Fulfilling a Vow on Behalf of the Deceased

Question:
If the one who made the vow dies, is it obligatory upon his guardian to fulfill his vow?

Answer:
If a person dies and has a vow, if he dies and has a vow, and this vow is financial, such as slaughtering a sacrificial animal or giving charity, a financial vow, and he has an estate, it is executed from the estate before inheritance; because this is a debt to Allah, and debts are paid from the estate before the bequest and before inheritance, so the vow is executed from the deceased's estate.
Based on his saying (peace and blessings be upon him): "Pay off the rights of Allah, for Allah has the most right to be paid." As for if the vow is not financial, such as fasting, Hajj, or 'Umrah, then his guardian performs it on his behalf, based on his saying (peace and blessings be upon him): "Whoever dies with fasting remaining, let his guardian fast on his behalf," and in another narration: "Whoever dies with a vowed fast remaining, let his guardian fast on his behalf," because this is a bodily act of worship, and money is not sufficient for it, meaning that fasting is not compensated by charity, so his guardian performs it on his behalf.
