Inheritance Calculator

The Shariawiz Islamic Inheritance Calculator software helps you identify your Islamic heirs and their shares. Raqaba has tested and certified that the Shariawiz Islamic Inheritance Calculator is accurate and complies with the Sharī‘a rules of inheritance.

For the past 14 centuries, any Muslim scholar who was tasked with distributing an estate would first identify the Islamic heirs by applying the blocking rules (hajb) in order to determine the number of shares in the estate. The Shariawiz Calculator follows the same time-honored process; it will identify the Islamic heirs by applying the blocking rules to your answers to determine the number of shares in the estate and then assign the shares to each Islamic heir. The Shariawiz Calculator programmed the blocking rules (hajb) on the front end of the calculator so you do not have to list every possible Islamic heir. For example, if you have a son, the questions will stop. There is no need to ask about any other family members, like siblings, because a son blocks them.

Answer a few questions about your family tree, and the calculator will automatically determine your legal heirs and their shares.

Important note: An Islamic heir is a beneficiary who inherits automatically as part of the fixed-share distribution system. According to Sharī‘a, non-Muslim relatives are not automatic Islamic heirs; therefore, they are only entitled to inherit through a bequest. For example, a non-Muslim wife or non-Muslim child is not an eligible Islamic heir, but you are entitled to leave her a bequest of up to one-third of your estate. Sharī‘a limits bequests to an aggregate total of 1/3 for all bequest beneficiaries and prohibits leaving a bequest to an Islamic heir. For example, a bequest is not valid if it gives an Islamic heir—like a daughter, son, or father—more than his or her prescribed share. This is based on the famous Hadith that the Prophet (PBUH) said: “There shall be no bequest to an Islamic heir.”

Please do not include any non-Muslim relatives in the family tree because they are not Islamic heirs. If you do, then the distribution of your estate would not be consistent with Sharī‘a. For an accurate Islamic inheritance calculation, include only Muslim relatives and children born of an Islamic marriage in the family tree. A child who is born outside of marriage is only considered an Islamic heir from the maternal side. In other words, a child outside of marriage does not inherit from his or her father; he or she only inherits from the mother’s side. However, the father of a child outside of marriage is free to leave the child with a bequest.

What maḏhab (School of Law) do you follow?

Maḏāhib (maḏhab singular) are Sharīʿa doctrinal schools. In the 7th century, Muslim juristic knowledge started as study circles (halaqas) in which a pious Muslim scholar - surrounded by people - would debate religious issues and teach interested students. The knowledge and production of legal doctrine began in these circles that gave birth to the Maḏāhib (Sharīʿa doctrinal schools). There are four schools in Sunni law: Ḥanafī, Shāfi’ī, Mālikī, and Ḥanbalī. Al-Jumhūr/Majority mean that three or more of the schools have the same fiqh ruling on an inheritance issue. If you do not follow a specific maḏhab, most people would select the majority school (al- Jumhūr)

What is your gender?

If you are married, is your spouse alive?

Only a legal marriage results in entitlement to inheritance. A legal marriage is one recognized by the state of your residence. Generally, the United States recognizes an Islamic marriage contracted abroad if the marriage complied with the law of the country it was contracted in.
Reminder: Non-Muslim relatives are not Islamic heirs. If your father is alive, but is not Muslim, answer "No" to this question.

Is your father alive?

A non-Muslim father, or stepfather (whether Muslim or non-Muslim) or father of an illegitimate child are not Islamic heirs; therefore, they are not eligible to inherit automatically in the Islamic fixed share default system. The Sharia, however, grants you the right to leave them, if you wish, a discretionary bequest in your will as long as it does not exceed one-third of your estate.

Is your grandfather (your father's father) alive?

Paternal grandfathers are eligible to inherit, while maternal grandfathers are not.

Is your mother alive?

If your mother was not married to your father when you were born, according to Islamic law, you are entitled to inherit only from her and she is entitled to inherit from you. In other words, you inherit through the maternal line, not paternal line. A stepmother is not eligible to inherit, but you are free to leave her a specific bequest in your will as long as it does not exceed one-third of your estate.

However, the father of a child outside of marriage is free to leave the child with a bequest.

Your answers indicate that you do not have any other surviving paternal Islamic heirs. The next and final eligible Islamic heir category is dhawūʾl l-arḥām. With no surviving Qur’anic heirs or taʿsīb heirs (residuary heirs), the Ḥanbalī, Ḥanafī, and Shāfi’ī maḏāhib (schools) will distribute the estate to dhawūʾl l-arḥām. The Mālikī madhab (school), on the other hand, will distribute the estate to the public treasury. Modern Mālikī scholars, however, have concluded that in the absence of a true Islamic government, such as in the United States, the estate will be distributed to dhawūʾl l-arḥām.

There is no exact English translation for dhawūʾl l-arḥām. The most common translations are “distant kindred,” “uterine heirs” or “outer family.” Al-rḥām (plural: Al-ʾarḥām) means “to have mercy, compassion or sympathy.” In the Qur’an, it means “a familial relationship.” (Qur’an 4:1. Fear God in Whose name you make requests one of another, and sever not the ties of kinship [Al-ʾarḥām]. God watches well over you.). Juristically, dhawūʾl l-arḥām refers to relatives that are not Qur’anic heirs or taʿsīb heirs (residuary heirs). While spouses are Qur’anic heirs, they are not eligible to receive radd if there are other surviving Islamic heirs.

Muslim scholars divided a dhawūʾl l-arḥām–specific relative into one of three categories:

1. Descendants of daughters:
Children of your daughters and their children;
and Children of your son’s daughters and their children.

2. Descendants of your father: Children of sisters (both full or paternal) and their children Daughters of brothers (both full or paternal) and their children
Children of maternal brothers and their children
Daughters of male nephews (full and paternal) and their children
Maternal uncles – the decedent’s father’s brother from his mother, decedent father’s uncle, decedent’s grandfather’s uncle from his mother, and their children;
Aunt (full, paternal, or maternal), including decedent’s father’s aunts or grandfather’s aunts and their children;
Daughters of uncles (full, paternal, or maternal) and their children;
Daughters of the sons of uncles (full, paternal, or maternal) and their children;
Father’s mother’s father;
Mother’s father’s father’s father;
Father’s mother’s mother’s father’s father;
Farther’s mother’s father’s father’s father;
Father’s mother’s mother’s father;
Father’s mother’s father’s father’s mother’s father;
Farther’s mother’s father’s father;
Mother’s mother’s father’s father’s father;
Mother father’s father’s father’s father;
Aunt’s aunt (sharing father or sharing mother);
Father’s uncle (sharing mother); and
Grandfather’s uncle (sharing mother).

Descendants of your mother: Mother’s siblings and their children (full, paternal, or maternal);
Mother’s mother’s siblings and their children (full, paternal, or maternal);
Father’s mother’s siblings and their children;
Father’s aunts and uncles and their children;
Mother’s aunts and uncles and their children;
Mother’s father’s father’s father;
Mother’s father’s fathers’ mother;
Father father’s mother’s mother;
Father’s father’s mother’s mother’s mother;
