Brief Explanation
(Commentary on Ahadith 3229 to 3231)
Khums means one-fifth, and rub‘ means one-fourth; that is, they used to make a bequest (wasiyyah) of less than one-third. And in their view, one-third was the limit of disobedience, meaning that making a bequest of more than this was considered prohibited. And Allah knows best.
