Islamic Inheritance Calculator (Mirath)
Estimate how an estate is divided among common heirs under Islamic inheritance rules. This covers frequent cases — see the important note below.
How Islamic inheritance works (briefly)
After funeral costs, debts and any valid bequest (up to one-third), the remaining estate is divided among heirs in fixed shares set out in the Quran (Surah An-Nisa 4:11–12). A surviving spouse, parents and children receive prescribed portions, and among children a son generally receives twice the share of a daughter. The full science of Faraid includes residuaries, blocking rules and many specific situations, which is why scholarly guidance is essential for an exact division.
