Islamic Inheritance Calculator
Islamic inheritance (ʿilm al-farāʾiḍ) distributes an estate according to fixed shares set in the Quran. Select which relatives survived the deceased and this calculator estimates each heir's share, applying the rules of fixed shares (furūḍ), residue (ʿaṣaba), proportional reduction (ʿawl) and return of surplus (radd).
How Islamic inheritance works
- The Quran assigns fixed shares (furūḍ) to certain heirs — such as a spouse, parents and daughters. These are distributed first.
- Whatever remains after the fixed shares is the residue (ʿaṣaba), taken by the nearest male-line relatives, often following the rule of a male receiving the share of two females.
- If the fixed shares add up to more than the whole estate, ʿawl is applied: every share is reduced proportionally.
- If there is a surplus and no residuary heir, radd returns it to the fixed-share heirs in proportion to their shares — the spouse is excluded from the return.
Frequently asked questions
- How is inheritance divided in Islam?
- Islam divides an estate using fixed shares set out in the Quran (furūḍ) for close relatives, with the remainder (ʿaṣaba) going to the nearest agnatic relatives. Rules such as ʿawl and radd adjust the shares when they over- or under-shoot the estate.
- Why does a son receive more than a daughter?
- In many cases a son receives twice the share of a daughter because, under Islamic law, men carry the financial responsibility of maintaining their wives, children and other dependants, while a woman's wealth is hers alone.
- Is this calculator a fatwa?
- No. It is an educational estimate based on the mainstream Sunni position and does not handle every rare case. For an authoritative, binding distribution, consult a qualified scholar.
