A classically-recognized adjustment for when the Quranic fixed shares, added together, would claim more than the entire estate — all shares are proportionally reduced so they sum to exactly the whole estate, rather than exceeding it.

Does this work for Shafi'i, Maliki, or Shia Ja'fari inheritance rules?

No — this specifically implements Sunni Hanafi rules. The other schools differ on some details (for example, how a surviving grandfather interacts with siblings), which this tool doesn't model.

What heirs does this calculator actually support?

A surviving spouse (husband or wife), any number of sons and daughters, and whether the father and/or mother are also alive — always combined with at least one surviving child. It does not model siblings, grandparents, grandchildren, or more distant relatives.

Why do sons get twice the share of daughters?

This reflects the Quranic residue-splitting rule (Surah An-Nisa 4:11) applied when both sons and daughters survive alongside the deceased — a specific classical ruling, not an assumption made by this tool.

What happens if there are only daughters and no sons?

Daughters take a fixed share instead of splitting a residue: one daughter gets 1/2 of the estate, two or more daughters share 2/3 between them; any amount left over after other fixed shares goes to a surviving father, if there is one.

What if the estate value I enter includes debts or funeral costs?

This tool distributes the total value you enter; Islamic inheritance law requires funeral expenses, debts, and any bequests (up to 1/3 of the estate) to be settled first — enter the net estate value after those deductions for an accurate result.

Is this a legally binding distribution?

No — this is an educational estimate of Quranic share proportions for the specific, common heir combination it supports. Actual estate distribution should involve a qualified Islamic scholar and, where relevant, local inheritance law.

Why is this tool so narrowly scoped compared to a full Faraid calculator?

Because inheritance law involves classical exceptions (like the Umariyyatan ruling) and heir combinations (siblings, grandparents) where even authoritative sources gave genuinely conflicting figures during this project's own research — rather than risk an inaccurate figure in a domain with real religious and legal consequences, only the well-verified core case is computed.

About the Islamic Inheritance Calculator

Computes Islamic (Faraid) inheritance shares under Sunni Hanafi rules, for the core case of a deceased person with at least one surviving child.

How to use it

Enter the total estate value.
Select the surviving spouse, if any.
Enter the number of surviving sons and daughters.
Check whether the father and/or mother are surviving.
Read each heir's share.

Formula

Quranic fixed shares (spouse 1/4 or 1/8, parents 1/6 each) are allocated first, then sons and daughters split the remaining residue in a 2:1 ratio — unless there are daughters with no sons, in which case daughters take a fixed share (1/2 for one, 2/3 for two or more) instead, with any leftover going to a surviving father.

Worked example

A $100,000 estate with a husband, father, mother, and one daughter surviving triggers 'awl (the fixed shares alone would exceed the estate): after proportional reduction, husband gets ~23.1%, mother ~15.4%, father ~15.4%, and the daughter ~46.2% — verified against the classical 'awl calculation method.

Quranic Fixed Shares Used by This Calculator (Sunni Hanafi, deceased has ≥1 surviving child)

Quranic Fixed Shares Used by This Calculator (Sunni Hanafi, deceased has ≥1 surviving child)
Heir	Share	Condition
Husband	1/4	Alongside surviving children (this tool only computes cases with at least one child)
Wife	1/8	Alongside surviving children
Mother	1/6	Alongside surviving children
Father	1/6, plus any leftover residue if there are daughters only (no sons)	Alongside surviving children
One daughter, no sons	1/2	Fixed share when there are no sons
Two or more daughters, no sons	2/3 (shared equally among them)	Fixed share when there are no sons
Sons and daughters together	Residue split 2:1 (each son gets twice each daughter's share)	After fixed shares (spouse/parents) are allocated

Interpreting your result

Deliberately does not compute cases with NO surviving children — real research found a specific named classical exception (the "Umariyyatan" ruling) for certain spouse-and-parent combinations with genuinely conflicting figures even across authoritative sources, and siblings, grandparents, and more distant relatives aren't modeled at all. 'Awl (proportional reduction when fixed shares would exceed the whole estate) IS handled and was verified against a real classical textbook example (husband + father + mother + one daughter) before shipping.

Recommendations

• This is a starting point for understanding the Quranic share system, not a final legal distribution — always have a qualified scholar review the actual case, especially if siblings, grandparents, or other relatives are involved.

Frequently asked questions

Because a specific classical exception (the Umariyyatan ruling) applies to certain spouse-and-parent combinations in that situation, and different sources gave genuinely conflicting numeric answers even after this project's own research — rather than risk a wrong figure in a domain with real religious/legal weight, this case is left to a qualified scholar.
