Canadian law lets you leave everything to charity. Islamic law caps the bequest at one third of the net estate, and the excess is only valid if the heirs consent after death.
The Canadian position
Testamentary freedom in Canada is broad. A gift of the entire estate to a registered charity is enforceable, and generates a donation tax credit on the final return that can materially reduce tax.
The Islamic position
The one-third ceiling comes from the hadith of Sa'd ibn Abi Waqqas, who wished to leave two thirds and was limited to one third, with the Prophet ﷺ adding that 'one third, and one third is a lot.'
A bequest beyond one third is not void outright — it takes effect to one third, and the remainder depends on the heirs consenting once the estate falls due.
All four Sunni schools apply the one-third cap and require heirs' consent for anything beyond it. The recognised difference concerns timing: consent given before death is generally not binding in the majority view.
What to do about it
- Decide the charitable amount as a fraction of the net estate, not a fixed dollar figure.
- Name registered Canadian charities so the estate can claim the donation credit.
- If you want to exceed one third, discuss it with your heirs and with a scholar.
