Calculate Islamic inheritance shares according to classical Faraid rules, including fixed shares, residuary heirs, and the one-third bequest limit.
Distributable estate = Total assets − funeral expenses − debts − wasiyyah (max 1/3). Fixed shares (furud) are allocated first; the remainder passes to the asabah.
A man leaves $300,000 net, survived by a wife, one son and one daughter. The wife takes 1/8 = $37,500. The residue of $262,500 splits 2:1 between son and daughter — $175,000 and $87,500.
In order: funeral and burial expenses, then all outstanding debts (including unpaid mahr and zakat), then any wasiyyah of up to one-third of what remains. Only the balance is divided by Faraid shares.
Based on the hadith of Sa'd ibn Abi Waqqas, where the Prophet ﷺ limited his bequest to a third and said 'a third, and a third is much.' Anything above a third requires the consent of all adult heirs.
No — the general rule is 'no wasiyyah for an heir.' A bequest can only go to non-heirs (charities, adopted children, non-Muslim relatives) unless the other heirs consent after death.
One-eighth if the deceased left children, one-quarter if not. Where there are multiple wives, that single share is divided equally among them.
The 2:1 residuary ratio pairs with the male's non-negotiable financial obligations under Shariah — maintenance of wife, children, and needy relatives — while a woman's inheritance and earnings remain entirely her own property.
'Awl applies when the fixed shares exceed the estate, so all shares are reduced proportionally. Radd is the reverse — leftover residue with no asabah is returned proportionally to the fixed-share heirs (excluding a spouse in most schools).
No. Faraid contains many edge cases — grandparents, siblings under different schools, missing heirs, blocked heirs (hajb). Use this as an estimate and confirm with a qualified mufti or Shariah-compliant estate lawyer.
