Islamic Inheritance Calculator (Faraid) — Quran 4:11
حاسبة الفرائض — قسمة التركة الشرعية
Calculate Islamic inheritance shares based on the Quran (4:11–12, 4:176) and Sunnah. Enter the estate value and select the surviving heirs.
Faraid is a complex scholarly discipline. This tool covers common scenarios based on the Sunni consensus. Always verify with a qualified Islamic scholar (مفتي) before distributing any estate — especially in complex cases involving multiple wives, grandparents with siblings, or missing heirs.

Understanding Faraid
Quranic Foundation
Faraid shares are derived directly from the Quran (4:11–12, 4:176) — the only place in the Quran where Allah specifies precise numerical fractions. The Prophet ﷺ called inheritance knowledge 'half of all knowledge.'
'Awl & Radd
'Awl (عَوْل) applies when fixed shares exceed 100% — all shares reduce proportionally. Radd (رَدّ) applies when shares total less than 100% with no residuaries — surplus returns to non-spouse fixed sharers.
Who Cannot Inherit
A murderer of the deceased, a non-Muslim heir (from a Muslim deceased), and a divorced spouse cannot inherit. A child in the womb inherits if born alive. Adopted children are not Faraid heirs (but can receive a bequest up to 1/3).

Frequently Asked Questions
What is Faraid (Islamic inheritance)?+
Faraid (الفرائض) is the Islamic law of inheritance derived from the Quran (4:11-12, 4:176) and the Sunnah. It defines precise fractional shares for specific heirs and the order in which they inherit. The Prophet ﷺ said: 'Learn the laws of inheritance and teach them, for it is half of knowledge.' (Ibn Majah)
What is the difference between fixed sharers and residuaries?+
Fixed sharers (أصحاب الفروض) receive a predetermined fraction of the estate — e.g., a wife receives 1/8 when children are present. Residuaries (العصبات) receive what remains after fixed sharers are paid — sons, brothers, and the father (when no children) are residuaries.
What is 'Awl (عَوْل)?+
'Awl applies when the total of fixed shares exceeds the estate (more than 100%). In this case, all fixed shares are reduced proportionally so they fit within the available estate. This was the ruling of Umar ibn al-Khattab (RA) accepted by the Companions.
What is Radd (رَدّ)?+
Radd is the opposite of 'Awl — when the fixed shares don't add up to the full estate and there are no residuaries, the surplus is returned to the fixed sharers proportionally (excluding spouses in the Hanbali/Shafi'i view). This calculator applies Radd to all non-spouse sharers.
What is Hajb (blocking)?+
Hajb means one heir prevents another from inheriting. Hajb Hirman (complete blocking) removes an heir entirely — e.g., a son blocks brothers. Hajb Nuqsan (partial blocking) reduces a share — e.g., children reduce the mother from 1/3 to 1/6. A closer relative always blocks a more distant one.
Does a daughter block brothers?+
No. A daughter does not block brothers. However, a son blocks brothers (full blocking). A daughter combined with a full sister makes the sister a residuary (asabiya ma'a al-ghair), taking what's left after daughters' fixed shares.
How are debts and bequests handled?+
Before Faraid shares are calculated, the estate must first pay: (1) funeral expenses, (2) the deceased's debts, (3) any bequest (wasiyya) — which is capped at 1/3 of the net estate and cannot benefit a legal heir. This calculator works on the net distributable estate after these deductions.
Can heirs agree to a different split?+
After the Faraid shares are correctly calculated, adult heirs may agree to redistribute among themselves voluntarily (Takhaaruj). However, this does not change the legally mandated Faraid shares — it is a separate voluntary agreement.
