How to Write an Islamic Will (Wasiyyah) Step by Step

Over half of Muslim adults in Western countries have no written will.

Without one, state or country intestacy laws determine who receives what. In most American states, the surviving spouse inherits the majority or all of the estate. Children may receive nothing until the spouse dies. Parents and siblings are excluded entirely. None of this aligns with faraid.

The Prophet, peace be upon him, said: "It is not permissible for any Muslim who has something to will to stay for two nights without having his will written and kept ready with him." (Sahih Bukhari 2738). This is a direct prophetic instruction with a specific timeframe.

The Two Functions of a Muslim's Will

A Muslim's will serves two distinct functions:

1. The wasiyyah: the discretionary bequest of up to one-third of the net estate to non-heirs or charitable causes.

2. The faraid distribution: directing the remaining estate to be distributed according to Islamic inheritance law.

A will that only addresses the wasiyyah and ignores faraid is incomplete. A will that only specifies faraid distribution without a wasiyyah wastes the discretionary one-third. The complete Islamic will addresses both.

Step 1: The Islamic Declaration

Every wasiyyah begins with the shahada and a declaration of faith. This establishes the document's religious foundation and signals to any court that the distribution follows religious conviction.

The declaration states that you are Muslim, believe in Allah and the Last Day, and direct your estate to be distributed according to Islamic law. It should reference the specific school of fiqh your family follows, as inheritance calculations differ slightly between the Hanafi, Maliki, Shafi'i, and Hanbali schools.

Step 2: List Debts and Obligations

Islamic inheritance applies to the net estate. Before any distribution, the estate settles four categories in this order:

1. Funeral and burial expenses (specify Islamic practice, simple burial)
2. Outstanding debts to creditors
3. Debts to Allah: unfulfilled zakat, unpaid kaffarah, hajj obligations
4. The wasiyyah bequest

Your will should explicitly list known debts and reference a debt inventory document you update regularly.

Step 3: The Wasiyyah Allocation

The wasiyyah permits up to one-third of the net estate after debts. Three rules:

• Cannot exceed one-third
• Cannot be directed to a Quranic heir unless all other heirs consent after your death
• Cannot be used to circumvent the faraid shares

What to use the wasiyyah for: non-heir dependents (adopted children, foster children, non-Muslim family members), a charitable endowment (waqf) for ongoing sadaqah jariyah, specific Islamic institutions or scholarship funds, particular family needs faraid doesn't cover.

Be specific. "One-third to charity" creates disputes. "10% to Masjid Al-Rahman building fund, 10% to Islamic scholarship fund at State University, 13.33% to adopted daughter Fatima bint Ahmad" is precise and enforceable.

Step 4: The Faraid Distribution Clause

This clause directs the remaining estate to be distributed according to Islamic inheritance law. Specify the school of fiqh, name a qualified Islamic scholar to calculate the shares, and reference the Quranic verses (4:11-12, 4:176) as the governing authority.

Do not attempt to specify exact fractions in the will itself. Heir composition changes over time. A will written when you have two children becomes inaccurate after a third is born. Direct that the distribution follow faraid as calculated at the time of death based on surviving heirs.

Step 5: Executor Appointment

The executor administers the estate. Choose someone who understands both Islamic inheritance and the legal system in your jurisdiction. You may need co-executors: one for Islamic compliance and one for legal administration.

Discuss the role with your chosen executor before naming them. Name an alternate in case the primary is unable to serve. Consider naming an Islamic organization that offers estate administration services as a backup.

Step 6: Guardianship for Minor Children

If you have minor children, name a guardian who will raise them according to Islamic values. Name an alternate. Specify your wishes regarding Islamic education, Quran memorization, and religious upbringing.

Document your reasoning. Courts evaluate the best interest of the child, and evidence that you thoughtfully selected a guardian based on the child's welfare strengthens the nomination.

Step 7: Asset Coordination

A will only governs assets that pass through probate. Assets with beneficiary designations, joint titles, or trust structures bypass the will entirely.

Review every asset. Probate assets include individually titled bank accounts, real estate in your name alone, personal property, and business interests. Non-probate assets include joint accounts, retirement accounts with named beneficiaries, life insurance policies, and payable-on-death accounts.

For faraid compliance, either restructure non-probate assets to flow through the will, or coordinate beneficiary designations to approximate the faraid distribution. The second approach requires recalculation whenever family composition changes.

Step 8: Legal Execution Requirements

A will must meet your jurisdiction's legal requirements to be enforceable. Most places require your signature, two witnesses who are not beneficiaries, and in some places, notarization.

Use witnesses who are not heirs under your will. Notarize regardless of whether your jurisdiction requires it. Store the original in a safe deposit box, your attorney's office, or a fireproof home safe. Give copies to your executor, your spouse, and your attorney.

Step 9: Letter of Instruction

Supplement your will with a letter of instruction. Not a legal document, but a practical guide for your executor and family. Include: location of important documents, digital account credentials (stored securely), and detailed funeral wishes (who should lead the janazah prayer, where you wish to be buried).

Update this letter annually. Unlike the will, no legal formalities are required to revise it.

Five Common Errors

Directing wasiyyah to a Quranic heir. Void unless all other heirs consent after death.

Exceeding the one-third wasiyyah limit. The excess is void.

Not naming a school of fiqh. Different schools calculate different shares in certain scenarios.

Failing to coordinate non-probate assets. Creates a situation where the will says faraid but the bulk of the estate bypasses the will entirely.

Not meeting legal execution requirements. A will that is Islamically perfect but legally deficient will be overridden by intestacy law.

When to Revise Your Will

Review annually. Revise immediately after: marriage, divorce, birth or adoption of a child, death of a named heir, significant change in assets, or change in state or country of residence.

Each revision should be a complete new will revoking all prior versions. Do not use codicils for Islamic wills.

Your Next Step

Write down the names of your Quranic heirs today. Your spouse, children, parents, siblings. Note which category each falls into. This takes 10 minutes and forms the foundation of your wasiyyah.

For understanding the shares each heir receives, read How Islamic Inheritance Law Works in Practice. For the charitable portion of your wasiyyah, read Sadaqah Jariyah as Strategic Giving.
