Book of Inheritance Shares (Farā'id)
Primary text
If two sons inherit, one dies leaving a daughter, and the remaining son admits the existence of his father's mother, the basis for denial is four shares, of which the admitting party has three-fourths. The basis for admission is seventy-two shares, of which the admitting party has forty shares. The surplus in his possession is fourteen shares, which he pays to the woman acknowledged. This ultimately reduces to thirty-six shares: the admitting party has twenty, the daughter has nine, and the acknowledged mother has seven.

The method of Abu Hanifa is applied similarly, except the shares of the mother (seventeen) are added to the shares of the admitting heir (forty), totaling fifty-seven, and these divide three-fourths of the estate. What accrues to each is determined by this division. If the daughter admits the mother, she has fifteen shares from the basis of admission, and one-fourth (eighteen shares) is in her possession. The surplus in her possession is three shares, which she pays to the acknowledged party. If the son admits his father's wife, who is the mother of the second deceased, the basis for admission is ninety-six shares, of which he has fifty-six, and three-fourths are in his possession. The surplus is sixteen shares, which he pays to the acknowledged party, leaving him with fifty-six, the acknowledged wife with sixteen, and the daughter with twenty-four. This reduces to twelve shares: the admitting heir has seven, the acknowledged wife has two, and the daughter has three.
