Formula
Each heir receives their Quranic share (1/2, 1/4, 1/8, 2/3, 1/3, 1/6), with residual going to Asabah heirs
Islamic inheritance follows a priority-based system. First, fixed-share heirs (ashab al-furud) receive their Quranic portions. Then, residual heirs (asabah) — primarily sons, then father — receive the remainder. If shares exceed the estate, proportional reduction (Awl) is applied. Sons receive twice the share of daughters when inheriting together as residual heirs.
Worked Examples
Example 1: Deceased Male with Wife, Son, and Daughter
Problem:A man passes away leaving an estate of $100,000. His heirs are his wife, 1 son, and 1 daughter. Calculate each heir's share.
Solution:Wife's share = 1/8 (has children) = $12,500\nRemainder = $100,000 - $12,500 = $87,500\nSon gets 2 parts, daughter gets 1 part = 3 total parts\nSon = $87,500 × 2/3 = $58,333.33\nDaughter = $87,500 × 1/3 = $29,166.67
Result:Wife: $12,500 | Son: $58,333 | Daughter: $29,167
Example 2: Deceased Female with Husband, Mother, and Father
Problem:A woman passes away with $200,000. Her heirs are her husband, mother, and father. No children.
Solution:Husband's share = 1/2 (no children) = $100,000\nMother's share = 1/3 (no children, no multiple siblings) = $66,666.67\nFather's share = Residual = $200,000 - $100,000 - $66,666.67 = $33,333.33
Result:Husband: $100,000 | Mother: $66,667 | Father: $33,333
Frequently Asked Questions
What is the Islamic inheritance system (Faraid)?
Faraid is the Islamic law of inheritance derived primarily from the Quran (Surah An-Nisa, verses 11-12 and 176) and the Sunnah of Prophet Muhammad (peace be upon him). It prescribes specific shares for designated heirs based on their relationship to the deceased. The system is mandatory and cannot be altered by a will for the designated heirs, though up to one-third of the estate can be bequeathed to non-heirs through a wasiyyah (bequest). Faraid aims to distribute wealth across the family rather than concentrating it, ensuring that close relatives — including women — receive their rightful shares. The system considers the closeness of relationship, the generation of the heir, and financial responsibilities.
