A table of classic fixed shares (furud) for husband, wife, parents, daughters, sisters, and maternal siblings.

Each ruling below links to the Quran, a Hadith, or IslamQA. Links open on those sites.

Classic fixed shares

The Quran names shares of one-half, one-quarter, one-eighth, two-thirds, one-third, and one-sixth. The exact fraction depends on who else survives. This table is a study aid, not a ruling.Sources:Quran 4:11 (Shares of children and parents, after debts and bequests; opens in a new tab)Quran 4:12 (Shares of spouses and maternal siblings, after debts and bequests; opens in a new tab)IslamQA 225165 (Rules of inheritance: fixed shares, residue, and impediments; opens in a new tab)

Residue after fixed shares

After Quranic heirs take their fractions, the residue goes to agnates. A son takes twice a daughter's share of that residue. If no son survives, a daughter often takes a fixed share instead.Sources:Sahih al-Bukhari 6732 (Give the fixed shares; the remainder goes to the closest male relative; opens in a new tab)Sahih Muslim 1615a (Give the shares to those entitled; the remainder goes to the nearest male heir; opens in a new tab)Quran 4:11 (Shares of children and parents, after debts and bequests; opens in a new tab)IslamQA 12911 (A daughter's share: one-half, two-thirds, or residue with a son; opens in a new tab)

If the fractions add up to more or less than the whole estate, the method changes. Read 'awl and radd.Sources:IslamQA 131556 (Awl reduces every Quranic share in proportion; opens in a new tab)IslamQA 160948 (Radd versus the public treasury by school; opens in a new tab)
