Shariah Rule: A Muslim may only bequeath up to 1/3 of the net estate to non-heirs (charities, friends, non-Muslim relatives). The remaining 2/3+ is distributed to legal heirs (Faraid) and cannot be overridden by a will. Bequests to legal heirs require consent of all other heirs.

What is a Wasiyyah (Islamic Will)?

A Wasiyyah is an Islamic will or testament. It is the voluntary bequest a Muslim can make to direct up to one-third of their net estate to recipients of their choice โ€” charities, friends, institutions, or non-Muslim relatives who would not inherit under Faraid law.

The Prophet Muhammad ๏ทบ said: "It is the duty of a Muslim who has something to bequest not to let two nights pass without including it in his written will." (Bukhari & Muslim)

The 1/3 Rule (Wuแนฃลซl al-Thuluth)

A Muslim may not bequest more than one-third of their net estate (after debts and funeral expenses) to non-heirs. This protects the rights of legal heirs (Faraid). Bequests to legal heirs themselves require the unanimous consent of all other heirs.

Frequently Asked Questions

Can I leave everything to my spouse?
No โ€” under Islamic law, a spouse receives a fixed share (1/4 or 1/8 depending on children). You cannot override Faraid using a will. However, if you are in a non-Muslim country, you may wish to consult both a scholar and a solicitor about how Islamic and civil law interact in your jurisdiction.
Do I need a lawyer as well?
Yes โ€” in most countries a will must meet legal requirements (witnesses, notarisation) to be legally binding. An Islamic will should ideally be both Shariah-compliant and legally valid under your country's law. Seek both an Islamic scholar and a local solicitor/attorney.
What if I have no heirs?
If you have no Faraid heirs, the entire estate can be directed via Wasiyyah. In this case the 1/3 restriction typically does not apply and the full estate may go to charitable causes, according to many scholars.
Can non-Muslim relatives inherit?
Under classical Faraid law, non-Muslim relatives do not inherit. However, you can include them within your Wasiyyah bequest (up to 1/3 of net estate). This is a valid and widely accepted approach.
