example:**
If the total is $100$.
- Wife gets $100 \times 1/8 = 12.5$
- Left is $100 - 12.5 = 87.5$
5. **Split the children:**
- 1 son = $2$ shares
- 2 daughters = $1 + 1 = 2$ shares
- Total shares = $4$
So each share is $87.5 \div 4 = 21.875$
- Son gets $2$ shares = $43.75$
- Each daughter gets $1$ share = $21.875$
6. **Final division of $100$:**
- Wife: $12.5$
- Son: $43.75$
- Daughter 1: $21.875$
- Daughter 2: $21.875$
7. **Easy picture:**
Think of $100$ candies.
First give the wife $12.5$ candies.
Then give the rest to the children in parts.
The son gets twice as much as each daughter.
8. **Important note:**
If there are debts, funeral costs, or a will, those are handled before the division.
For exact family cases, ask a qualified scholar.
**Takeaway:**
The wife takes her fixed share first, then the children split the rest with the son getting twice each daughter’s share.
Allah knows best.
