The Complete Guide to Islamic Inheritance (Faraid)

What Faraid Actually Is

Faraid (from the Arabic root meaning "obligatory portions") is the Islamic system of fixed inheritance shares set out chiefly in the Qur'an, Surah An-Nisa 4:11, 4:12 and 4:176, and clarified by the Sunnah of the Prophet Muhammad (peace be upon him). Unlike a Western will, where you generally choose who gets what, faraid is largely non-negotiable: after debts and funeral costs are settled and any valid one-third bequest is carried out, the remaining estate is distributed among specific relatives in specific, pre-set fractions. You don't decide these proportions — Allah did, and the reasoning classical scholars give is that this protects every family member, including the ones a will-writer might otherwise be tempted to overlook, favour, or shortchange.

If you've already read our guide to writing an Islamic will (wasiyya), you'll recognise the outline: debts and funeral costs first, then up to one-third to non-heirs if you choose, then faraid for the rest. That guide focuses on the will document — the legal container. This guide opens up what's actually inside it: how the fixed shares are worked out, heir by heir, with real numbers.

The Order of Operations: What Happens Before Faraid

Before a single faraid share is calculated, four things happen to the estate in a strict order. Getting this sequence right matters more than most people realise, because it changes the size of the "pie" that faraid then divides.

1. Funeral and burial costs are paid from the estate first.
2. Debts owed by the deceased are settled next — to people, banks, or institutions.
3. A valid bequest (wasiyya) of up to one-third of what remains may then be carried out, if the deceased left one.
4. The remainder — what's left after all three steps — is the amount faraid actually divides among the heirs.

This is why two people with the same gross estate and the same surviving family can end up with very different faraid outcomes: one may have significant debts or a generous one-third bequest, shrinking the pool the heirs share, while the other's estate passes through almost untouched. Every worked example below assumes step 4 has already happened — in other words, the "estate" in each example is the net distributable amount, not the gross value of everything the person owned.

The Core Heirs and Their Qur'anic Shares

Islamic inheritance jurisprudence identifies a group of relatives who are described as never being fully excluded from inheritance when they survive the deceased — sometimes called the primary or always-inheriting heirs: husband, wife, son, daughter, father, and mother. Their base shares, before any adjustment for a mix of other surviving relatives, are as follows.

Spouse shares

• Husband: receives 1/2 of his wife's estate if she left no children (or son's children); 1/4 if she left children.
• Wife (or wives collectively): receives 1/4 of her husband's estate if he left no children; 1/8 if he left children. If a man had more than one wife, this fraction is divided equally among them.

Children's shares

• A single daughter, with no sons, inherits 1/2.
• Two or more daughters, with no sons, share 2/3 between them equally.
• Where both sons and daughters survive, they do not take fixed Qur'anic fractions — instead they inherit as residuaries, sharing whatever remains after fixed-share heirs are paid, on the principle that a son's share equals that of two daughters (Qur'an 4:11).

Parents' shares

• Each parent — mother and father — receives 1/6 of the estate if the deceased left children (or son's children).
• If the deceased left no children, the mother receives 1/3, unless the deceased also left two or more siblings, in which case her share reduces to 1/6 and the father (or, in his absence, other rules) absorbs the residue.
• The father otherwise takes the residue after the mother's fixed share, when he is a residuary heir in that scenario.

Beyond this core group sits a wider circle: grandchildren (who may step into a deceased parent's position in specific, debated circumstances), full and consanguine and uterine siblings, grandparents, and others — each with conditions on exactly when they inherit and how much. Because so much depends on precisely who is alive and who has passed away first, faraid is best understood as a rules engine applied fresh to each family, not a single table you memorise once.

How the Calculation Actually Works: Step by Step

Here is the practical method scholars and calculators use, boiled down to five steps:

1. List every surviving relative and identify which are primary (always-inheriting) heirs and which are secondary heirs who only inherit in the absence of certain others.
2. Assign each qualifying heir their Qur'anic fraction (1/2, 1/4, 1/8, 1/3, 1/6, 2/3, etc.) based on the rules above and the specific combination of survivors.
3. Find a common denominator for all the fractions involved, so they can be added together as whole numbers over that denominator.
4. Check whether the shares total exactly one whole estate. If they add up to more than one, apply awl (proportional reduction). If they add up to less than one and there's no residuary heir to absorb the rest, apply radd (proportional return) to the eligible heirs.
5. Give any true residuary heirs (typically sons alongside daughters, or in some cases the father or brothers) whatever remains after the fixed-share heirs have been paid.

The trickiest part for most learners isn't the fractions themselves — it's steps 4 and 5, because they only apply in certain combinations of survivors. That's exactly what the worked examples below are for.

Worked Example 1 — Wife, Son and Daughter

A man dies leaving a wife, one son and one daughter, with a net distributable estate of $120,000 after debts, funeral costs and any bequest.

• The wife takes 1/8 because there are children: 1/8 × $120,000 = $15,000.
• The remaining 7/8 ($105,000) is residue, shared by the son and daughter in a 2:1 ratio (son gets double the daughter's share).
• That means the residue is split into 3 equal parts: the son takes 2 parts, the daughter 1 part.

$15,000 + $70,000 + $35,000 = $120,000 — the full estate, with nothing left over. Note there are no parents in this example; if the deceased's mother and/or father had also survived, each would take a fixed 1/6 before the son and daughter divided the residue.

Worked Example 2 — Husband, Mother and Father (No Children)

A woman dies leaving a husband, her mother, and her father, with no children and no siblings. Net estate: $90,000.

• The husband takes 1/2 because there are no children: 1/2 × $90,000 = $45,000.
• The mother takes 1/3 because there are no children and no siblings to reduce her share: 1/3 × $90,000 = $30,000.
• The father, as residuary heir in this scenario, takes what's left: $90,000 − $45,000 − $30,000 = $15,000.

Compare this to a case with surviving siblings: had this woman also left two or more brothers or sisters, her mother's share would drop from 1/3 to 1/6, with the father (or the residue rules in that scenario) absorbing the difference — a well-known adjustment scholars trace to the wording of the Qur'anic verse itself.

Worked Example 3 — When Shares Exceed the Whole Estate (Awl)

This is the case that surprises most beginners. A woman dies leaving a husband, two sisters, and her mother (a simplified illustrative case). Suppose the applicable fixed fractions in this scenario work out to husband 1/2, the two sisters together 2/3, and mother 1/6.

Using a common denominator of 6: husband = 3/6, sisters = 4/6, mother = 1/6. Added together: 3/6 + 4/6 + 1/6 = 8/6 — more than a whole estate, which is mathematically impossible to pay out as-is.

The classical solution, known as awl (increase), was applied by the companion and second caliph Umar ibn al-Khattab when faced with exactly this kind of case, and it was accepted by the four Sunni schools of law. Instead of removing an heir or arbitrarily cutting one person's share, every heir's share is proportionally scaled down by turning the total (8) into the new denominator:

Now the shares add up to exactly 8/8 — one whole estate. Everyone still inherits, and everyone's proportion relative to each other stays the same; only the absolute size of each share shrinks to make the total fit. This is a mainstream, long-accepted mechanism across Sunni jurisprudence, not a fringe workaround.

When Shares Fall Short: Radd (Return)

The mirror-image problem also exists. If the fixed-share heirs who survive don't have a residuary heir to soak up the leftover — for example, a lone mother and a lone daughter, with no father, no sons, and no other residuary relative — the Qur'anic fractions may add up to less than the whole estate. Something has to happen to the remainder.

The mainstream solution here is radd (return): the leftover is distributed back proportionally among the fixed-share heirs, in proportion to their original shares — with most schools of thought excluding a surviving spouse from participating in the radd, since a husband or wife is related by marriage rather than blood, while blood relatives absorb the remainder. Different schools and scholars hold nuanced positions on exactly which heirs qualify for radd and in what order, so a case that appears to need radd is precisely the kind of situation worth checking with a scholar or a properly built calculator rather than estimating by hand.

Country-by-Country: Where Faraid Carries Legal Weight

This is often the most confusing part for a new Muslim, especially one living outside a Muslim-majority country: faraid is a religious obligation everywhere, but it is not automatically enforced by courts everywhere. Broadly, countries fall into a few patterns.

Muslim-majority countries with codified Islamic family law

Many Muslim-majority states apply Islamic inheritance rules as binding law for their Muslim citizens through codified family or "personal status" codes — countries commonly cited in this category include Saudi Arabia, Egypt, Jordan, Pakistan, and the UAE, among others, each with its own local codification, court structure, and sometimes country-specific modifications or exceptions. A smaller number of Muslim-majority countries — Turkey and Tunisia are frequently cited examples — instead apply secular civil inheritance codes rather than classical faraid as state law. Because these frameworks are periodically reformed, always confirm the current position with a local lawyer rather than relying on a general guide for a specific estate.

The United States

US probate law does not apply faraid automatically. Each state runs its own intestacy statute, and — critically — American law generally grants near-total testamentary freedom: you can leave your estate to almost anyone, in almost any proportion, and courts will enforce a validly executed will as written. This cuts both ways for Muslims: it means nothing stops you from directing your will to follow faraid, but it also means nothing happens automatically if you don't. Without a valid, properly executed will, state intestacy law — not faraid — decides who inherits, and that outcome will often look very different from the Qur'anic shares. This is exactly the gap our Islamic will guide is built to close.

The United Kingdom

Sharia has no independent legal authority in the UK; England, Wales, Scotland and Northern Ireland each apply a single national legal system to everyone regardless of religion. As in the US, if you die intestate (without a will), statutory intestacy rules apply — not faraid — and the outcome frequently diverges from Islamic shares, particularly regarding unmarried partners or the treatment of children and parents. A will can voluntarily direct a faraid-compliant distribution and UK courts will generally uphold a validly executed will as written. One important nuance: the Inheritance (Provision for Family and Dependants) Act 1975 allows a spouse, former spouse, child, or person who was financially dependent on the deceased to apply to court if they feel a will (Islamic or otherwise) failed to make "reasonable financial provision" for them — a mechanism that exists independently of any religious content in the will and is worth discussing with a solicitor familiar with both frameworks.

Australia and Canada

Both operate on the same broad common-law principle as the US and UK: testamentary freedom, with courts recognising a validly executed will regardless of its religious content, alongside statutory "family provision" or dependant-relief laws (comparable in spirit to the UK's 1975 Act) that can let a spouse or child challenge a will they consider unfair. Without a will, provincial or state intestacy law applies rather than faraid. Ontario, Canada, at one point explored formal recognition of religious arbitration for family law matters including inheritance-related disputes, though the framework and its protections have shifted over time — another reminder to check current local law rather than older articles.

The universal practical takeaway

Regardless of which country you live in, the two-part lesson is the same: faraid is a religious obligation on you as a Muslim, but it usually needs a properly drafted, legally valid will to become the actual legal outcome. Get the local legal form right (witnessing, execution, state or country-specific requirements) and layer the faraid substance inside it — that combination is what protects your family both in the eyes of your faith and in a probate court.

Practical Assets That Complicate Faraid

Two modern wrinkles catch people out, and they're worth knowing about even though this guide can't resolve them for your specific estate.

Non-probate assets. Life insurance with a named beneficiary, a retirement account with a designated beneficiary, or a bank account held jointly with rights of survivorship can pass directly to that named person or co-owner under secular law — bypassing the probate estate, and therefore bypassing faraid entirely, unless you deliberately structure things otherwise. Many people are surprised to learn a large slice of their "estate" never technically reaches the faraid calculation at all.

Cross-border estates. If you hold property or accounts in more than one country, each country's law may claim jurisdiction over the assets located there, sometimes producing more than one applicable inheritance regime for a single person's estate. This is a genuinely specialist area — international estate planning for Muslims with assets abroad is one of the clearer cases where a single generic will is not enough, and professional advice earns its cost.
