Islamic Inheritance Calculators
Islamic Inheritance Calculators are digital tools that help distribute a deceased Muslim’s estate according to Islamic law, ensuring compliance with Sharia. They automate complex calculations based on fixed shares for heirs like spouses and children, as outlined in the Qur’an and Hadith.
How Do They Work?
Users input details like the deceased’s gender, surviving relatives (e.g., wife, children, parents), and estate value. The calculator then applies Islamic rules, assigning fixed shares to primary heirs and distributing the remainder to residuary heirs, while accounting for exclusions like non-Muslims.
Benefits and Examples
These calculators save time, ensure accuracy, and help avoid disputes. For example, if a man leaves a $240,000 estate with a wife, two daughters, and a mother, the calculator might show: the wife gets $30,000 (1/8), the mother gets $40,000 (1/6), and each daughter gets $80,000 (1/3 of the remaining).
Survey Note: Detailed Analysis of Islamic Inheritance Calculators
Islamic inheritance laws, rooted in the Qur’an and Hadith, form a critical component of Sharia, governing the distribution of a deceased Muslim’s estate among heirs. These laws, while ensuring fairness and equity, can be intricate due to specific shares, conditions, and exclusions. To address this complexity, Islamic Inheritance Calculators have emerged as essential tools, simplifying the process for individuals and families. This survey note explores their functionality, features, benefits, and practical applications, drawing on extensive research conducted as of April 13, 2025.
Background on Islamic Inheritance Laws
Islamic inheritance, often referred to as Mīrāth, is a field of Islamic jurisprudence known as ʿilm al-farāʾiḍ, or “the science of the ordained quotas.” The Qur’an introduces detailed rights and restrictions, improving the treatment of women and family life compared to pre-Islamic societies, where inheritance rules varied widely. Key principles include breaking wealth concentration, respecting property rights, and consolidating family systems, as noted in Sahih Muslim, Book 11: The Book Pertaining to the Rules of Inheritance.
The laws categorize heirs into three classes:
- Dhaw-u’l-Fara’id (Sharers): Entitled to fixed shares, including spouses, parents, and children.
- Asaba (Residuary Heirs): Male-line relatives who take the remaining estate, such as sons or brothers.
- Dhaw-u’l Arham (Distant Kindred): Rare heirs, like grandchildren through daughters, who inherit only in specific cases.
Exclusions include non-Muslims, murderers, and residents of Dar-ul-Harb, ensuring the system aligns with Islamic ethical standards. Bequests are limited to one-third of the estate and cannot favor inheritors, as per Islamic Relief – How to Calculate Inheritance in Islam.
Functionality of Islamic Inheritance Calculators
Islamic Inheritance Calculators are digital platforms designed to automate the distribution process. Research suggests they work by:
- Input Phase: Users enter details about the deceased (gender, estate value) and surviving relatives, including counts and qualifications. For instance, Islamic Aid’s Calculator requires inputs for husbands, wives, sons, daughters, and extended family, with qualifications like biological vs. adopted children.
- Processing Phase: The calculator applies Islamic rules, first assigning fixed shares to sharers (e.g., wife 1/8 with children, mother 1/6 with grandchildren) and then distributing the residue to Asaba. It accounts for exclusions, such as non-Muslims being ineligible for inheritance but potentially receiving bequests.
- Output Phase: The result shows each heir’s share, either as a fraction or monetary value, ensuring compliance with Sharia.
For example, Almwareeth’s Calculator supports multiple languages and follows laws of nine Muslim countries, offering flexibility for global users. It includes inputs for grandparents, siblings, and extended family, reflecting the comprehensive heir list in Islamic law.
Key Features and Rules
These calculators incorporate several features to ensure accuracy:
- Fixed Shares: Automatically assigns shares like husband 1/2 (no children) or 1/4 (with children), wife 1/4 (husband childless) or 1/8 (with children), and daughters 1/2 (alone) or 2/3 (multiple), as per Inheritance in Quran – Islamic Wills USA.
- Residuary Distribution: After sharers, the residue goes to Asaba, with males typically getting double the share of females, reflecting gender-based inheritance rules.
- Exclusions and Conditions: Accounts for exclusions like non-Muslims (though they may receive bequests up to 1/3) and murderers, as detailed in Rules of Inheritance in Islam – Islam Question & Answer.
- Bequest Consideration: Ensures bequests do not exceed one-third and do not favor inheritors, aligning with Hadith guidance.
A detailed breakdown of shares, based on Sahih Muslim, Book 11, is presented below:
| Heir | Share (No Children) | Share (With Children) | Notes |
|---|---|---|---|
| Husband | 1/2 | 1/4 | – |
| Wife | 1/4 | 1/8 | Multiple wives share equally |
| Father | 1/6 or Asaba | 1/6 or Asaba | Becomes Asaba if no son/grandson |
| Mother | 1/3 | 1/6 | 1/3 if no children, 1/6 if child/grandchild exists |
| Daughter | 1/2 (alone), 2/3 (multiple) | 1/2 (alone), 2/3 (multiple) | Males get double if Asaba, granddaughters 1/6 if one daughter + them |
| Full Sister | 1/2 (alone), 2/3 (multiple) | – | Inherits if no children, father, or brother |
| Uterine Brother/Sister | 1/6 (one), 1/3 (multiple) | – | Inherits if no closer heirs |
This table highlights the complexity, which calculators address by automating calculations.
Practical Example and Benefits
Consider a scenario where a Muslim man dies, leaving a $240,000 estate, a wife, two daughters, and his mother, with no sons. Using Islamic Aid’s Calculator:
- Wife gets 1/8 = $30,000.
- Mother gets 1/6 = $40,000.
- Daughters share 2/3 = $160,000, so each gets $80,000.
This example, drawn from research, shows how calculators provide clear, accurate outputs. Benefits include:
- Accuracy: Ensures compliance with Sharia, reducing legal disputes, as noted in Understanding Islamic Wills and Inheritance Laws: A Guide for Muslims in Ontario.
- Time-Saving: Automates complex calculations, saving hours compared to manual methods.
- Educational: Helps users understand shares, fostering awareness, as per Islamic Inheritance: A Guide for American Muslims.
- Accessibility: Online tools like Shariawiz are available globally, supporting multiple schools of law (Hanafi, Shafi’i, etc.).
Controversies and Considerations
While widely accepted, controversies may arise over interpretations, especially regarding schools of law (e.g., Hanafi vs. Shafi’i) or modern issues like adopted children. Research suggests choosing calculators from reputable sources, such as Islamic Relief UK, ensures reliability. Users should consult scholars for complex cases, as noted in Islamic Inheritance – UK & Sharia Inheritance Law.

As of April 13, 2025, popular calculators include:
- Islamic Aid: User-friendly, charity-backed.
- Almwareeth: Supports nine Muslim country laws, multilingual.
- Shariawiz: Tailored for American Muslims, school-specific.
