What Is an Islamic Inheritance Calculator?

An Islamic Inheritance Calculator is a digital tool that helps Muslims distribute a deceased person's estate according to the rules prescribed in the Quran and Sunnah. This process, known as Mirath (مِيرَاث) in Arabic, follows specific mathematical formulas that Allah has revealed in Surah An-Nisa.

Islamic inheritance law is one of the most detailed legal frameworks in the Quran. Unlike man-made laws that change over time, these divine instructions have remained unchanged for over 1,400 years. Our Islamic Inheritance Calculator implements these exact rules to ensure 100% Sharia compliance.

The primary verses governing Islamic inheritance are found in Surah An-Nisa (4:11-12) and Surah An-Nisa (4:176). These verses specify exact fractions for different categories of heirs, leaving no room for ambiguity or dispute.

How to Use This Islamic Inheritance Calculator

Using our Islamic Inheritance Calculator is simple and straightforward. Follow these 4 steps to calculate the proper distribution of any estate:

Step 1: Enter Deceased Information

Start by specifying the gender of the deceased person. This is crucial because it determines which relatives qualify as heirs. For example, only a female deceased can have a husband as an heir, while only a male deceased can have wives.

Step 2: Enter the Estate Value

Enter the net value of the estate after deducting funeral expenses, outstanding debts, and any valid bequests (wasiyyah). Remember that bequests cannot exceed one-third of the estate and cannot be given to legal heirs.

Step 3: Add Surviving Heirs

Add all surviving heirs using either Detailed Mode (with individual names) or Quick Mode (numbers only). Our Islamic Inheritance Calculator supports 16+ heir types including spouse, parents, children, grandchildren, grandparents, and siblings.

Step 4: View Results

The Islamic Inheritance Calculator will display each heir's share as both a fraction and exact amount. You can print, copy, download as PDF, or share the results.

Quranic Fixed Shares in Islamic Inheritance

The Quran prescribes six fixed shares (الفُرُوض المُقَدَّرَة) that form the foundation of Islamic inheritance law. Our Islamic Inheritance Calculator implements all of these shares accurately:

16 Heir Types Supported by Our Islamic Inheritance Calculator

Our Islamic Inheritance Calculator supports all heir types recognized in classical Islamic jurisprudence (fiqh). These include:

• Spouse: Husband (for female deceased) or Wife/Wives (for male deceased, up to 4)
• Parents: Father and Mother
• Children: Sons and Daughters (unlimited)
• Grandchildren: Son's Sons and Son's Daughters
• Grandparents: Paternal Grandfather and Grandmother(s)
• Full Siblings: Full Brothers and Full Sisters (same father and mother)
• Paternal Half-Siblings: Paternal Brothers and Sisters (same father only)
• Maternal Half-Siblings: Maternal Brothers and Sisters (same mother only)

Special Cases: 'Awl, Radd, and Umariyyatan

Our Islamic Inheritance Calculator automatically handles complex scenarios that arise in inheritance distribution:

'Awl (العَول) - Proportional Reduction

'Awl occurs when the total of all fixed shares exceeds 100% of the estate. In this case, all shares are proportionally reduced so that everyone receives their fair portion. This ruling was established during the Caliphate of Umar ibn al-Khattab (RA).

Radd (الرَّد) - Proportional Return

Radd occurs when the fixed shares don't exhaust the entire estate and there are no residuary heirs ('asaba). The remaining estate is returned proportionally to eligible heirs, typically excluding the spouse according to most schools of thought.

Umariyyatan (العُمَرِيَّتَان) - The Two Omari Cases

These are special cases involving the mother's share when the deceased leaves a spouse and father but no children. Instead of receiving 1/3 of the total estate, the mother receives 1/3 of the remainder after the spouse's share.
