If a person dies leaving a full sister and a paternal uncle, she receives one-half.

If a person dies leaving two full sisters, neither receives one-half, because she is not alone.

If a person dies leaving a full sister and a full brother, she is not entitled to one-half, because the condition is that she be alone. Here we add two conditions: that there be no inheriting descendant and no inheriting male ascendant. Thus, a full sister must be alone, with no inheriting descendant and no inheriting male ascendant present. The inheriting descendants are the son, daughter, son’s son, son’s daughter, and the like; and the male ascendants are the father, grandfather, and the like.

If a person dies leaving a full sister and a father, she does not receive one-half, because of the presence of an inheriting male ascendant. Likewise, if he dies leaving a daughter and a full sister, the full sister does not receive the fixed half-share because of the presence of an inheriting descendant.

His statement, “Or for a single paternal half-sister,” means that a paternal half-sister likewise inherits one-half when she is alone. However, we add three conditions: that there be no inheriting descendant, no inheriting male ascendant, and no full sibling.

His statement, “Two-thirds is for two or more of all of these, provided that they are not made residuary heirs by a male relative,” means that two-thirds is for two or more daughters, son’s daughters, full sisters, or paternal half-sisters. But he said, “provided that they are not made residuary heirs by a male relative,” for if they are made residuary heirs by a male relative, they do not receive one-half. The rule here is that whenever one woman is entitled to one-half in a case, two or more of them are entitled to two-thirds.

The proof for this is the saying of Allah, Exalted is He: “Allah instructs you concerning
