Islamic Law of Inheritance Calculator

A Professional Tool for Accurate Sharia-Compliant Estate Distribution (Fara’id)

Total Shares Distributed

240,000.00

Formula Explanation: The calculation is based on the fixed shares (‘Fard’) prescribed in the Quran. The wife receives 1/8th when children are present, and both father and mother receive 1/6th each. The remaining estate is distributed to the children (‘Asaba’), with a son receiving double the share of a daughter. This tool provides an estimate based on these principles.

What is an Islamic Law of Inheritance Calculator?

An islamic law of inheritance calculator is a specialized digital tool designed to compute the distribution of a deceased Muslim’s estate according to the complex and divine rules of Fara’id (Islamic inheritance jurisprudence). This system, outlined in the Holy Quran and the Sunnah of Prophet Muhammad (PBUH), ensures a just and equitable division of assets among eligible heirs. Anyone tasked with executing a will or distributing an estate for a Muslim individual should use an islamic law of inheritance calculator to prevent errors and ensure compliance with Sharia law. Common misconceptions are that a will can override these rules entirely (it is limited to 1/3 for non-heirs) or that the distribution is arbitrary; in reality, it is a meticulously defined system.

The Formula and Mathematical Explanation Behind the Islamic Law of Inheritance Calculator

The core of the islamic law of inheritance calculator lies in a two-part system: fixed shares (Ashab al-Furud) and residuaries (Asaba). First, specific heirs are given prescribed fractional shares of the total estate. After these shares are distributed, the remaining portion of the estate is given to the residuary heirs. Our islamic law of inheritance calculator automates this process.

The calculation steps are as follows:

1. Determine Net Estate: The total estate value is calculated after settling all debts, funeral expenses, and bequests (Wasiyyah), which cannot exceed one-third of the estate.
2. Allocate Prescribed Shares: Fixed shares are given to primary heirs. For example, a wife receives 1/8 if the deceased had children, and parents each receive 1/6.
3. Distribute the Residue: The remaining estate goes to the ‘Asaba’. Children are the most common residuaries. When sons and daughters inherit together, they share the residue in a 2:1 ratio (a son’s share is double a daughter’s).

Variable	Meaning	Unit	Typical Range
E	Total Net Estate	Currency	Positive Value
S	Number of Sons	Integer	0+
D	Number of Daughters	Integer	0+
Fshare	Fractional Share of an Heir	Fraction (e.g., 1/8)	1/8, 1/6, 1/4, 1/3, 1/2, 2/3

Variables used in the islamic law of inheritance calculator.

Practical Examples (Real-World Use Cases)

Example 1: Deceased Male with Wife, Children, and Parents

An individual passes away leaving a net estate of 480,000. He is survived by his wife, one son, two daughters, and both of his parents.

• Inputs for the islamic law of inheritance calculator:
  • Total Estate: 480,000
  • Heirs: 1 Wife, 1 Son, 2 Daughters, Father, Mother
• Calculation:
  • Wife’s Share (1/8): 60,000
  • Father’s Share (1/6): 80,000
  • Mother’s Share (1/6): 80,000
  • Remaining for Children: 480,000 – 60,000 – 80,000 – 80,000 = 260,000
  • Children’s Shares (1 son x 2 parts + 2 daughters x 1 part = 4 parts):
    • Son’s Share (2/4 of residue): 130,000
    • Each Daughter’s Share (1/4 of residue): 65,000

Example 2: Deceased Female with Husband and No Children

An individual passes away leaving a net estate of 300,000. She is survived by her husband and her father, but no children.

• Inputs for the islamic law of inheritance calculator:
  • Total Estate: 300,000
  • Heirs: Husband, Father
• Calculation:
  • Husband’s Share (1/2, as there are no children): 150,000
  • Father’s Share (Residue): 150,000

2. Select the Deceased’s Gender: Choose whether the deceased was male or female, as this affects the spouse’s share.
3. Specify the Heirs: Enter the number of wives, sons, and daughters, and use the checkboxes to indicate if the father and mother are surviving.
4. Review the Results: The islamic law of inheritance calculator will instantly display the breakdown. You will see the share for each heir category, a detailed table with amounts and fractions, and a dynamic chart visualizing the distribution.

Key Factors That Affect Islamic Law of Inheritance Calculator Results

• Debts and Funeral Expenses: These must be paid before any distribution. A large debt load significantly reduces the net estate available to heirs.
• Bequests (Wasiyyah): A person can will up to 1/3 of their property to non-heirs. This is deducted before the Fara’id calculation. Using a tool like our Islamic Will Template can clarify this.
• Number and Gender of Children: The presence of a son makes all children residuary heirs (‘Asaba’) and changes the distribution dynamics completely compared to a scenario with only daughters.
• Presence of Parents or Grandparents: Parents are primary heirs with fixed shares, which reduces the amount available for other relatives. Their presence can impact the results of the islamic law of inheritance calculator significantly.
• Presence of a Spouse: A surviving husband or wife is always entitled to a share, which is larger if the deceased had no children.
• The Principle of ‘Aul’ (Increase): In rare cases, the sum of the prescribed fractional shares can exceed 1. In this situation, all shares are proportionally reduced. This is a complex rule handled by an advanced islamic law of inheritance calculator.

Frequently Asked Questions (FAQ)

1. Why does a son inherit twice the share of a daughter?

This rule is based on Quran 4:11. Islamic jurisprudence explains this by noting the different financial responsibilities placed on men, who are obligated to provide for their families (wife, children, and sometimes other relatives), while a woman’s inheritance is hers alone with no such obligation. Her financial needs are met by her husband or father.

2. Can a non-Muslim inherit from a Muslim?

No, according to the majority of Islamic scholars, difference in religion is an impediment to inheritance. A non-Muslim cannot inherit from a Muslim relative under Fara’id rules, though they can be the recipient of a bequest (Wasiyyah) from the allowed one-third portion of the estate.

3. What about adopted or step-children?

Adopted children and step-children are not considered legal heirs under traditional Islamic law and do not have an automatic right to inheritance. However, they can be granted a gift during the person’s lifetime or be included in the one-third bequest (Wasiyyah).

4. What happens if an heir dies before the estate is distributed?

This is a complex scenario known as ‘Munaskhat’. The deceased heir’s share is calculated, and then that share itself is distributed among their own living heirs according to Islamic law. This requires a multi-generational calculation, a feature found in a very advanced islamic law of inheritance calculator.

5. Does this calculator cover all possible heirs?

This specific islamic law of inheritance calculator focuses on the most common primary heirs: spouse, children, and parents. Islamic inheritance law includes many other potential heirs like grandparents, siblings, uncles, and more, whose shares depend on the absence of closer relatives.

6. What is ‘Radd’ (Return)?

Radd is the opposite of ‘Aul’. It occurs if the sum of prescribed shares is less than 1 and there are no residuary heirs (‘Asaba’). In this case, the remaining portion of the estate is returned to the prescribed-share heirs proportionally, except for the spouse. Our Fiqh of Finance section explains this further.

7. Can I give all my wealth to one child?

No. You cannot disinherit a rightful heir or change the prescribed Quranic shares through a will. Any such declaration would be void under Sharia law. The islamic law of inheritance calculator shows the mandatory, non-negotiable shares.

8. How is Zakat related to inheritance?

Any unpaid Zakat is considered a debt and must be paid from the estate before distribution. You can use a Zakat Calculator to determine any outstanding amounts. The same applies to other religious obligations like unpaid Kaffarah.
