Rules about Leftovers of Household Expenses

2. A number of our people have narrated from Ahmad ibn Muhammad from Ibn Abi ‘Umayr from certain persons of our people who has said the following: “He once asked abu ‘Abd Allah عليه السلام, about a man who leaves one thousand dirham for the expenses of his family and it remains with them for one complete year is there Zakat on it? He (the Imam) said, ‘If he stays Zakat is due, but if he is absent, Zakat is not due on it.’”
