Can I Leave More Than One-Third in My Islamic Will?

The short answer: the free part of your estate is one-third, it cannot normally go to someone who already inherits, and anything beyond one-third depends on your heirs agreeing after your death.

Where the one-third comes from

Sa'd ibn Abi Waqqas, seriously ill, asked the Prophet (peace be upon him) whether he could give away two-thirds of his wealth, then half, then a third. Only the third was allowed, and even that was called a lot — leaving children provided for is better than leaving them dependent on others.

A wasiyyah is paid out at a specific point in the order of settling an estate:

Order What is paid
1 Funeral and burial costs
2 Debts, including mahr and outstanding obligations
3 The wasiyyah, up to one-third of what is left
4 The remainder, divided by Faraid among the fixed heirs

So the one-third is a third of the net estate, not of the gross value.

The second limit: no bequest to an heir

The one-third is not a free top-up for a favourite child. A well-known hadith narrated by Ibn Abbas has the Prophet saying that Allah has given every right-holder their right, "so there is no will for any inheritor." Classical Sunni law therefore treats a bequest to someone who already inherits as something the executors do not carry out unless the other heirs consent.

That means your one-third is for people the Faraid shares leave out, such as:

Where the madhabs differ

The headline rule is agreed. The detail is not.

Point Position
Heirs' consent to an over-size or heir-directed bequest Hanafi, and the dominant Shafi'i and Hanbali view, plus one Maliki view: valid but conditional, and the consent counts only after death
Alternative view Some Maliki, Shafi'i and Hanbali scholars: such a bequest is void even with agreement, unless the heirs simply gift the money afterwards
Partial consent If some agree and others refuse, it is paid only from the consenting heirs' portions
When ownership passes to the legatee Hanafi and Shafi'i: at death. Maliki and Hanbali: on acceptance

Islamic Will Pro lets you pick one of five settings — Hanafi, Maliki, Shafi'i, Hanbali or Generic — and applies that school's shares.

Worked example

Net estate of 300,000 after funeral costs and debts. The will leaves the full one-third to a mosque building fund. The heirs are a wife, two sons and a daughter.

Recipient Basis Amount
Mosque fund wasiyyah, 1/3 of 300,000 100,000
Wife 1/8 of the remaining 200,000 25,000
Son residue 175,000 in 2:2:1 70,000
Son residue 70,000
Daughter residue 35,000

Had the will left half the estate to a nephew, and the heirs did not agree, he would receive one-third — 100,000 — and the other 200,000 would go back into the Faraid pot.

What UK and US law actually allows

Neither system forces a fixed family split on you, so a Faraid-based will is normally given effect. Two limits are worth knowing.

England and Wales. Under section 1 of the Inheritance (Provision for Family and Dependants) Act 1975, a spouse or civil partner, a former spouse who has not remarried, a cohabitant of two years, a child, a person treated as a child of the family, or anyone the deceased was maintaining can ask the court for reasonable financial provision. A Faraid will is not void, but a widow or daughter left a small share may have a claim. The will must also be signed and witnessed properly.

United States. Most states give a surviving spouse an elective share, commonly one-third to one-half of the estate, and it overrides a contrary will. In community property states the spouse already owns half the marital property. Since a Quranic widow's share can be as low as one-eighth, a US Islamic will usually needs the spouse's position dealt with deliberately — often by a waiver, or by directing the one-third to her where that is permissible.

Frequently asked questions

Can I leave more than one-third of my estate in my wasiyyah?

Not as of right. The classical limit is one-third of the net estate after funeral costs and debts. More than that depends on the remaining heirs agreeing to it.

Can I leave extra to one of my children?

A child who inherits is a Quranic heir, so a bequest to them is not carried out unless the other heirs consent. Most jurists count that consent only once you have died.

Does the one-third have to be given to charity?

No. It can go to anyone who is not already an heir: a non-Muslim relative, a step-child, a grandchild whose parent is alive, a friend, a mosque or a charity.

Will a UK or US court enforce my one-third?

Usually yes, since both systems let you give your estate away by will. But a dependant can claim in England and Wales, and a spouse in most US states can elect a statutory share.
