Key Principles of Islamic Inheritance (Ilm al-Fara'id)
Calculated Heir Distribution
The Prophetic Imperative of Preparing a Will
Writing an Islamic will ensures that debts are paid, funeral expenses are settled according to the Sunnah, and your estate is distributed strictly in accordance with Allah's divine boundaries:
“It is not permissible for any Muslim who has something to bequeath to stay for two nights without having his will written with him.” — Sahih al-Bukhari (2738)
The Four Successive Rights Over an Estate
- Tajheez wa Takfeen: Necessary funeral and burial preparation expenses without extravagance.
- Qada' ad-Duyun: Settlement of all debts owed to people and Allah (unpaid Zakat, expiations/Kaffarat).
- Tanfeez al-Wasaya: Execution of voluntary bequests up to maximum 1/3 to non-heirs.
- Taqseem al-Mawarith: Distribution of remaining estate to Quranic heirs according to Surah An-Nisa (4:11-12, 176).
Fiqh Corrections Implemented
Unlike simplistic calculators that cause negative residuary amounts, our Fara'id engine adheres to classical Sunni jurisprudence:
- • Hajb (Blocking): Closer relatives block more distant relatives (e.g. Son blocks brothers and nephews).
- • 'Awl: When prescribed shares exceed 1, denominators are proportionately adjusted.
- • Radd: When surplus remains with no Asabah, surplus is redistributed to non-spousal Quranic sharers.
