Frequently asked questions

How is inheritance divided in Islam?
The estate is divided in two stages. First, the Quranic heirs with fixed shares (fara'id) — spouses, parents, and children — receive their prescribed fractions. The residue (asabah) then goes to the nearest male-line heirs, with sons receiving twice the share of daughters as the Quran specifies. The calculator works through these rules in the correct order, including cases where shares need proportional reduction.
What does a wife inherit?
The Islamic Inheritance Calculator (Faraid) is a free online tool that distributes an estate according to islamic inheritance (faraid) rules. enter the deceased's assets and the list of surviving heirs — spouse, children, parents, siblings, and grandparents — and the tool applies the fixed quranic shares, the 2:1 male-to-female. You enter a few values, and it returns an accurate result together with a step-by-step explanation, so it works as both a calculator and a quick reference for the underlying concept.
Why does a son receive twice a daughter’s share?
Yes — privacy is the core design principle here. The Islamic Inheritance Calculator (Faraid) runs entirely in your browser with client-side JavaScript, so the values you enter are never uploaded to any server, never stored, and never shared. Nothing is tracked, no account exists, and closing the page erases your inputs completely.
Can I leave a will on top of the fixed shares?
Yes, within limits: a valid Islamic will (wasiyyah) may dispose of up to one-third of the estate to non-heirs or charity, after debts and funeral expenses are settled. The Quranic heirs' fixed shares come from the remaining two-thirds and cannot be changed by the will. Leaving a bequest to an heir who already has a fixed share is restricted by most schools.
Is this calculator a fatwa?
The Islamic Inheritance Calculator (Faraid) is free, private, and accurate: it runs entirely in your browser (no uploads, no accounts), applies the standard calculation, and explains each step so you can verify the result. Distributes an estate according to Islamic inheritance (Faraid) rules. Enter the deceased's assets and the list of surviving heirs — spouse, children, parents, siblings, and grandparents — and the tool applies the fixed Quranic shares, the 2:1 male-to-female There is no limit on usage, and it works on any device.
Which heirs get fixed shares?
The spouse, parents, daughters, and several others — the Quran fixes their fractions explicitly. For example, a wife with children receives 1/8, a husband with children receives 1/4, and a mother with children receives 1/6; the calculator applies these before anything else.
What happens to whatever is left after the fixed shares?
It passes as residue (ta'seeb) to the nearest male-line relatives — the asabah. Sons then inherit at twice the share of daughters (2:1), which is the standard Sunni residue rule the calculator applies after the fixed shares are settled.
What if the fixed shares add up to more than 100%?
Through 'awl — proportional reduction. When fixed shares oversubscribe the estate (a classic case: husband 1/2 + two full sisters 2/3 = 7/6), every share is scaled down proportionally so the total fits exactly. The calculator handles this automatically.
Can the deceased leave extra to someone through a will?
Only within limits: a bequest (wasiyya) may cover up to one-third of the estate, and it cannot favor someone who already takes a fixed share unless the other heirs consent. The calculator distributes the faraid portion — any wasiyya is settled before that distribution begins.
