“I once asked abu Ja’far (a.s.), about a man who does not pay Zakat until he is about to die. At such time if he pays Zakat in full is that acceptable? He (the Imam) said, ‘Yes, it is acceptable? I then asked, ‘If he makes a will that from one-third of his legacy, Zakat which due on him must be paid, will that kind of will be considered sufficient for his Zakat?’ He (the Imam) said, ‘Yes, it is counted as his Zakat and it is not an optional good deed when there are obligatory matters up on him.’”
