Islamic Inheritance Law (Faraid): A Comprehensive Overview

What Is Faraid?

Faraid (singular: faridah) is the Islamic law of inheritance — a divinely prescribed system governing the distribution of a deceased person's estate among their heirs. The word comes from the same root as fard (obligation), reflecting that these shares are fixed, binding, and cannot be overridden by the testator's personal wish. The Prophet (PBUH) said: "Learn the faraid and teach it to people, for it is half of knowledge, and it is the first knowledge to be forgotten and the first to be lifted from my ummah" (Ibn Majah, Daraqutni). This statement underscores the centrality of inheritance law to Islamic jurisprudence.

Quranic Foundation

Islamic inheritance law is among the most explicitly detailed subjects in the Quran. Three verses in Surah al-Nisa (4:11–12 and 4:176) set out the specific shares of various heirs with rare precision for a legal text. Allah (SWT) opens the inheritance verses with: "Allah instructs you concerning your children: for the male, what is equal to the share of two females" (4:11), and closes with: "These are the limits [set by] Allah, and whoever obeys Allah and His Messenger will be admitted by Him to gardens beneath which rivers flow, abiding eternally therein; and that is the great attainment" (4:13). The divine framing of inheritance law as hudud (limits set by God) makes altering the fixed shares a grave religious transgression.

Three Conditions for Inheritance

For a person to inherit, three conditions must be met. First, the death of the deceased must be confirmed — either by direct knowledge, legal declaration, or a court ruling of presumed death after a set period. Second, the heir must be alive at the time of the deceased's death. A fetus may inherit if born alive. Third, the relationship entitling to inheritance must be established — through kinship (nasab), marriage, or in early Islamic law, the bond of wala' (manumission). Contemporary inheritance disputes most often involve confirming the existence and degree of kinship.

Impediments to Inheritance

Certain conditions disqualify an otherwise valid heir from inheriting. Killing: a person who intentionally and unjustly kills the deceased cannot inherit from them. The Prophet (PBUH) said: "The killer does not inherit" (Tirmidhi, Nasa'i). Difference of religion: a Muslim does not inherit from a non-Muslim, and a non-Muslim does not inherit from a Muslim, according to the majority position. The Hanafi school applies this strictly; some contemporary scholars have revisited the ruling for certain cases, though the classical position remains authoritative. Slavery (historically) was a third impediment, but this has no modern application. Legitimate uncertainty of timing of death may also affect inheritance.

Categories of Heirs

Islamic inheritance law divides potential heirs into three main categories. First, Ashab al-Furud (fixed-share heirs): those whose shares are explicitly stated in the Quran or established Sunnah. Their shares are calculated first from the estate. Second, Asabat (residuary heirs): male agnatic relatives who inherit what remains after the fixed-share heirs receive their portions. If there are no fixed-share heirs, they take the entire estate. Third, Dhawu al-Arham (uterine relatives): those related through females and not covered by the first two categories. The Hanafi and Hanbali schools allow dhawu al-arham to inherit in the absence of asabat, while the Maliki and Shafi'i schools prefer giving the estate to the public treasury (bait al-mal) in such cases.

The Doctrine of Hajb (Exclusion)

Hajb refers to the exclusion of an heir by a closer relative. A closer heir may exclude a more distant one entirely (hajb al-hirman) or reduce another heir's share (hajb al-nuqsan). For example, a son excludes the brother entirely. A husband's share is reduced from one-half to one-quarter if there are children. These rules are carefully worked out in classical fiqh texts and form a major part of the faraid discipline. Correctly identifying which heirs are present and applying the appropriate hajb rules is the core technical challenge in any inheritance calculation.

The Importance of Islamic Wills

A Muslim may dispose of up to one-third of his estate by bequest (wasiyyah) to non-heirs or charitable causes, but not to heirs. The Prophet (PBUH) said: "It is not permitted for a Muslim who has something to bequeath to sleep two nights without having his will written and kept with him" (Bukhari and Muslim). The two-thirds that cannot be bequeathed is reserved for the fixed-share heirs and residuary heirs according to the Quranic scheme. Writing a valid Islamic will is an obligation upon every Muslim of means, ensuring that the estate is distributed according to divine guidance.
