Ashabah, Furudh, 'Aul, and Radd: Islamic Inheritance Terms Explained Simply

Four key terms in the science of faraid

When reading explanations of Islamic inheritance, we often encounter the terms furudh, ashabah, 'aul, and radd. For many families, these terms sound technical and make the division feel complicated. In fact, the idea is quite simple: some heirs already have fixed shares, some receive the residue, and then sometimes that residue is not enough or is instead in excess.

This article explains all four in everyday language. It is general information, not a fatwa, and does not replace the advice of those who are experts in the field.

Furudh: shares that have been determined

Furudh are shares whose amounts have been determined in the Qur'an, namely An-Nisa 4:11, 4:12, and 4:176, and adopted in KHI Book II. Heirs who receive them are called dzawil furudh. Their amounts often differ depending on whether or not there is a child.

• Husband: 1/2 if there is no child, 1/4 if there is a child.
• Wife: 1/4 if there is no child, 1/8 if there is a child, and that share is divided jointly if there is more than one wife.
• Daughter: 1/2 if single, 2/3 if two or more; if together with a son the ratio 2:1 applies.
• Father: 1/6 if there is a child.
• Mother: 1/6 if there is a child or two or more siblings; if neither exists, 1/3.

The characteristic of furudh is that it is fixed: as long as its conditions are met, that share does not change because other heirs receive more or less, except in the situations of 'aul and radd discussed below.

Ashabah: receivers of the residue

Ashabah are heirs who receive the residue of the estate after the dzawil furudh take their shares. There are two forms most often encountered in practice in Indonesia.

• Ashabah binafsihi — receives the residue by virtue of himself, generally male heirs such as a son, a son's son, the father (when there is no child), the grandfather, and brothers.
• Ashabah bilghairi — becomes a receiver of the residue because of being together with a male heir of equal degree, namely a daughter who is together with a son, with a 2:1 division.

It should be remembered that, according to Supreme Court jurisprudence, full siblings are blocked by the existence of a child or by the father. So the presence of just one child is enough to close the right of siblings.

'Aul: when the total of shares exceeds one

Sometimes, after all the furudh shares are added up, the result is more than one whole. This is 'aul. The solution is not to cut the share of one of the heirs, but to raise the denominator, so that all shares shrink proportionally.

Example: Bu Aminah passed away leaving a husband, mother, father, and two daughters.

The initial total is 3 + 2 + 2 + 8 = 15 out of 12. Therefore the denominator is raised to 15, and the total becomes exact: 3/15 + 2/15 + 2/15 + 8/15 = 15/15.

Radd: when there is still a residue

The opposite of 'aul, radd occurs when the total of the furudh shares is less than one, while there is no ashabah receiving the residue. That residue is returned to the dzawil furudh heirs other than the husband or wife, in proportion to their shares.

Example: Bu Salma passed away leaving a mother and one daughter, without a husband.

1. Initial shares: daughter 1/2 (6/12) and mother 1/6 (2/12). The total is 8/12, with a residue of 4/12.
2. The ratio of their shares is 3:1, so the residue is divided in that ratio: daughter 3/12 and mother 1/12.
3. Final result: daughter 6/12 + 3/12 = 9/12 (3/4) and mother 2/12 + 1/12 = 3/12 (1/4). The total is exactly 1.

The husband or wife does not receive radd because their share is already fixed and does not increase. It should be noted that KHI does not regulate 'aul and radd in detail.

The scholars differ in opinion about radd: some return the residue to specific heirs, some hand it over to the baitul mal or more distant relatives. Therefore, for real cases it is best to consult the Religious Court (Pengadilan Agama) or an ustadz you trust.

Practical steps for your family

1. List all living heirs, complete with their gender and their relationship to the deceased.
2. Mark who receives furudh and who becomes ashabah.
3. Add up the furudh shares. If more than one, prepare an 'aul adjustment; if less than one and there is no ashabah, study the possibility of radd.
4. Make sure matters of debt, funeral costs, and wasiat are settled first before the estate is divided.
5. If there are differences of interpretation within the family, ask the Religious Court (Pengadilan Agama), a notary/PPAT for land matters, or an ustadz you trust.

Calculating 'aul and radd manually is indeed easy to get wrong, especially when there are many heirs. IndoWaris can help draw the family tree and calculate each person's share transparently, so the result can be checked together before a final decision is made.
