Specify surviving spouse, children, and parents (Surah An-Nisa 4:11–12)

Key Principles of Islamic Inheritance (Ilm al-Fara'id)

1. The 1/3 Wasiyyah CapWhen Sa'd ibn Abi Waqqas (RA) asked to bequeath two-thirds of his wealth, the Prophet ﷺ replied: “One-third, and one-third is much.” (Sahih al-Bukhari 2742). Bequests within 1/3 go to charities or non-heirs.
2. 'Awl (Proportional Reduction)When fixed Quranic fractions exceed 100% (e.g. a Husband 1/2 + Two Daughters 2/3 + Both Parents 1/3 = 15/12), all shares are proportionally scaled down so every heir receives their fair ratio.
3. Radd (Proportional Return)When fixed fractions total less than 100% and there is no residuary male agnate ('Asabah), the remaining surplus is returned proportionally to the eligible blood Quranic heirs.

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

  1. Tajheez wa Takfeen: Necessary funeral and burial preparation expenses without extravagance.
  2. Qada' ad-Duyun: Settlement of all debts owed to people and Allah (unpaid Zakat, expiations/Kaffarat).
  3. Tanfeez al-Wasaya: Execution of voluntary bequests up to maximum 1/3 to non-heirs.
  4. 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.
