Legal Basis of Islamic Inheritance in Indonesia: An-Nisa 4:11, 4:12, 4:176 and KHI

Why the Legal Basis Needs to Be Known

When a father or mother passes away, the question that most often arises in the family is: who is entitled, and how much is their share? The answer to that question is not born from custom or the agreement of the children alone, but from rules that have already been established. In Indonesia, there are two main references that go hand in hand: the verses of the Qur'an and Book II of the Compilation of Islamic Law (KHI).

Understanding both helps the family discuss calmly, because what is being discussed is no longer a matter of who is more loved, but a matter of rules that are already clear.

The Qur'an: Three Verses That Form the Foundation

The distribution of inheritance in Islam rests primarily on three verses in surah An-Nisa. All three are often cited directly during family deliberations or in the Religious Court room.

An-Nisa 4:11

Summary of its meaning: Allah decrees that the share of a son is twice the share of a daughter; a single daughter receives one-half; two or more daughters receive two-thirds; the father and mother each receive one-sixth if there is a child; if there is no child and no two or more siblings, the mother receives one-third.

This verse is the most important basis for the relationship between parents and children. From here we know the 2:1 pattern between sons and daughters, as well as the shares of the father and mother.

An-Nisa 4:12

This verse regulates the shares of husband and wife. The husband receives one-half if there is no child, and one-quarter if there is a child. The wife receives one-quarter if there is no child, and one-eighth if there is a child. If a husband leaves more than one wife, that one-quarter or one-eighth share is divided jointly among the wives.

An-Nisa 4:176

This verse speaks about the inheritance of siblings in the state of kalalah, that is, when someone passes away without leaving a child and without a father. From here we know that full siblings do have a share, but only under certain conditions.

Book II of the Compilation of Islamic Law

KHI is a collection of rules that serves as a guideline for Muslims in Indonesia and is widely used by the Religious Courts. Book II of KHI contains Articles 171 to 214, which regulate everything from the definition of heirs to wills and grants. Several important points from there:

• Article 171 provides definitions: who is called the testator, heir, inheritance property, and will. Here it is also emphasized that an heir is a person who is Muslim. Being Muslim is a requirement to become an heir, not one of the impediments in Article 173.
• Article 173 mentions the impediments to inheritance in a limited way: an heir who is found guilty of killing, attempting to kill, or seriously maltreating the testator, or because of slandering the testator with a criminal accusation punishable by five years or more.
• Article 185 regulates substitute heirs: a grandchild whose parent passed away earlier takes the share that their parent should have received, and that share is divided among the children of that parent with the 2:1 pattern between males and females.
• There is also a maximum limit of one-third for wills, as well as rules about grants by parents to children, which are found in the articles at the end of Book II.

In other words, KHI does not replace the Qur'an, but rather summarizes and details its implementation so that it can be applied in Indonesia.

A Brief Example: These Rules in Numbers

Mr. Hasan passed away leaving a wife, mother, one son, and one daughter. After debts, funeral expenses, and wills (if any) are settled, the net estate ready for distribution amounts to Rp 720,000,000. Note how the numbers work:

These numbers fully follow the pattern mentioned in An-Nisa 4:11 and 4:12. Since there are no siblings, the discussion of An-Nisa 4:176 does not appear here.

Matters That Require Caution

Not all problems are solved by just three verses and one book. Some situations require further study:

1. The gharrawain case, when the heirs consist only of a husband or wife, the mother, and the father, the method of calculating the mother's share has its own discussion among scholars.
2. Grandfather, grandmother, and distant relatives (dzawil arham) have more complicated calculations and are not always in the same discussion in every reference.
3. Wills and grants touch on limits that can affect the inheritance property, so they should be examined before distribution is carried out.
4. If one of the heirs passes away before the property is divided, chain inheritance applies, the settlement of which follows its own rules.

Therefore, for situations that are not simple, the safest step is to consult with the Religious Court, a notary or PPAT, or an ustadz whom you trust.

Practical Next Steps

Start by recording who among the family members is still alive and their relationship to the deceased. After that, arrange the order: clear the property of debts, funeral expenses, and wills, then calculate the shares of the heirs. Keep all documents such as death certificates, family cards, and proof of asset ownership in one place so they are easy to show when needed.
