The science of inheritance
Islamic inheritance (faraid) is a precise system laid out in the Quran. The main shares are given in Surah an-Nisa 4:11-12, after which Allah says: 'These are the limits set by Allah' (an-Nisa 4:13). Distributing an estate by these shares is an obligation and an act of justice.
How it works
After the deceased's debts are paid and any valid bequest (up to one-third, not to an heir) is carried out, the remainder is divided. Some heirs receive fixed shares (fard) such as a half, a quarter, or a sixth; the residue passes to the residuary heirs (asaba). Some heirs block others. If the fixed shares exceed the estate they are reduced proportionally (awl); if a surplus remains with no residuary it returns to the fixed-share heirs (radd).
A guide, not a fatwa
This calculator handles the common cases - spouse, children, parents, grandmothers, and full or maternal siblings - using rules agreed across the Sunni schools. It does not handle every situation (for example a grandfather inheriting alongside siblings, paternal half-siblings, or grandchildren), and the schools differ on some cases. Always have the final distribution confirmed by a qualified scholar or an Islamic inheritance authority before acting on it.
Common questions
How accurate is this?
+
It computes the exact Quranic shares for the common heirs using agreed rules and exact fractions. But faraid has many cases this tool does not cover, and the schools differ on some - treat the result as a guide and confirm it with a scholar.
What about debts and bequests?
+
They come first: pay the deceased's debts, then carry out any valid bequest (wasiyyah, up to one-third, not to an heir), and only then divide the remainder by these shares.
Why do men sometimes receive more than women?
+
In some cases a male heir receives twice a female of the same degree, because Islamic law places financial duties on the man (the dowry, and maintaining his wife and family) that the woman does not bear. In other cases women inherit equally or more; it is a balance of rights and duties.
Is anything saved?
