The Inheritance (Mirath) Calculator distributes an estate among heirs according to the Quranic shares defined by Islamic inheritance law (Faraid) — a fixed, rule-based system where shares for spouses, children, parents and other relatives are set by scripture rather than left to a will, except for the discretionary one-third that can be willed elsewhere.
Islamic inheritance law assigns specific fractional shares (like a son typically receiving double a daughter's share, or a widow receiving one-eighth if there are children) based on the exact combination of surviving heirs, which is why the calculation changes significantly depending on who is alive at the time of death — this tool asks for your specific family situation to apply the correct Quranic shares.
Can a Muslim will away their entire estate as they choose?
No — under Islamic law, a person can will at most one-third of their estate freely (and generally not to an heir who already has a fixed Quranic share); the remaining two-thirds must be distributed according to the fixed Faraid shares among legal heirs.
Why does a son typically inherit double what a daughter inherits?
The Quranic principle (Surah An-Nisa 4:11) generally assigns male heirs double the share of equivalent female heirs, reasoned historically by the differing financial obligations placed on men (like mahr and full family maintenance) versus women under Islamic law.
Does this calculator account for different schools of Islamic jurisprudence?
This tool applies the widely-followed Quranic share rules common across major schools of thought for standard cases; edge cases and rare heir combinations can have differing scholarly opinions, so consult a qualified Islamic scholar for legally binding estate division.
