Will Calculator
Plan the distribution of your estate in accordance with Islamic inheritance law (Farāʾiḍ).
How an Islamic Estate Is Distributed
The Shariah sets a fixed order. This calculator walks through all four steps.
- 1Funeral expenses
Reasonable burial costs come out of the estate first.
- 2Debts
All debts are settled — loans, unpaid mahr, and unpaid zakah.
- 3Wasiyyah (bequest)
Up to one-third may be left to charity or non-heirs. Heirs already receive fixed shares, so a wasiyyah cannot be made to them.
- 4Heirs (Farāʾiḍ)
The remainder is divided among your heirs in the fixed shares set by the Qur'an.
Your School of Thought
The four schools agree on most shares, with small differences in a few rarer cases.
Your Estate
Everything you personally own. For jointly-owned assets, include only your share.
Funeral Costs & Debts
Settled before anything is distributed. Debts owed to Allah — unpaid zakah, kaffārah — are treated as debts too.
Wasiyyah (Bequest)
You may leave up to one-third of your net estate to charity or to anyone who is not an heir — a sadaqah jāriyah that keeps benefiting you after death.
Your Surviving Family
Select the relatives who would survive you. The calculator applies the fixed shares and works out who is excluded (ḥajb) automatically.

Siblings only inherit when not blocked by your children, grandsons, or father — the calculator handles this.

A bequest to your masjid is a sadaqah jāriyah that continues after you.
This calculator is an educational estimate following the rulings of your selected school of thought. It does not cover every relative or situation (uncles, nephews, and more distant kin are not included), and it is not a legal will: to be enforceable in Alberta your will must meet provincial requirements. Please consult a qualified scholar and an estate lawyer.
