How Islamic Inheritance Actually Works in Australia

By Wasiyya Editorial • 4 min read

At its core, Islamic inheritance law is a faith-based framework built to distribute wealth fairly, protect dependants, and preserve family ties after death. For Australian Muslims, the real question isn’t “what are the rules?” — it’s “can these rules actually hold up here?”

 

The answer is yes. You don’t have to choose between your faith and Australian law. Because Australian legislation — including the Succession Act 2006 (NSW) and the Wills Act 1968 (ACT) — grants broad “testamentary freedom,” you’re legally entitled to distribute your estate according to Islamic principles, provided your will is drafted and witnessed correctly.

 

Understanding how the mechanics actually work is the first step to getting both right.

 

The Two Pillars of an Islamic Will

A valid Islamic will splits your net estate — after debts and funeral costs are paid — into two parts:

 

1. The Wasiyyah (discretionary bequest). You may allocate up to one-third of your estate to anyone who wouldn’t automatically inherit under Islamic law. This is commonly used for charitable endowments (Sadaqah Jāriyah), mosques, or to provide for non-Muslim relatives, adopted children, or step-children.

 

2. The Farāʾiḍ (fixed shares). The remaining two-thirds or more is distributed to your eligible blood relatives and spouse according to the formulas set out in the Quran and Sunni consensus (ijmāʿ).

“Islamic law and Australian public policy agree on disqualification, someone who unlawfully causes the testator’s death is disqualified from inheriting outright.”

How Farāʾiḍ Actually Divides an Estate

Farāʾiḍ functions like a precise rule engine — it sorts your family into categories and applies strict priority rules to determine who receives what.

 

  1. Fixed-share heirs (Dhawū al-Furūḍ)

These heirs are guaranteed a specific fractional share. The group includes your spouse, parents, and daughters, among others, and shares shift depending on who else survives you. A surviving wife, for instance, receives 1/4 of the estate if there are no children, dropping to 1/8 if the deceased leaves descendants (Quran 4:12).

 

  1. Residuary heirs (ʿAṣabah)

Whatever remains after fixed shares are paid goes to residuary heirs, typically male-line relatives. A surviving son is the primary residuary heir. When a son and daughter inherit together, they share the residue with the son receiving twice the daughter’s portion (Quran 4:11) — a ratio tied to the financial maintenance obligations placed on men under classical Islamic law, not a statement about relative worth.

 

  1. The rules of exclusion (Hajb)

Islamic inheritance runs on proximity: closer relatives block more distant ones from inheriting at all. For example:

  • Descendants block siblings. If you leave behind a child, or a son’s son, your siblings — full, paternal, or maternal — are excluded entirely.
  • A father blocks siblings and grandfathers. A surviving father excludes the deceased’s paternal grandfather and all siblings from the inheritance.
  1. Disqualification

Islamic law and Australian public policy agree here: someone who unlawfully causes the testator’s death is disqualified from inheriting outright. They’re treated as though they died before the testator, and their share is redistributed among the remaining eligible heirs — mirroring Australia’s own forfeiture rule.

 

When the Numbers Don’t Add Up

Because family structures vary, the fixed fractions don’t always sum neatly to the whole estate. Classical jurisprudence — followed by the majority (jumhūr) of Sunni schools — has established fixes for both directions:

 

Shares exceed the estate (ʿAwl). If the prescribed shares add up to more than 100%, every heir’s share is reduced proportionally so the estate isn’t overdrawn.

 

Shares fall short (Radd). If a surplus remains after fixed shares are paid and no residuary heir exists to claim it, that surplus is returned proportionally to the eligible blood heirs. Spouses are traditionally excluded from this return, though scholars have addressed how to handle cases where a spouse is the only heir remaining.
