?What is the Warasat — Islamic Inheritance Calculator (Full Faraiz)?

The Warasat (Islamic Inheritance) Calculator is the most comprehensive implementation of classical Sunni Faraiz (inheritance science) on the open web. It distributes a deceased Muslim's estate across every category of heir mentioned in Quran 4:11, 4:12, and 4:176 — spouse, children, son's children (when the son has predeceased), parents, paternal/maternal grandparents, and three categories of siblings (full, consanguine, uterine). Madhhab selection (Hanafi, Maliki, Shafi'i, Hanbali) adjusts Hijab (exclusion) rules and special-case resolutions. The 8-step algorithm runs deterministically: pre-distribution validation → Hijab rules → Quranic fixed shares → 'Awl proportional reduction (when shares sum > 1) → Asabat residuary distribution → Radd return (when shares sum < 1) → special cases (Umariyyatan / Gharrawayn, Minbariyyah, Mushtarakah). Output shows fractional and percentage shares per heir, lists every excluded heir with the reason, and explains every algorithmic step. Distinct from the simpler /faraiz-inheritance-calculator which handles only the most common scenarios — use this Warasat tool for cases involving grandparents, son's children, or consanguine/uterine siblings.

The Formula

Quranic shares per Quran 4:11–12 + 4:176 → 'Awl when Σ > 1 → Asabat (residuary classes 1–4) → Radd to non-spouse Quranic heirs when Σ < 1.

Each heir receives a Quranic fixed share if applicable (e.g., husband 1/2 or 1/4, wife 1/4 or 1/8, mother 1/3 or 1/6, daughter 1/2 or 2/3). When the sum exceeds 1, 'Awl reduces all shares proportionally to fit (classic patterns: 6→7, 12→13, 24→27). When the sum is less than 1, the residue passes to Asabat (residuaries) by priority class: descendants → father/grandfather → full siblings → consanguine siblings. If no residuary exists, Radd returns the surplus to non-spouse Quranic heirs in proportion to their fixed shares. Madhhab differences mainly affect Hijab interactions between paternal grandfather and siblings (Hanafi excludes; Maliki/Shafi'i/Hanbali share).

Put It in Perspective

Pakistan's Muslim Family Laws Ordinance (1961) follows classical Hanafi inheritance rules — this calculator's Hanafi mode matches the legal framework used by Pakistani family courts.

Saudi Arabia uses the Hanbali school officially; UAE largely Maliki/Shafi'i; Egypt's 1946 Personal Status Law is largely Hanafi but with Maliki adjustments for orphaned grandchildren.

The 'Awl doctrine was formalized by Ibn Abbas (RA) and later codified by Caliph Umar (RA) — both companions of the Prophet ﷺ.

Shia Ja'fari inheritance can produce dramatically different shares — daughters can exclude paternal uncles, the system of asabat is much reduced. Use a dedicated Shia inheritance tool for those cases.

Practical Examples

1

Husband + Mother + Father (no children): Umariyyatan case — Husband 1/2, Mother 1/6 (1/3 of remaining 1/2), Father 1/3 (residuary).

2

Wife + Mother + Father (no children): Umariyyatan — Wife 1/4, Mother 1/4 (1/3 of remaining 3/4), Father 1/2 (residuary).

3

Husband + 2 Daughters + Mother + Father: 1/4 + 2×1/3 + 1/6 + 1/6 = 27/24 → 'Awl → denom 27. Each share scaled by 24/27.

4

Husband + 2 Full Sisters + Mother (no descendants, no father): 1/2 + 2/3 + 1/6 = 8/6 → 'Awl → denom 8. Husband 3/8, Sisters 4/8 collectively, Mother 1/8.

5

Wife + 1 Daughter + Father (no son): Wife 1/8, Daughter 1/2, Father 1/6 + residue. Σ Quranic = 19/24, Father takes 5/24 residue.

6

Only Mother + 4 Wives + 2 Sisters (Kalalah, no father): Mother 1/6, Wives 1/4 (split equally), Sisters 2/3 → Σ = 13/12 → 'Awl 12→13.

7

Daughter + Son's daughter + Father (no son): Daughter 1/2, Son's daughter 1/6 (completes the 2/3), Father 1/6 + residue 1/6.

Frequently Asked Questions

The simpler Faraiz calculator covers only the most common scenarios — spouse, parents, children, and Kalalah siblings. This Warasat calculator covers EVERY heir category in classical fiqh: grandparents (paternal grandfather, both grandmothers), son's children (when the son has predeceased), and the three sibling types (full / consanguine / uterine), plus full Hijab (exclusion) rules per madhhab, 'Awl proportional reduction, Asabat (residuary) distribution by priority class, and Radd (return). It detects Umariyyatan, Mushtarakah, Akdariyyah, Minbariyyah special cases automatically.
