Islamic Will (Wasiyyah)
Why every Muslim with property should have a will, how far it may go, what comes before it and after it, and a practical checklist.
- Maximum bequest: one-third of the net estate (after funeral costs and debts).
- No bequest to someone who is already an heir, unless the other heirs agree after the death.
- A will is the tool for people who would not inherit: orphaned grandchildren, adopted or foster children, non-Muslim relatives, charities.
- Islamic wording is not enough on its own: your country’s law decides whether the document is enforceable.
What is a wasiyyah?
Wasiyyah (also written wasiyat or wasiya) means a bequest or instruction made during life that takes effect after death. It covers two things: a bequest of property (for example, a gift to a charity or to a grandchild) and instructions (funeral wishes, guardians for children, debts to be repaid). It is different from hibah, a gift given while you are alive, and from the faraid inheritance shares, which Allah fixed in the Quran and which apply automatically.
Is a will required in Islam?
“It is prescribed for you, when death approaches any of you, if he leaves wealth, that he make a bequest for parents and near relatives according to what is fair, a duty upon the righteous” (Quran 2:180).
Quran.com 2:180. Scholars explain that the verse was later regulated by the fixed inheritance shares (Quran 4:11-12), leaving the will for non-heirs and good causes.
Abdullah ibn Umar reported that the Prophet ﷺ said: “It is not right for any Muslim who has something to will to stay for two nights without having his last will written and kept ready with him.”

Scholars differ on whether a will is obligatory for everyone, but they agree it becomes obligatory if a person owes debts or has trusts and rights that others do not know about. It is strongly recommended for everyone with property or responsibilities, and especially before travel or surgery, or when ill.
Abu Hurairah reported that the Prophet ﷺ said: “When a man dies, his deeds come to an end except three: ongoing charity, knowledge from which people benefit, or a righteous child who prays for him.”
Source: Sahih Muslim 1631 · Sunnah.com. A bequest to a well, a masjid or the care of orphans is a way to leave ongoing charity (sadaqah jariyah).
The one-third limit
Sa’d ibn Abi Waqqas was ill in Makkah and asked the Prophet ﷺ whether he could will all of his property, then half. The Prophet ﷺ said no. Sa’d asked about one-third, and he said: “One-third, and one-third is much. It is better to leave your heirs well-off than to leave them poor, begging from people.”
Source: Sahih al-Bukhari 2742 · Sahih Muslim 1628 · Sunnah.com
So a Muslim may bequeath up to one-third of his estate (after debts and funeral costs) to non-heirs or to good causes. Many scholars recommend less than a third, particularly when heirs are in need. If the will goes beyond one-third, the excess only stands if the heirs, being adults of sound mind, agree after the death; their consent before death does not count. Charity from the one-third can be a lasting good deed; see the sadaqah calculator.
Worked example
| Item | Amount |
|---|---|
| Total estate (property, savings, valuables) | 100,000 |
| Minus funeral costs and debts | − 10,000 |
| Net estate | 90,000 |
| Maximum for the will (one-third) | 30,000 |
| Left for the heirs by faraid (at least two-thirds) | 60,000 or more |
The one-third is a ceiling on the net estate, not a target. Leaving less, such as a tenth, is perfectly valid and often wiser when the family is not well-off.
No bequest to an heir
The Prophet ﷺ said: “Allah has given everyone who has a right his right, so there is no bequest for an heir.”

The shares of the heirs are fixed by Allah, so a will cannot increase one heir’s share at the expense of the others, unless the other heirs agree after the death. The Quran also says bequests must be “without harm” to the heirs (Quran 4:12), so a will should never be used to cut family members out. Use our Islamic inheritance (Faraid) calculator to understand who inherits what.
Who a will is for
- Grandchildren whose parent died before the grandparent. Under classical faraid they are often excluded by their uncles and aunts. Some countries change this by law (for example, Section 4 of Pakistan’s Muslim Family Laws Ordinance 1961 gives orphaned grandchildren a share), but a bequest within one-third is the Islamic way to provide for them where the law does not.
- Adopted and foster children, who do not inherit by default.
- Non-Muslim relatives, who are not entitled to inherit but may receive a bequest.
- Charities, a masjid, a school or orphans.
The order: funeral, debts, will, then inheritance
| Step | What happens |
|---|---|
| 1 | Funeral and burial costs (see funeral and burial rites) |
| 2 | Debts, including unpaid dues to people and taxes; unpaid zakat and kaffarah according to the majority view (see note below) |
| 3 | The will, up to one-third, for non-heirs and good causes |
| 4 | The remainder is shared among heirs according to Quran 4:11-12 and 4:176 |
The Quran repeatedly says the shares are “after any bequest he may have made or any debt” (Quran 4:11-12). Although the verse mentions the bequest first, the Prophet ﷺ ruled that debt is settled before the bequest, and the majority of scholars act on this (Jami’ at-Tirmidhi 2122, graded hasan).
What to include in your will
- A declaration of faith and advice to your family to fear Allah and stay united.
- Debts and trusts you owe to people, with documents and who is owed. Also money others owe you.
- Unpaid religious duties: zakat, missed fasts and prayers, an unfulfilled Hajj; see missed prayers, Fidya and Kaffarah.
- Funeral wishes: simple burial, who will wash and pray; see Janazah prayer.
- Guardians for minor children and who manages their property.
- Charitable bequests within one-third and recipients, such as a masjid, water well or orphans.
- Names and details of non-heirs you wish to benefit, with exact amounts or percentages.
- An executor you trust, a backup executor, and where your documents and accounts are kept.
Pray for yourself and your family: see dua for the deceased, dua for parents and duas for family.
How to write an Islamic will: step by step
- List what you own and owe. Property, bank accounts, investments, business shares, gold, and every debt.
- Work out your heirs. Use the faraid calculator to see who inherits by default, so you know who is left out.
- Decide the bequest. Choose recipients among non-heirs and charities, staying within one-third of the net estate.
- Write the instructions. Debts, religious duties, funeral wishes, guardians and executor, in clear plain language.
- Sign it properly. Follow your country’s rules for signing and witnesses (below).
- Store it and tell your executor. A will nobody can find does not help your family.
- Review it after any major life change and every few years.
Making it legally valid
Requirements differ by country. As examples from published guides:
| Country | Typical requirements |
|---|---|
| United Kingdom | Written, signed by you, and witnessed by two independent adults who are not beneficiaries. Without a valid will, intestacy rules apply, which do not follow Islamic shares. |
| Pakistan | A written will with two adult Muslim witnesses is the usual practice; registration is optional but recommended. Heirs’ fixed shares still apply, and the one-third limit applies to non-heirs. |
| Singapore | The Muis wasiat guidance asks for a testator aged 21 or above, two Muslim male witnesses aged 21 or above who are not beneficiaries, and a named executor. |
| Other countries | Rules vary by state or province. Ask a local solicitor or attorney experienced in Islamic wills. |
Common mistakes to avoid
- Waiting. The hadith warns against letting even two nights pass.
- Willing to an heir (such as leaving the house to one son) without the other heirs’ consent after death.
- Going over one-third and assuming the heirs will agree.
- Leaving debts out. Unrecorded debts are the most common cause of family disputes.
- Vague wording, such as “give some to charity”, instead of named recipients and amounts.
- Ignoring local law, so the document is not enforceable in court.
- Never updating after a marriage, a birth, a death or a property purchase.
Frequently asked questions
Is a will compulsory in Islam?
Strongly recommended for anyone with property, and obligatory if you have debts or trusts that others do not know about (Sahih al-Bukhari 2738).
How much can I leave in my will?
Up to one-third of the net estate, to non-heirs or good causes. Less is better if your heirs are in need (Sahih al-Bukhari 2742).
Can I give more to one child in my will?
Not through the will. Shares are fixed, and there is no bequest to an heir unless the other heirs agree after your death. Gifts made fairly during life are a different matter and should be equitable among children.
Can I leave something to a non-Muslim relative?
Yes, through the will within the one-third limit. Non-Muslims do not inherit by default.
Can I leave my wife or husband more than their share?
A spouse is an heir, so the will cannot raise their share without the consent of the other heirs. You can provide for them during life through gifts or by arranging housing, and the heirs may agree to more after your death.
Do debts come before the will?
Yes. Debts and funeral costs are settled first, then the will, then the inheritance (Jami’ at-Tirmidhi 2122).
Can I leave property to my orphaned grandchildren?
Yes. They are often not heirs under classical faraid when an uncle or aunt is alive, so a bequest within one-third is the Islamic way to provide for them. Some countries, such as Pakistan, also give them a statutory share.
Is an oral will valid in Islam?
Scholars generally accept a will spoken clearly before reliable witnesses, but a written, signed and witnessed will avoids disputes and is usually required by courts.
Can I change my will?
Yes, at any time during life, as long as it remains within Islamic limits.
Does an Islamic will replace a legal will?
No. Your Islamic will should be written so that it also satisfies local legal requirements, otherwise a court may disregard it.
