Quranic sharers (Zawil Furud)

Key rules

1. Husband: 1/4 with children, 1/2 without.
2. Wife: 1/8 with children, 1/4 without (shared equally among wives).
3. Daughter: 1/2 if one, 2/3 if two or more; with sons, residuary in 2:1.
4. Father: 1/6 with a son; 1/6 plus residue with daughters only; residuary if no children.
5. Mother: 1/6 with children or 2+ siblings, otherwise 1/3.

Residuaries (Asabah)

Class 1: descendants · Class 2: father/grandfather · Class 3: siblings and their sons · Class 4: uncles and cousins. An earlier class excludes later ones.

Awl & Radd

Awl: if shares exceed 1, all are reduced proportionally. Radd: if less than 1 and no residuary, shares (except spouse) are increased proportionally.
