Is it obligatory to repay a debt that was incurred to purchase something forbidden?

Question:
He says: Honorable Shaykh, may Allah grant you success, if a person has a debt established against him, and this debt is in exchange for something forbidden, such as taking a musical instrument or tobacco, or taking intoxicants for a deferred amount, is he required to pay it? The question is repeated: He says, if a person has a debt established against him, and this debt is in exchange for something forbidden, such as taking a musical instrument or tobacco, or taking intoxicants for a deferred amount, is he required to pay it?

Answer:
This is forbidden, this is forbidden. The price of intoxicants, the price of a musical instrument, and the price of all instruments, this is forbidden, and the sale is invalid. These matters must be destroyed; they are not money, they must be discarded and destroyed. Yes. He says: And if the one who is asking you for the amount goes to the court, you and he, the judge will see the truth. Yes, but I do not know how this question is, is this the price of intoxicants or a musical instrument? Did you buy the intoxicants or the musical instrument? I do not know. Is it permissible for you to buy intoxicants and buy a musical instrument and then ask about the value? Yes.
