Umm al-armal (a named inheritance case)

Umm al-armal is one of the named cases among the scholars of shares. Its heirs are two grandmothers, three wives, four uterine sisters, and eight full or paternal sisters. It is called the seventeen case, after its shares, and also the case of the feminine, since all the heirs are women. ¹

The base is twelve, rising to seventeen: two grandmothers take a sixth, two shares; three wives take an eighth of the quarter, three shares; four uterine sisters take a third, four shares; and eight sisters take two thirds, eight shares. ¹
