A few years into this work, I stopped being surprised by a particular sentence. It usually shows up about twenty minutes into a first meeting, after we’ve talked through the house, the retirement accounts, the kids. Someone leans back, gets a little reassured look on their face, and says: “Honestly, if I never get around to a will, it’ll just get divided the Islamic way anyway, right?”
I wish that were true. It would make my job a lot easier. But in Illinois, dying without a will does not hand your estate over to faraid, the Quranic system of inheritance. It hands it over to the State of Illinois and a statute called the Probate Act. And those two do not agree with each other.
Let me walk you through both, because the distance between them is more or less the reason my law firm exists.
Also before you start digging into this, just a fair warning, some of what you may read will either hurt your head, or sound confusing and it’s supposed to. The good news is I’m here to have a real conversation with you about it when you book a call with me. So without further ado..
What Illinois actually does when you die without a will
When an Illinois resident passes away without a valid will, the state applies what’s called intestate succession. The rules are mechanical. They don’t ask about your faith, your intentions, or the conversation you kept meaning to have with your spouse last Ramadan. They just run.
If you’re married with children, Illinois cuts your estate in half. Your surviving spouse takes one half, and your children split the other half equally, “per stirpes,” which means if one of your children has already passed, that child’s share drops down to their own kids. If you’re married with no children, your spouse takes everything. If you have children but no surviving spouse, the children take it all equally.
Sit with what that means for a moment.
A son and a daughter inherit the exact same amount. A surviving spouse takes a flat half, no matter what the Quran would have set aside for her. Your parents, who in Islam often have a fixed claim, typically receive nothing while a spouse or children survive. The whole estate gets divided with zero reference to the fixed shares a Muslim spends a lifetime intending to honor.

What faraid does instead
Islamic inheritance runs on a completely different logic. Rather than splitting things into neat halves between “spouse” and “kids,” it assigns fixed fractional shares to specific heirs, and those fractions shift depending on exactly who survives you.
A wife receives one-eighth of her husband’s estate if he leaves children, and one-quarter if he doesn’t. A husband receives one-quarter of his wife’s estate if she leaves children, and one-half if she doesn’t. A single daughter is a Quranic sharer entitled to one-half; two or more daughters share two-thirds between them. Where there are both sons and daughters, the well-known rule applies that a son receives the share of two daughters. Parents frequently take a one-sixth share each. Only after those fixed sharers are paid does whatever remains (the residue) pass to the agnatic relatives, what the jurists call the asaba.
You don’t need to be a scholar to notice that none of this looks like “half and half.” The Illinois default and the Islamic obligation land in different places in nearly every family I’ve ever sat across from.
Take a simple case. A father passes away leaving a wife, a son, and a daughter. Under Illinois intestacy, the wife takes one half, and the son and daughter split the other half equally, a quarter each. Under faraid, the wife takes one-eighth, and the remaining seven-eighths is divided between the children so that the son receives twice the daughter’s share. Same family, same assets, two very different outcomes. Multiply that by every Muslim family in the state, and you start to see why simply trusting the default is such a gamble.
The quiet trap of “I’ll just let the law handle it”
Here’s the part that genuinely worries me. A lot of Muslims assume that doing nothing is the safe, neutral, even pious option: that if they never sign anything, God’s plan simply takes over by default. The truth is the reverse. In Illinois, doing nothing means the Probate Act takes over, and the Probate Act was not drafted with the Quran anywhere in view.
I’ve sat with widows who learned, in the worst week of their lives, that the state’s arithmetic handed them a different share than their husband had always assumed they’d get. I’ve watched adult children receive equal portions a parent never intended, while a grandparent who should have had a fixed sixth received nothing at all, because intestacy simply doesn’t reach the same people the same way. None of it was anyone’s fault. It was just the default, running its course.
And there’s a wrinkle most people miss: some of your biggest assets may not even be governed by intestacy or by your will. Life insurance, a 401(k), an IRA: those pass by beneficiary designation. If the form on file names the wrong person, or names no one, that money moves on its own track entirely, faraid or not. I’ve seen a single outdated beneficiary form quietly undo an otherwise careful plan.

How you close the gap
The good news is that Illinois actually hands you the tools to override its default completely. A properly drafted will, and very often a trust working alongside it, lets you direct your estate according to faraid while satisfying every box the Illinois courts insist on: the right signatures, the right witnesses, the right language. We build the Islamic distribution into a document the probate court will genuinely enforce, and we line up those beneficiary forms so they point the same direction. That’s the real marriage of the two systems, and it only ever happens on purpose.
If you take one thing away from this, let it be this: silence is not a Shariah-compliant estate plan. Silence is an Illinois one. The choice between the two belongs to you, but only while you’re still here to make it.
