What is the ruling on those who inherited money from their father, knowing the source of their father’s money and that it is forbidden money?

Al-Hawini: We know that when a man dies, his wealth passes to the heirs as lawful. So if the son or sons know that their father was a thief or stole money, and they know the source from which their father took this money; are they obligated to return this money to its owners, or does it become lawful for them?

The Shaykh : No, as long as they have known that this money was originally forbidden, and they know the place from which it was taken; there is no doubt that it obligates them to return it to its owner. Returning it to its owner is more preferable than paying off the deceased’s debt, and returning it to the creditor. Yes.
Al-Hawini: And what if it is unknown? Meaning, it is known that he loots from everywhere, but it is not known from where he took it?

The Shaykh : In that case, as we said earlier regarding the woman’s mahr, which is forbidden, and it passed to the heirs through inheritance; it is lawful for them. But if they know its source and origin; they must return it.
Al-Hawini: So, as a follow-up question regarding perfumes, he says there are beautiful perfumes from Western companies that contain alcohol. Is it permissible for a Muslim to use them, especially since oil-based perfumes are mostly expensive and many people cannot afford to buy them?

The Shaykh : There is nothing new in this question on the subject except thatThe questioner : the questioner complains about the high price of oil-based perfumes , as for the answer, it has been mentioned before: if there is a large proportion of alcohol in them; then selling them, buying them, and using them as perfume is forbidden.
Yes.
