Built for students, teachers, and anyone making sense of an estate.
FairShare walks you through a short questionnaire that only asks what's relevant for your family. The result shows up as a tree, with the Quranic basis for each share one tap away.
Five schools of thought
Compare General, Hanafi, Maliki, Shafi'i, and Hanbali side by side. Where they differ, every ruling is shown with its reasoning.
Quranic foundation
Every share is linked to the verse that prescribes it. Surah An-Nisa 4:11, 4:12, and 4:176 are right there, so you can see the source for yourself.
Handles the edge cases
Fixed shares, residuary heirs, blocking (Hajb), Awl, Radd, and the well-known special cases like Umariatan, Musharakah, and Grandfather-with-siblings.
Bilingual English & Arabic
Full right-to-left layout for Arabic. Pick the language at first launch or switch any time in Settings.
Offline & private
Calculations run locally in your browser or on your device. No account, no analytics, no ads. The web app is an installable PWA that keeps working offline.
Export & save
Save calculations for later, export a clean PDF report, or share the family tree as an image. Useful for study circles or family discussions.
Surah An-Nisa
Every share, linked to its source.
When FairShare gives a daughter 1/2, a wife 1/4, or a mother 1/3, you can tap the heir to see the exact verse that governs the share. The reasoning isn't hidden inside the code. It's shown alongside every result.

An educational tool, not legal or religious advice.
FairShare illustrates how an estate would be distributed under the classical rules of Fara'id. Actual distributions depend on jurisdiction, debts, wasiyyah (bequests), and other factors outside the scope of this calculator. Before acting on any calculation, please consult a qualified mufti or Islamic scholar familiar with your family's specific circumstances, alongside a licensed attorney for the legal and tax aspects of estate settlement.
Frequently asked questions
What is Fara'id?
+
Fara'id is the classical Islamic law of inheritance, derived primarily from Surah An-Nisa in the Quran (verses 4:11, 4:12, and 4:176) and detailed in centuries of scholarly work. It assigns prescribed shares to specific heirs (spouses, parents, children, and siblings) and gives rules for distributing whatever remains.
How is inheritance distributed in Islam?
+
It works in tiers. Fixed-share heirs (ashab al-furud) receive their prescribed fractions first: 1/2, 1/4, 1/8, 2/3, 1/3, or 1/6. Then residuary heirs (asabah) take what's left. Three special rules then take over: Awl, Radd, and Hajb (blocking). They cover cases where shares exceed the estate, fall short, or where a closer heir prevents a more distant one from inheriting.
What's the difference between the four Sunni schools on inheritance?
+
The four Sunni schools (Hanafi, Maliki, Shafi'i, and Hanbali) agree on most rulings but diverge in specific edge cases. The Grandfather-with-siblings case, the Musharakah (shared) case, and certain residuary scenarios all have meaningful differences. FairShare's Compare Schools view shows you exactly where they differ for any given family scenario.
Does FairShare handle Shia (Ja'fari) inheritance rules?
+
No. FairShare currently covers the Sunni five-madhhab framework (General, Hanafi, Maliki, Shafi'i, Hanbali). Shia inheritance has substantially different rules and isn't supported in this version.
Can I use FairShare offline?
+
Yes. The web app is an installable PWA: once you've loaded it, the calculator works without a connection. The iOS app is offline by design. In both cases, the calculation engine runs entirely on your device.
Does FairShare collect any data?
+
No. FairShare collects, transmits, and stores no personal data. Saved calculations and your language and madhhab preferences live only in your browser (web) or on your device (iOS). You can read the full policy at /fairshare/privacy.
What is Awl? What is Radd?
+
Awl is the proportional reduction applied when fixed shares total more than 100% of the estate. Every heir's share shrinks proportionally so the total fits. Radd is the opposite. When fixed shares total less than 100% and there are no residuary heirs, the surplus is redistributed back among the eligible fixed-share heirs. FairShare detects and applies both automatically.
Is FairShare a substitute for a qualified scholar?
+
No. FairShare is an educational reference. For an actual estate distribution, please consult a qualified mufti or scholar familiar with your family's specific circumstances, alongside a licensed attorney for the legal and tax aspects in your jurisdiction.
How much does FairShare cost?
+
FairShare is free. There are no in-app purchases, no subscriptions, no ads.
What languages are supported?
