Distribute an estate according to the prescribed shares of Surah An-Nisa (4:11-12). Select the surviving heirs, enter the estate value, and we apply the fixed shares (fard) and residue (ta'sib) automatically.
After settling funeral expenses, debts, and bequests up to one-third.
Step-by-step application of the fixed shares (fard) followed by residue distribution.
Based on Quranic shares and the doctrine of 'asabah (agnatic residuaries).
Faraidh (Arabic: الفرائض) — the science of Islamic inheritance — is one of the most precisely codified areas of Islamic law. The Prophet Muhammad ﷺ said: "Learn the laws of inheritance and teach them to the people, for they are half of useful knowledge." (Sunan Ibn Majah). Unlike most fields of fiqh, the core shares are fixed directly in the Quran — primarily in verses 11, 12, and 176 of Surah An-Nisa.
Before any heir receives anything, four prior claims must be settled from the estate, in strict order:
The Quran specifies six fixed fractions: 1/2, 1/4, 1/8, 2/3, 1/3, and 1/6. Spouses, parents, and daughters (in the absence of sons) receive their share as a fixed fraction. The presence or absence of other heirs can shift these fractions (for example, a wife's share is 1/4 with no children but 1/8 with children).
After the fixed shares are distributed, the residue (baqi) goes to the asabah: the male agnatic relatives, in order of closeness — sons, then sons' sons, then father, then paternal grandfather, then full brothers, then paternal half-brothers, and onward. When a son is present, daughters become his "co-residuary" (ta'sib bi-l-ghayr), each receiving half a son's share.
Three corrective doctrines may apply: Aul (proportional reduction) when the sum of fard shares exceeds the whole; Radd (proportional return) when shares fall short and no residuary heir exists; and Hajb (exclusion) when a nearer heir blocks a more distant one (e.g. a son blocks the brothers entirely). Complex cases involving these doctrines should always be reviewed by a qualified scholar.
No. A Muslim cannot bequeath to anyone who is already entitled to a fixed Quranic share. Bequests are reserved for non-heirs, and capped at one-third of the estate after debts. The remaining two-thirds must be distributed according to the Quranic shares.
In Islamic law the son carries the financial obligation to support his wife, his children, his parents in old age, and unmarried sisters. The daughter is herself supported by her father or husband and her wealth remains entirely her own. The 2:1 ratio reflects this asymmetric duty — daughters keep their share for themselves; sons must spend theirs to maintain a family.
No. This calculator is educational and covers common cases. Real estates frequently involve doctrines of Aul, Radd, Hajb, and the special rules for half-siblings and grandchildren that require scholarly judgement. Always have your final distribution reviewed by a qualified 'alim or by an Islamic court (mahkama shar'iyya) in your jurisdiction.
If no Quranic heir or asabah exists, the estate typically reverts to the public treasury (bayt al-mal) for the benefit of Muslims at large. Some scholars allow radd to distant relatives (dhawu al-arham) such as maternal uncles and paternal aunts before this step.
