Faraid, the fixed system of Quranic inheritance shares, leaves relatively little room for personal discretion, and this is by design. But Islamic law does provide one specific, limited mechanism for a person to direct part of their estate according to their own wishes: the wasiyyah, or Islamic bequest. Understanding exactly what it can and cannot do prevents both under-using it and, more commonly, assuming it allows more flexibility than it actually does.
This is general information to help families understand the concept, not a fatwa or legal advice. Any specific wasiyyah should be confirmed with a qualified Islamic scholar.
What a wasiyyah actually allows
A wasiyyah lets a Muslim direct up to one-third of their net estate, after debts and funeral expenses, to a person or cause of their choosing, outside the fixed Faraid distribution. This might be a charitable donation, support for a non-heir such as a friend or a more distant relative, or a specific bequest tied to a cause the person cared about. The remaining two-thirds, at minimum, must still be distributed according to the fixed Quranic shares among the eligible heirs.
Why the one-third limit exists, and why it is strictly enforced
The limit exists specifically to protect the fixed inheritance rights of Quranic heirs, spouse, children, parents, from being eroded by a testator's personal preferences. Without this limit, a wasiyyah could effectively be used to disinherit an heir the Quran specifically protects, which is precisely what the system is designed to prevent. Scholars and Sharia courts generally will not enforce a wasiyyah that exceeds one-third without the unanimous consent of all the heirs, given after the person's death.
The rule against bequeathing to an existing heir
A wasiyyah generally cannot be used to give an additional amount to someone who is already a Quranic heir, for example, leaving an extra sum to one son beyond his fixed Faraid share. This would functionally alter the prescribed shares, which the wasiyyah mechanism is not permitted to do. It exists to direct assets outside the heir structure, not to adjust shares within it.
Common, legitimate uses of a wasiyyah
- A charitable donation to a mosque, school, or cause the person supported during their life.
- Support for a friend, a more distant relative who is not a Quranic heir, or a caregiver.
- A specific bequest tied to a particular purpose, such as funding a relative's education.
Making a wasiyyah valid and enforceable
A wasiyyah should be made in writing, clearly specifying the amount or asset involved and the recipient, and ideally confirmed with a scholar or Sharia court familiar with the specific rules that apply in the relevant jurisdiction. It should also be considered alongside a complete, accurate list of the estate's total assets, since the one-third limit is calculated against the net value of everything owned, not against a single asset in isolation.
How Remayn helps
Remayn does not calculate wasiyyah limits or resolve religious questions, that role belongs to a scholar or Sharia court. What Remayn ensures is that the total estate a wasiyyah's one-third is calculated against is actually known and complete: every bank account, property, and asset registered in one place, so that both the fixed Faraid shares and any wasiyyah can be applied to an accurate picture, rather than an incomplete guess.
