The ruling on the debt of a deceased person to an unknown creditor

The questioner:
In the name of Allah. You are asking about a person who passed away.

The Shaykh:
How so? He had a debt, and the creditor is unknown. It is known that he was owed six thousand riyals. I do not know this person. He asks about the paper merchant. His goal is the poor. He asks the heirs? He has no heirs. Who is he? His heirs are his children, because... except for the creditor. He is unknown. And there is no proof, no... And it is known that he receives a sum of six thousand riyals from a person, but he passed away and did not disclose the name of this person, and he was not identified. Except that Allah knows. Give the money in charity, if they are poor, it is a place for charity, give it in charity with the intention of the creditor. And if the creditor comes and they identify him, they give it to him.

The presenter:
Now, what is the ruling on worn gold, O Shaykh? Is there zakah on it?

The Shaykh:
I heard you pass the question.

The presenter:
I found it now.

The Shaykh:
There is zakah on it, yes, if it reaches the nisab, according to the correct opinion. Professor.
