🔎 Frequently Asked Questions about the TRW Islamic Inheritance Calculator

Powered by TRW Law Firm – Bangladesh’s Leading Shariah-Compliant Legal Advisory

1. ✅ What is the purpose of the TRW Islamic Inheritance Calculator?

The TRW Islamic Inheritance Calculator is a free legal tool designed to help Muslims in Bangladesh and beyond calculate inheritance distribution in accordance with Islamic Shariah Law (Faraid). Developed by our Shariah-compliant legal team at TRW Law Firm, this calculator serves educational and practical purposes — assisting families, heirs, and legal representatives in understanding their Islamic inheritance rights with clarity and accuracy.

2. 🎯 Is the TRW Inheritance Calculator accurate?

Yes, we’ve taken meticulous steps to ensure the highest level of accuracy. The calculator has been tested against hundreds of verified Faraid test cases derived from classical Islamic jurisprudence (Fiqh al-Mirath). However, TRW Law Firm always advises that before executing any inheritance distribution, users verify results with a qualified Mufti or through our legal consultation services for binding legal application.

3. 📘 What types of Islamic inheritance test cases were used?

The tool has been validated using real-world scenarios and exam-style problems drawn from authoritative Islamic inheritance texts. These include issues such as:

• Sons, daughters, spouses, and parents as heirs

• Presence or absence of Asabah (residuaries)

• Shares of siblings, grandparents, etc.

• Complex ratios involving multiple heirs

Each case reflects accepted Hanafi, Shafi’i, and Maliki madhhab interpretations, ensuring broad usability across the Muslim world.

4. 📚 Which Islamic texts were used for validation?

We’ve referred to and cross-verified our inheritance logic using the following Shariah-compliant reference books:

• “Inheritance: Regulations and Exhortations” by Muhammad al-Jibaly (Al-Kitab & As-Sunnah Publications)

• “The Islamic Law of Succession” by Dr. A. Hussain (Darussalam Publications)

TRW Law Firm maintains an internal Shariah review panel to ensure that our tools align with Fiqh and Bangladesh’s legal environment.

5. 💻 How does the TRW tool compare with other Islamic inheritance calculators?

We believe that TRW Law Firm’s calculator is among the most accurate and professionally developed Islamic inheritance calculators online. Unlike many other tools, we:

• Apply verified cases from Islamic textbooks

• Avoid coding shortcuts or approximations

• Regularly audit results through legal and Islamic scholars

We continuously improve the system with user feedback and verified case expansion.

6. 🎓 Who developed this tool and do they have proper credentials?

While the calculator is inspired by contributions from Islamic students of knowledge and based on guidance from scholars such as Shaykh Waleed Basyouni, the tool itself is maintained and legally backed by TRW Law Firm, a trusted name in Islamic law in Bangladesh.

However, please note:
This calculator does not constitute a Fatwa or legally binding distribution order.
We recommend confirming distributions through our Shariah-compliant legal team or a certified Mufti.

7. 🚫 Are there any limitations to the TRW Inheritance Calculator?

Yes. For simplicity and broad accessibility, the calculator:

• Considers up to five generations of heirs

• Does not handle complex, rare cases (e.g., freed slaves, Radd, or Mawla issues)

• Uses the most widely accepted Fiqh opinion when there are minor differences among schools of thought

For nuanced and rare cases, TRW Law Firm offers custom Islamic inheritance legal opinions.

📜 Islamic Inheritance Rules (Faraid) Explained by TRW Law Firm

Comprehensive Guide to Prescribed Shares, Blocking Rules, and Ta’seeb Under Shariah Law in Bangladesh

At TRW Law Firm, we advise individuals and families on Islamic inheritance law (Faraid) in accordance with the Holy Qur’an and Shariah principles, harmonized with the legal framework of Bangladesh. Below is a detailed breakdown of prescribed inheritance shares, blocking rules, and special case scenarios, as interpreted from authoritative sources such as Surah An-Nisa and classical Islamic jurisprudence.

⚖️ Prescribed Shares (Al-Furud al-Muqaddarah)

These are the fixed shares ordained in the Qur’an that certain heirs receive before residual distribution (Ta’seeb):

👤 Husband [Surah An-Nisa 4:12]

• ½ Share: If the deceased leaves no offspring

• ¼ Share: If the deceased leaves offspring

👩 Wife (All wives share this collectively) [Surah An-Nisa 4:12]

• ¼ Share: If the deceased has no children

• ⅛ Share: If the deceased has children

👧 Daughter(s) [Surah An-Nisa 4:11]

• ½ Share: Only one daughter, no sons

• ⅔ Share: Two or more daughters, no sons

👧 Granddaughter(s) (Through son)

• ½ Share: One granddaughter, no son, daughter, or grandson

• ⅔ Share: Two or more granddaughters, no son, daughter, or grandson

• 1/6 Share: One daughter + one granddaughter, no son or grandson

👴 Father [Surah An-Nisa 4:11]

• 1/6 Share: If the deceased leaves children

👵 Mother [Surah An-Nisa 4:11]

• ⅓ Share: No children and no multiple siblings

• 1/6 Share: If children or multiple siblings are present

👴 Paternal Grandfather

• 1/6 Share: In the absence of father, and if there are children

👵 Grandmothers

• Paternal Grandmother

  • 1/6 Share: If no mother, father, or maternal grandmother

  • 1/12 Share: If maternal grandmother is present

• Maternal Grandmother

  • 1/6 Share: If no mother

  • 1/12 Share: If paternal grandmother is present

👩‍❤️‍👩 Full Sister [Surah An-Nisa 4:176]

• ½ Share: One full sister, no offspring, no brothers or male ancestors

• ⅔ Share: Two or more full sisters under same conditions

👩 Paternal Sister

• ½ or ⅔ Share: Subject to presence of other heirs

• 1/6 Share: If a full sister exists

🧬 Maternal Siblings [Surah An-Nisa 4:12]

• 1/6 Share: One maternal sibling

• ⅓ Share: Multiple maternal siblings
  (Applies when there are no male descendants or male ancestors)

⛔ Blocking (Hajib) Rules in Islamic Inheritance

Certain heirs are blocked from inheriting when closer heirs exist. This principle ensures inheritance is prioritized based on closeness in lineage.

Examples of Blocking:

• Son blocks: grandson, siblings, nephews, uncles, cousins

• Father blocks: grandfather, siblings, nephews, uncles

• Mother blocks: both paternal and maternal grandmothers

• Full Brother blocks: paternal siblings, nephews, cousins

• Full Sister can block only if there’s a female offspring

• Spouses cannot be blocked and do not block others

TRW Note: Accurate blocking requires expert legal and religious interpretation — consult our Islamic estate planning team for personalized advice.

📊 Ta’seeb (Residual Distribution)

After fixed shares are distributed, remaining estate goes to residuary heirs based on male lineage priority. Ta’seeb distribution follows a strict hierarchy:

Order of Residuary Heirs:

1. Sons & Daughters

2. Paternal Grandchildren

3. Father

4. Full Siblings

5. Paternal Siblings

6. Grandfather

7. Nephews & their descendants

8. Paternal uncles & their descendants

9. Emancipators (in absence of relatives)

📌 Key Islamic Inheritance Rules and Exceptions

🟢 2:1 Male-Female Rule [Surah An-Nisa 4:11, 4:176]

• Males of the same class receive double the share of females

• Not applicable to maternal siblings or prescribed shares

🟢 ‘Awal (Excess Total)

• If fixed shares exceed the total estate (i.e., more than 1), all shares are proportionally reduced

• Grandfather may override siblings in some cases

🟢 Radd (Share Shortfall)

• If the total is less than 1, the residual is redistributed among eligible heirs (excluding spouses)

🟢 Role Promotion (In absence of closer heirs)

• Grandfather acts as father

• Sister becomes daughter

• Granddaughter becomes daughter

• Paternal sister becomes daughter

🟢 Spouses

• Never block or be blocked

• Cannot receive an increased share in Radd

• Female Chain Continuity: Only the mother’s maternal line continues indefinitely

• Far Relatives Rule: If no standard heir remains, distant relatives may inherit
