Input the gross estate value, total debts, and any Wasiyyah amount. Net distributable estate is calculated automatically (Wasiyyah capped at 1/3).
Select whether the deceased is male or female — this determines whether a husband or wife is the surviving spouse.
Add spouse, number of sons and daughters, whether parents are alive, and any brothers or sisters. Each input updates results instantly.
Each heir shows their Quranic fraction, percentage, and dollar amount — with the specific verse or hadith basis listed clearly.
"Allah instructs you concerning your children: for the male, what is equal to the share of two females. But if there are [only] daughters, two or more, for them is two-thirds of one's estate. And if there is only one, for her is half. And for one's parents, to each one of them is a sixth of his estate if he left children. But if he had no children and the parents [alone] inherit from him, then for his mother is one-third. And if he had brothers or sisters, for his mother is a sixth... [This is] an obligation [imposed] by Allah. Indeed, Allah is ever Knowing and Wise."
"And for you is half of what your wives leave if they have no child. But if they have a child, for you is one fourth of what they leave... And for the wives is one fourth if you leave no child. But if you leave a child, then for them is an eighth of what you leave..."
"They request from you a ruling. Say, Allah gives you a ruling concerning one having neither descendants nor ascendants [as heirs]. If a man dies, leaving no child but [only] a sister, she will have half of what he left. And he inherits from her if she has no child. But if there are two sisters [or more], they will have two-thirds of what he left. If there are both brothers and sisters, the male will have the share of two females."

In some family compositions, the fixed Quranic shares add up to more than the total estate. For example: husband (1/2) + two daughters (2/3) = 7/6, which is greater than 1. ʿAwl resolves this by reducing all shares proportionally, so the estate is fully distributed fairly among all heirs.
Historical note: ʿAwl was a real controversy among the Companions. Caliph Umar ibn al-Khattab (RA) consulted with senior Companions and established the proportional reduction principle, which has been accepted by scholarly consensus (Ijma') ever since.
When only fixed-share heirs survive and there is no residuary heir (Asabah), the fixed shares may sum to less than 100% — leaving a surplus. Radd returns this surplus to the fixed-share heirs in proportion to their original shares, so no part of the estate remains undistributed.
Note: There is scholarly disagreement about whether the spouse participates in Radd. Most Hanafi scholars exclude the spouse; some other schools include them. This calculator applies the majority Hanafi position.
US courts do not automatically apply Islamic inheritance law. If a Muslim dies without a valid will in the United States, the estate is distributed according to the state's intestacy laws — which typically give the spouse most or all of the estate and may give parents nothing, contrary to Faraid.
To make a Faraid-compliant distribution legally binding, you need an Islamic will (wasiyyah) that is also valid under your state's laws. This typically requires the will to be written, signed in the presence of witnesses, and notarized per state requirements. The will explicitly names each heir and their Faraid share, and an executor who understands Islamic law is appointed to distribute accordingly.
Work with an attorney experienced in both Islamic law and US estate planning to create a will that is legally enforceable and Faraid-compliant.
A living trust can help avoid probate, maintain privacy, and ensure Faraid distribution happens promptly after death without court proceedings.
For complex family situations — predeceased children, multiple marriages, grandchildren, or non-Muslim heirs — always consult a qualified Islamic scholar alongside your attorney.
The obligatory shares of inheritance prescribed in the Quran. From 'fard' meaning obligatory duty. The six possible fractions are: 1/2, 1/4, 1/8, 2/3, 1/3, and 1/6.
Residuary heirs — those who inherit what remains after fixed shares are distributed. Sons are the primary Asabah. The father, brothers, and other male relatives are Asabah in the absence of closer heirs.
Proportional reduction — applied when fixed shares sum to more than 100%. Each heir's share is reduced proportionally so the estate is fully distributed fairly.
Return of surplus — applied when fixed shares sum to less than 100% and there is no Asabah. The surplus is returned to fixed-share heirs proportionally.
Blocking — when a closer heir excludes a more distant heir. Siblings are blocked by children or a surviving father. Mother's share is reduced from 1/3 to 1/6 by children or 2+ siblings.
An Islamic will or bequest — up to one-third of the net estate (after debts) may be distributed by will. Cannot be made in favor of an heir who already receives a Faraid share.
The net estate for Faraid distribution is what remains after: (1) funeral expenses, (2) all debts, and (3) any valid Wasiyyah. Only this net amount is divided among heirs.
A person who dies leaving neither children (descendants) nor parents (ascendants). Quran 4:176 specifically addresses the inheritance of a Kalalah, where siblings become primary heirs.
Faraid (فرائض) is the Islamic law of inheritance derived directly from the Quran — primarily Surah An-Nisa verses 4:11–12 and 4:176, supplemented by the Sunnah. Allah prescribes exact fractional shares for specific heirs and ends the verses with 'These are the limits [set by] Allah' (4:13), making compliance a religious obligation. The Prophet Muhammad (ﷺ) said: 'Learn the Faraid and teach it to the people, for it is half of knowledge' (Ibn Majah). Distributing an estate contrary to Faraid — for example, leaving everything to one child — violates the rights of other lawful heirs.
The Quran specifies exactly six possible shares: one-half (1/2), one-quarter (1/4), one-eighth (1/8), two-thirds (2/3), one-third (1/3), and one-sixth (1/6). Every fixed-share heir (ashabul-furud) receives one of these fractions depending on who else survives. For example, a wife receives 1/4 when the deceased has no children, and 1/8 when there are children. A sole daughter receives 1/2; two or more daughters share 2/3.
ʿAwl (عول) literally means 'increase' — it applies when the sum of all fixed shares exceeds the total estate (i.e. adds up to more than 100%). Rather than leaving some heirs unpaid, all fixed shares are reduced proportionally so that each heir receives a smaller but equitable fraction. ʿAwl was established by scholarly consensus (ijma') after the Companions of the Prophet (ﷺ) encountered this situation and Caliph Umar ibn al-Khattab (RA) endorsed the proportional reduction approach.
Radd (رد) literally means 'return' — it applies when the fixed shares of all heirs add up to less than 100% and there is no residuary heir (Asabah) to absorb the remainder. Rather than leaving the surplus undistributed, it is returned to the fixed-share heirs proportionally according to their original shares. There is scholarly difference of opinion about whether Radd applies to the spouse — most Hanafi scholars exclude the spouse from Radd, while some other schools include them.
Hajb (حجب) means 'screen' or 'block' — certain heirs who would otherwise inherit are excluded when closer relatives are present. There are two types: Hajb Hirman (total exclusion) and Hajb Nuqsan (reduction in share). A key example: siblings are totally excluded (Hajb Hirman) when the deceased leaves children or a surviving father. Similarly, the mother's share is reduced from 1/3 to 1/6 (Hajb Nuqsan) when the deceased has children or two or more siblings.
The Asabah are heirs who do not receive a fixed fraction but instead inherit whatever remains after all fixed shares are distributed. The primary Asabah are sons — and daughters inherit as Asabah alongside their brothers (receiving half a son's share, per Quran 4:11). Other Asabah include the father (when there are no children), full brothers, paternal half-brothers, and other male relatives along the agnatic line. If there are no Asabah and surplus remains, Radd returns it to fixed-share heirs.
Before any heir receives their Faraid share, three obligations must be settled in order: (1) Funeral expenses — the cost of washing, shrouding, and burial. (2) All debts — every financial obligation of the deceased, including to individuals and institutions. (3) Wasiyyah (will) — up to one-third of the remaining estate may be distributed according to a valid Islamic will, but only to non-heirs (a wasiyyah cannot supplement the Faraid share of an existing heir). Only what remains after all three are settled is distributed by Faraid.
No. US courts apply state intestacy laws, which distribute estates very differently from Faraid. Without a valid will, your estate will be distributed according to your state's default rules, which may give your spouse everything, ignore parents entirely, or otherwise diverge sharply from Islamic inheritance principles. To make a Faraid-compliant distribution legally enforceable, you need a state-valid Islamic will (wasiyyah) drafted with the assistance of an attorney familiar with both Islamic law and US estate planning. This calculator shows the correct Faraid distribution — implementing it legally requires a properly executed will.
