If a Muslim passes away in the United States without a will, the distribution of their assets is not decided by Islamic law. It is decided by state law.
That distinction is critical. In the U.S., when someone dies without a will, their estate goes through what is called intestate succession. Each state has its own rules, but the core idea is the same: the government determines who inherits and in what proportions.
For Muslim families, this often leads to outcomes that do not align with Islamic inheritance principles.

Why this is a real problem
Islamic inheritance law (faraid) is structured and specific. It assigns fixed shares to certain heirs and is not meant to be overridden by personal preference or convenience.
U.S. estate law works very differently. It prioritizes individual freedom, allowing people to distribute their assets however they choose through a will. But when there is no will, the system falls back to a default structure that has no connection to Islamic rules.
A recent academic study in the journal Asy-Syir’ah highlights this exact tension. It explains that Muslim families in the United States face ongoing difficulty reconciling Islamic inheritance obligations with a legal system that is not designed to enforce them.
What actually happens to the estate
When there is no will, the probate court follows state intestacy laws. These laws typically prioritize spouses, children, and close relatives, but the distribution structure can differ significantly from faraid.
For example, state law may allow a surviving spouse to receive a much larger portion of the estate than they would under Islamic inheritance. In other cases, certain relatives may inherit even though they would not be included under faraid, or vice versa.
The key point is that the system is not trying to follow Islamic rules. It is applying a completely different framework.
Why many Muslim families end up here
One of the most important findings from the research is that many Muslims in the U.S. simply do not create a will at all. As a result, their estates are distributed according to state law by default, even if that outcome conflicts with their beliefs.
There are a few reasons for this. Some people assume they are too young or do not have enough assets to justify estate planning. Others assume their family will “figure it out.” And many are not aware that the default system will not account for Islamic inheritance at all.

The consequences of not having a plan go beyond just distribution percentages.
First, there is legal complexity. Probate can take time, and without clear instructions, it can slow down even further.
Second, there is family tension. When expectations are unclear, disagreements can arise between heirs, especially in already difficult emotional circumstances.
Third, there is the religious concern. For many families, the biggest issue is not just who gets what, but whether the estate was handled in a way that aligns with Islamic obligations.
For a full breakdown of what should be in place, see Islamic Estate Planning Checklist.
Can a will fix this?
A properly structured estate plan can significantly reduce these risks, but it has to be done carefully.
The same study discusses how tools like Shariawiz are designed to help Muslims create legally valid documents that incorporate Islamic inheritance principles. These platforms use structured inheritance calculations and integrate them into wills and estate plans that can function within U.S. law.
This is an important shift. Instead of choosing between religious principles and legal compliance, families can start to align both.

Why this matters more than people think
Estate planning is often treated as something to deal with later. But the reality is that the default system is already in place. If no action is taken, the outcome is effectively pre-determined by state law.
As Muslim families in the U.S. continue to build wealth, this issue becomes more significant. Homes, investment accounts, businesses, and retirement savings all need to be accounted for.
Final thoughts
If a Muslim dies without a will in the United States, their estate will be distributed according to state law, not Islamic inheritance law.

That is not a small detail. It is the difference between a system based on individual choice and one based on defined obligations.
The good news is that this can be addressed. With the right planning, it is possible to create a structure that works within U.S. law while reflecting Islamic principles. But it does not happen automatically. It requires intention, understanding, and the right tools.
