Islamic Inheritance Calculator الفرائض
Shares of each heir according to the Quran and Sunnah, with the rulings of the four Sunni schools.
How it works
Before distribution
Funeral costs are paid first, then debts, then bequests (wasiyyah) of up to one-third to non-heirs. The remainder is divided among the heirs.
Fixed shares and residue
Heirs with fixed shares (ashab al-furud) — such as spouses, parents and daughters — take first; the residue goes to the nearest male agnates ('asabah).
'Awl and radd
If fixed shares exceed the estate, all are reduced proportionally ('awl). If they fall short and there is no residuary heir, the surplus returns to the fixed-share heirs except the spouse (radd).
Not covered
Distant relatives (dhawu al-arham), missing persons, unborn children, simultaneous deaths and heirs barred by difference of religion or homicide require a scholar.
Frequently Asked Questions
Is the result valid in every country?
The shares follow the Quran, Sunnah and the four schools, which apply worldwide. Some countries modify them by law — for example Bangladesh and Pakistan give orphaned grandchildren their deceased parent's share (Muslim Family Laws Ordinance 1961). Check your local law and a qualified scholar.
Why does a son receive twice a daughter's share?
The Quran sets this ratio (An-Nisa 4:11). Scholars explain that men carry the financial obligations of dowry, housing and maintenance of the family, while a woman's share is hers alone.
Can I leave more than one-third by will?
A bequest above one-third, or any bequest to an heir, needs the consent of the other heirs.
Which school should I choose?
The school followed in your country or by your family. The schools agree on most cases and differ mainly on the grandfather with siblings, the Mushtarakah case and the paternal grandmother with the father.
