The Importance of Islamic Wills

The distribution of a deceased Muslim's estate is not left to personal whim; it is strictly mathematically detailed by Allah in Surah An-Nisa of the Holy Quran. Ensuring your wealth is distributed according to Shariah is a major religious obligation.

First Steps Before Distribution

Before any wealth is divided among the heirs, three things must be deducted from the total estate:
1. Funeral Expenses: The cost of the Janazah and burial.
2. Debts: All outstanding debts (both to people and to Allah, such as unpaid Zakat) must be paid.
3. The Bequest (Wasiyyah): The deceased can will up to a maximum of one-third (1/3) of their estate to charity or to non-heirs.

The Primary Heirs

After deductions, the remainder is distributed to the primary heirs. There are five categories of primary heirs who, if alive, will almost always inherit: the husband/wife, the son, the daughter, the father, and the mother. The exact fractions (e.g., 1/2, 1/4, 1/8) depend on the specific combination of surviving relatives.
