The maximum shares of mother and widow under Sunni Law of inheritance may be

Under Sunni law the mother's largest Quranic share is one-third (when there is no child or son's child and not more than one brother or sister), and the widow's largest share is one-fourth (when there is no child or son's child); with such descendants they take one-sixth and one-eighth. The correct pair is therefore "1/3 and 1/4"; the other pairs give a reduced share or a share, such as one-half, that belongs to other heirs.
