What Is a Wasiyyah and How Do I Include One?

The wasiyyah is one of the most misunderstood elements of Islamic estate planning — and one of the most powerful tools available to Muslim families. Many families know the word but are unsure how it works legally in California, how much they can direct, or whether it can actually be enforced. This article answers all of that plainly.

What Is a Wasiyyah?

A wasiyyah is a voluntary testamentary bequest — a direction in your will or trust specifying that a portion of your estate, up to one-third, goes to a recipient who is not already an heir under fara'id. Its Qur'anic basis is found in Surah Al-Baqarah (2:180): "It is prescribed, when death approaches any of you, if he leaves any wealth, that he makes a bequest to parents and next of kin, according to reasonable usage."

The two-thirds remainder of your estate — after the wasiyyah — is distributed to your legal heirs per fara'id, the fixed Qur'anic inheritance shares. The wasiyyah and the fara'id shares operate in sequence: the bequest comes first, and heirs divide what remains.

Who Can Receive a Wasiyyah?

Under the Hanafi school — the default NASIB uses — a wasiyyah may be given to anyone who is not already a fara'id heir. Common recipients include:

• A masjid or Islamic center
• An Islamic school or educational endowment
• A charity such as Islamic Relief, Zakat Foundation, or a local community fund
• A non-Muslim family member who would not receive a fara'id share
• A stepchild or adopted child not covered under fara'id
• A cause, scholarship, or waqf (endowment) of your choosing

The restriction on giving a wasiyyah to an existing fara'id heir protects the inheritance rights of those heirs — it prevents a parent from effectively redirecting a child's share. This rule can be waived if all heirs consent after the death, but NASIB documents are drafted to reflect the default rule.

The One-Third Rule

The maximum permissible wasiyyah is one-third of the net estate — assets remaining after debts, funeral expenses, and other obligations are paid. The Prophet Muhammad ﷺ said: "One-third is much. It is better to leave your heirs well-off than to leave them poor and dependent on others." (Sahih al-Bukhari, Sahih Muslim.)

If a wasiyyah exceeds one-third and heirs do not consent, the excess may be challenged. Best practice: keep the wasiyyah at or clearly below one-third of your net estate to avoid ambiguity and protect the bequest's enforceability.

How It Works in a California Trust

In a California revocable living trust, the wasiyyah is specified as a separate bequest clause that appears before the residuary distribution to fara'id heirs. A simple example:

"I direct that ten percent (10%) of my net estate be distributed to Islamic Relief USA, a California-recognized nonprofit organization, as my wasiyyah. The remaining ninety percent (90%) shall be distributed to my heirs per Islamic inheritance principles as described in Article IV of this Trust."

This structure is legally binding on your trustee and fully enforceable under California law. Your heirs cannot override it simply by disagreeing — it is part of a valid, executed trust document. For a deeper look at how fara'id provisions work inside a trust, see our article on whether a revocable trust can follow Islamic inheritance rules.

Common Uses

• Masjid donation — the most common wasiyyah; a percentage directed to your local mosque or an Islamic center
• Islamic school endowment — supporting a school or scholarship fund
• Zakat-eligible charity — Islamic Relief, Zakat Foundation, local community organizations
• Non-Muslim family member — a parent, sibling, or child who would not otherwise receive a share
• Waqf contribution — a permanent endowment for ongoing charitable benefit

What Happens Without a Wasiyyah

If you die without specifying a wasiyyah, your entire estate passes to your fara'id heirs. Any wish to support your masjid, fund an Islamic school, or provide for a non-heir family member disappears with you unless it is documented. The intention alone has no legal force. In the FAQ section on wasiyyah, we address common questions about changing your wasiyyah and what happens when heirs disagree.

How NASIB Includes Your Wasiyyah

During the intake process, you specify your wasiyyah recipient and the percentage or dollar amount you wish to direct — up to one-third of your net estate. NASIB drafts the bequest clause into your trust or will, confirming the recipient name, the amount, and the order of distribution relative to your fara'id heirs.

The result is a single, legally executed document that fulfills both your Islamic obligations and California's requirements for a valid testamentary instrument. Simple, documented, and enforceable.
