A wasiat is a will made under Muslim law. It lets a Muslim direct how part of their estate is dealt with after death, within the limits that Muslim law sets. The general position in Singapore is that a Muslim may bequeath up to one-third of the estate to non-heirs by wasiat, while the remainder is distributed among the heirs under faraid, the system of fixed-share inheritance in Muslim law.

This article explains, in general terms, what a wasiat is, how it fits with faraid, and how related tools and assets sit around it. It is written with respect for a religious subject, and it is general information only: it cannot interpret Islamic law or apply it to your family. MUIS (the Islamic Religious Council of Singapore) and the Syariah Court are authoritative on how these rules work in Singapore. Our Syariah family law overview sets the wider context.

What a wasiat is

A wasiat is a Muslim’s testamentary instrument, the means by which they set out wishes that take effect on death, within Muslim law. It is not a free hand over the whole estate. Muslim law shapes both how much may be disposed of by wasiat and to whom, which is what distinguishes it from a civil will where, subject to some limits, a person may generally leave their estate as they choose.

Because those limits are a matter of religious law, a wasiat needs to be made correctly to be valid and to do what you intend. That is a reason to have it prepared with proper guidance rather than adapted from a general template. A civil will and a wasiat are different instruments serving people in different legal positions; if you are curious about the civil side for comparison, our wills and probate hub covers it, but a Muslim’s estate is governed by the Muslim law framework described here.

The one-third position and faraid

The general rule most people encounter first is the one-third position: a Muslim may bequeath up to one-third of the estate to non-heirs by wasiat. The purpose is to allow some flexibility, for example to benefit someone who would not otherwise inherit, or a charitable cause, without displacing the fixed shares that Muslim law reserves for the heirs.

The remainder of the estate, and the portion not validly disposed of by wasiat, is distributed under faraid. Faraid allocates fixed shares among the eligible heirs according to defined rules. A wasiat therefore operates within the faraid framework rather than overriding it. There are conditions and nuances to the one-third position, including how it interacts with the heirs’ entitlements, so treat this as the general shape of the rule, not the last word. How faraid distributes an estate is set out in our guide to Muslim inheritance and faraid in Singapore. For how it applies to your own family, MUIS is the authority.

A wasiat is not the only planning instrument in Muslim law. Two others are commonly mentioned alongside it, and it helps to know what they are, described generally.

Hibah

Hibah is a gift made during a person’s lifetime. Because it takes effect while the giver is alive rather than on death, it operates differently from a wasiat, and it can be used in planning to pass particular assets to particular people. Like everything here, it has its own requirements for validity.

Nuzriah

Nuzriah is a form of vow or pledge recognised in Muslim law, which can feature in estate planning. Its use and effect are technical and are matters for religious and legal authority.

These are general descriptions, offered so you know the terms exist and can ask about them, not scholarly rulings on how to use them, and not settled positions you should act on from a web page. Whether hibah, nuzriah or a wasiat, or some combination, suits your situation is exactly the kind of question to put to MUIS or a qualified adviser, because the tools interact and the details govern the outcome.

What falls outside the estate

One of the most important practical points in Muslim estate planning is that some of your most valuable assets may not form part of the estate that a wasiat and faraid deal with at all.

  • CPF savings. Your CPF money is generally distributed according to your CPF nomination on death, made through the CPF Board, rather than through your will or faraid. If you have made a nomination, that is what governs your CPF; if you have not, CPF applies its own process. Either way, it sits outside the estate.
  • Jointly held property. Property held in joint tenancy typically passes to the surviving joint owner automatically by survivorship, outside the estate. Whether your property is held that way or as a tenancy in common makes a real difference, and our guide to joint tenancy versus tenancy in common explains the distinction.

The consequence is that a wasiat, however carefully made, does not reach these assets. People sometimes assume their will covers everything and are surprised to find that the flat and the CPF are dealt with by separate mechanisms. Getting the whole picture aligned, meaning the wasiat, the CPF nomination and how property is held, is central to planning that actually works.

Where authority lies

The rules in this article, such as the one-third position, faraid, hibah and nuzriah, are matters of Muslim law, and their correct application is for religious and legal authority. This page is a general orientation. It is not a ruling, it does not interpret Islamic law, and it should not be used as the basis for drafting a wasiat.

MUIS and the Syariah Court are authoritative on how these rules apply in Singapore. For the civil mechanics that sit alongside a wasiat, such as making a valid document and understanding probate generally, our guide to will writing in Singapore gives background, but a Muslim’s estate planning should be built on the Muslim law framework and confirmed with the proper authorities.
