Sunni Faraid distribution per Qur'an 4:11, 4:12 & 4:176 — with Awl, Radd & ʿAsaba
⚠ Important — please read: This calculator is a study and estimation aid only and must not be relied upon on its own. It calculates the shares of the core heirs and assumes no surviving grandparents (paternal grandfather or grandmothers) and no distant kin such as uncles, nephews, or a daughter's children. The result can be affected by circumstances it does not capture. For any real estate, always confirm the distribution with a qualified, authentic scholar (ʿālim) or an Islamic court — their ruling takes precedence over this tool.

How these shares are derived — the rules in brief
Order of settlement (before any heir inherits)
Funeral expenses → debts → bequest (wasiyyah, capped at one-third) → the remainder (residue) is divided among heirs.
Fixed shares (Furud)
Husband: ½ (no descendant) or ¼ (with descendant). Wife/wives: ¼ or ⅛, shared equally. Mother: ⅙ (with a child or two-plus siblings) or ⅓. Father: ⅙ when a son or son's son exists, otherwise ⅙ plus the residue, or the whole residue if there is no descendant. One daughter: ½; two or more: ⅔ shared. Son's daughters mirror daughters and take ⅙ to complete ⅔ alongside a single daughter.
The 2:1 residuary (ʿAsaba)
When a son is present, sons and daughters take the residue in a 2:1 ratio. The same applies to son's children, and to full or paternal siblings when no nearer residuary exists. The rationale given in Islamic law is the male's financial responsibility for his household, not differing worth.
Maternal siblings
Blocked by any descendant or the father. Otherwise one takes ⅙; two or more share ⅓ equally (no 2:1).
Blocking (Hajb)
A nearer relative excludes a more distant one — e.g. a son blocks grandchildren and all siblings; the father blocks all siblings; a full brother blocks paternal siblings.
Umariyyatayn
With only a spouse and both parents, the mother takes one-third of the remainder after the spouse's share, and the father takes the rest.
ʿAwl (increase)
When the fixed shares add up to more than the whole, every share is reduced proportionally by raising the common denominator.
Radd (return)
When fixed shares total less than the whole and there is no residuary heir, the surplus returns proportionally to the fixed sharers — the spouse does not participate.
Scope & conventions. This tool follows the majority Sunni position and applies these specific choices, on which schools can differ:
it returns surplus to the fixed heirs (radd), excluding any spouse from that return; in the rare case where only a spouse survives with no other heir, it gives the whole estate to that spouse (many contemporary courts do this, though the classical view passes the surplus to the public treasury or distant kin);
in the ʿUmariyyatayn (spouse + both parents) it gives the mother one-third of the remainder; and in the Mushtaraka case it follows the Hanafi/Hanbali view (full brothers take no share).
It does not include grandparents, more distant residuaries (uncles, nephews), distant kin (dhawū al-arḥām), the grandfather-with-siblings cases, or Shia (Jaʿfari) rules.
Real estates can involve details a calculator cannot capture. For an actual estate, confirm the distribution with a qualified scholar or Islamic court before acting.
