Distribution
Note: This handles the common heirs (spouse, sons, daughters, parents) and the rule that a son receives double a daughter. Cases with siblings or grandparents need a qualified scholar.

How Islamic Inheritance Works

Islamic inheritance law is one of the most precise systems in the Shariah, derived mainly from Surah An-Nisa (4:11-12). Before distribution, the estate is settled in this order:

  • Pay funeral expenses.
  • Clear all debts of the deceased.
  • Honour any bequest (Wasiyyah) up to a maximum of 1/3 (not to existing heirs).
  • Divide the remainder among the legal heirs by fixed shares.

Fixed Shares Of Common Heirs

HeirWith childrenWithout children
Husband1/41/2
Wife1/81/4
Mother1/61/3 (most cases)
Father1/6 + residueresidue
Sons & daughtersTake the remaining estate; each son = 2 × each daughter

The 2:1 Principle

Why a son receives more

The male heir carries the financial responsibility for his wife, children and family, while a woman's wealth is entirely her own. The larger share reflects greater obligation, not greater value.

Worked Example

Estate Rs 10,000,000. Heirs: wife, 2 sons, 1 daughter.

  • Wife (with children) = 1/8 = Rs 1,250,000
  • Remaining Rs 8,750,000 split as 2+2+1 = 5 parts.
  • Each son = Rs 3,500,000; daughter = Rs 1,750,000
