A Muslim family member dies. The grieving starts immediately, and so does the question nobody wants to raise: who gets what? In Islamic law, this question has a precise answer. The Quran specifies exact fractional shares for most heirs. The system is called faraid, and it has governed Muslim inheritance for over 1,400 years. The problem is that U.S. law doesn't know faraid exists.
If a Muslim dies in the U.S. without a properly structured will, the state's intestate succession laws take over. Those laws reflect American legal norms, not Quranic inheritance rules. The shares often come out differently. In some cases, significantly differently. This guide explains what Islamic inheritance law requires, where U.S. law conflicts with it, and what your family needs to do to make sure distribution follows Quran.

What is faraid?
Faraid is the Islamic law of inheritance. It comes directly from Surah An-Nisa (4:11-12, 4:176), which lays out specific fractional shares for specific relatives. Unlike a conventional will where the deceased can leave assets to anyone in any proportion, faraid is largely fixed by revelation. The shares shift based on which relatives survive, but the basic framework is non-negotiable in Islamic jurisprudence.
Some key rules: a spouse gets a fixed share (one-quarter if there are children, one-half if there are none, from the husband's estate; one-eighth or one-quarter from the wife's estate). Parents each get one-sixth if children survive. Daughters get half what sons receive in most cases. Non-Muslim relatives receive nothing under faraid, and a Muslim cannot inherit from a non-Muslim under strict faraid. Many scholars acknowledge that American Muslims live in a different legal environment and some rulings may need scholarly guidance for specific family situations.
How U.S. intestate law conflicts with faraid
Every state has intestate succession laws: rules for distributing assets when someone dies without a valid will. These rules vary by state, but most prioritize spouses and children equally regardless of gender, treat step-children and biological children differently than Islamic law does, and do not recognize religious inheritance rules at all. If a Muslim dies intestate in Texas, for example, state law controls the distribution, and it will not follow faraid.
Even with a will, U.S. courts will not enforce a distribution that violates certain legal constraints, such as spousal elective share rights. Many states give a surviving spouse the right to claim a percentage of the estate even if the will says otherwise. This can affect faraid calculations significantly, especially in states with large elective share percentages. An Islamic estate planning attorney can navigate these conflicts; this is exactly where ShariaWiz specializes.
The fixed shares: who gets what
Here are the basic faraid shares in the most common scenario (a married man with children who predeceases his spouse): the wife receives one-eighth of the estate. The remainder goes to children, with sons receiving twice the share of daughters. Parents, if alive, each receive one-sixth off the top before the remainder is divided. This is the baseline. It shifts substantially based on who survives and who does not.
Where it gets complicated: if there are no children, the parents' shares increase. If there are no parents and no children, siblings may inherit. If the deceased leaves behind a large extended family, the calculation requires someone trained in faraid to do correctly. Online faraid calculators (HalalWallet has a faraid calculator guide that explains how to use them) can help, but they're not a substitute for legal documentation.
How to make Islamic inheritance enforceable in the U.S.
The only way to ensure faraid is respected in the U.S. is through a properly executed Islamic will. This is a legal document, drafted under your state's will requirements, that explicitly distributes assets according to faraid. U.S. courts will enforce it if it's valid under state law and does not violate mandatory legal constraints (like spousal elective shares in some states).
For straightforward family situations, a well-drafted Islamic will from a reputable platform may be sufficient. For complex situations, including blended families, business assets, non-Muslim heirs, or estates above roughly $1 million, you need an attorney. ShariaWiz offers both attorney-drafted Islamic wills and consultations that address faraid in the context of U.S. law. They're the strongest option available for Muslims who want both Islamic compliance and legal enforceability in the same document.
What about wasiyyah? (The one-third exception)

Islamic law allows a Muslim to leave up to one-third of their estate through wasiyyah, a bequest that functions more like a conventional will. This one-third can go to anyone the deceased wants, including non-Muslim relatives, charities, or friends, as long as it does not go to a faraid heir who is already receiving their Quranic share. The other two-thirds must follow faraid.
This is a meaningful planning tool for American Muslims who want to leave something to a non-Muslim spouse, a step-child, or a cause they care about. Many Muslim families use this one-third to give to Islamic charities as sadaqah jariyah, or to provide for people in their lives who would otherwise receive nothing under faraid. See our article on wasiyyah for a full explanation of how this works and how to structure it.
Common mistakes Muslim families make with inheritance
The most common one is dying without a will and assuming family members will sort it out fairly. They rarely do, and even when they want to, U.S. probate law may prevent a private family settlement from overriding intestate distribution rules.
Second most common: assuming an old will is still valid. Family situations change. Children are born. Divorces happen. Assets are acquired. A will written in 2015 may not reflect current faraid correctly. Wills should be reviewed after every major life event. Third: thinking a basic online will covers Islamic requirements. Many general will platforms do not know faraid and will not prompt you to address it. Use a platform or attorney that knows Islamic estate law.
Who should get professional help
For simple situations, an Islamic will from a reputable platform with faraid built in may be enough. For anyone with blended families, business interests, real estate in multiple states, non-Muslim heirs, or estates large enough to trigger estate tax considerations, get an attorney. ShariaWiz is the best option on the market for this combination of Islamic knowledge and legal expertise. For a broader comparison of Islamic will platforms, see ShariaWiz vs MyWassiyah vs MinaWill.
Bottom line
Faraid is not optional in Islamic jurisprudence. If you want your estate distributed according to the Quran, you need a properly drafted Islamic will executed under your state's legal requirements. Without it, U.S. intestate law decides who gets what, and it will not follow Quranic shares. Start with the HalalWallet estate planning hub for resources, and get professional help from ShariaWiz if your situation involves any complexity.
Frequently asked questions
Is faraid legally enforceable in the U.S.? Yes, if it is incorporated into a valid will under your state's requirements. U.S. courts will enforce wills that follow Islamic inheritance rules as long as they do not violate mandatory state law provisions. An attorney familiar with Islamic estate planning can make sure your will is both Islamically correct and legally valid.
What if my family refuses to follow faraid after I die? If you have a legally valid Islamic will, they cannot override it without going to court and winning a will contest. The will controls. Without a will, there is nothing to enforce, and family members who disagree can each claim their state law share.
Do daughters really inherit half of what sons receive? Under classical faraid, yes, in most scenarios. This is a Quranic rule. Scholars have debated its application in the modern context, but it remains the established position in all four major schools of Islamic law. If you have concerns about how this applies to your family, a consultation with an Islamic estate attorney is the right move.

Can I use the one-third wasiyyah to leave more to a daughter who I feel will need more support? Generally no: wasiyyah cannot go to faraid heirs. It is designed for people outside the faraid system. However, you can make gifts to family members during your lifetime, which is a different category. Speak with an Islamic estate attorney if you want to provide additional support to a specific heir.
Do I need a separate Islamic will or can I add Islamic inheritance instructions to a regular will? You can incorporate faraid into a standard U.S. will, but it needs to be drafted carefully to comply with both Islamic requirements and state law. Using a platform or attorney that specializes in Islamic wills is much safer than trying to add Islamic clauses to a generic document.
