A man became liable for zakah but died before paying it; do his guardians pay it on his behalf?

Question:
His other question says: If a person intended to pay zakah, then died without paying it, is it possible to pay the zakah on his behalf with the intention that he is the one who paid it, as for the action?

Answer:
If zakah became obligatory upon him and he died before paying it, it is to be paid from his estate. It is to be paid from his estate because it is a debt owed to Allah the Exalted. Debts are settled before bequests and before inheritance. Allah the Exalted said: or a debt. The Prophet (peace and blessings be upon him) ruled that debts are settled before bequests. So this is a debt owed to Allah that became due in this wealth and in the liability of this deceased man. It is obligatory for his guardian after him to pay the zakah from his wealth on his behalf. Yes.
