Full Siblings in Islamic Inheritance: When They Receive a Share, When They Are Excluded

Full siblings: heirs who often wait at the back of the line

In the list of heirs according to the Compilation of Islamic Law (KHI) Book II, full siblings are among the heirs. In practice, however, many families are surprised to learn that full siblings often receive no share at all. Not because they are forgotten, but because Islamic inheritance law recognizes an order of priority: closer heirs block or exclude (hijab) more distant ones.

This article discusses when full siblings actually receive inheritance, when they are excluded, and how their share is calculated. It is general information, not a fatwa or legal advice.

The legal basis: An-Nisa 4:11, 4:12, and 4:176

The Qur'an regulates inheritance in detail. An-Nisa 4:11 and 4:12 mention the main shares (furudh) for children, parents, husband, and wife, and touch on the case of a deceased who leaves neither children nor parents. An-Nisa 4:176 specifically speaks about inheritance in the state of kalalah, that is, when the deceased leaves no child.

Summary of the meaning of An-Nisa 4:176: if a person dies without children and has one sister, that sister receives one-half; if two sisters or more, they receive two-thirds; and if the heirs consist of brothers and sisters, the male's share is twice the female's share.

KHI Book II (Articles 171-214) is the practical reference in Indonesia and is basically in line with that framework. Because this verse was revealed in the context of a deceased who had no children, the scholars concluded that the presence of a child shifts the position of siblings.

When full siblings receive inheritance

Full siblings have the opportunity to receive inheritance mainly when:

• The deceased leaves no child or descendant. This is the most decisive condition. The presence of a child means siblings do not inherit.
• The deceased's father has passed away. As long as the father is alive, the father inherits and the siblings receive no share.
• There is still remaining property after the specified shares are paid. After the husband, wife, or mother receives their share, the remainder is given to the siblings as ashabah, that is, residuary heirs.
• If there are only sisters: one sister receives 1/2, two sisters or more receive 2/3.
• If there are brothers and sisters: the division is 2:1, the male twice the female.

It should be noted that KHI and fiqh also distinguish full siblings, paternal half-siblings, and maternal half-siblings, with provisions that are not identical to one another. Because the details depend on each family's composition, concrete cases should be consulted with experts, for example the Religious Court or a ustadz you trust.

When full siblings are excluded (hijab)

Hijab means blocked: a person is actually an heir, but receives no share because there is another, closer heir. In the practice of religious courts in Indonesia, siblings are excluded by:

• Children, whether male or female. If the deceased has a child, siblings do not inherit. Some classical fiqh books have different details regarding daughters, so scholars' opinions may differ and should be confirmed.
• The father. As long as the father is alive, siblings do not inherit.

Interestingly, excluded siblings can still affect the mother's share: the presence of two or more siblings makes the mother's share 1/6 instead of 1/3, even though those siblings receive no inheritance. In addition, KHI emphasizes that heirs must be Muslim (Article 171 letters b and c), and Article 173 regulates barriers in the form of certain acts, such as killing, attempting to kill, or severely mistreating the deceased.

Calculation example: wife, mother, two brothers, one sister

Pak Rahmat passed away. After the joint property was separated and debts paid, his net estate was Rp240,000,000. He had no children, and his father had passed away. His heirs: wife, mother, two full brothers, and one full sister.

How to calculate: the wife's Rp60,000,000 plus the mother's Rp40,000,000 equals Rp100,000,000. The remainder of Rp140,000,000 is divided in a 2:1 ratio. The total number of shares is 2 + 2 + 1 = 5, so one share is worth Rp28,000,000. Each brother receives Rp56,000,000 and the sister receives Rp28,000,000. The total is exactly Rp240,000,000, no less and no more.

Compare with another scenario: if Pak Rahmat had left a son, then his siblings would not inherit at all. The mother's share remains 1/6 because there is a child, the wife's becomes 1/8 because there is a child, and the remainder belongs to the son.

Practical checklist before dividing

1. Make sure of the order of death of the heirs. If an heir died before or after the deceased, the result may differ.
2. Separate joint property (gono-gini) and settle debts before calculating the inheritance.
3. Make a complete list: children, father, mother, husband or wife, then siblings. Mark who is still alive.
4. Check the requirements for heirs: Muslim and not subject to the barriers in Article 173 of KHI.
5. Determine who is excluded before calculating, so that no share is counted twice.
6. Only after that calculate the shares. You can use IndoWaris to draw the family tree and calculate shares automatically.

Next steps

If in your family there are full siblings wondering why they receive no share, start by mapping who among the heirs was still alive at the time of the deceased's death. Often the answer is simple: there is a child or father who excludes them. Conversely, if the deceased indeed left no child and no father, do not forget to involve the siblings in the division, because ignoring their rights can lead to disputes later on.

For complicated cases, for example where there are paternal and maternal half-siblings, substitute heirs, or property not yet separated from joint property, it is best to consult the Religious Court, a notary or PPAT, or a ustadz you trust. The final decision remains in the hands of the family, with the intention of dividing fairly and in accordance with sharia.
