Is it permissible to take money generated from selling Pharaonic antiquities and offer it as charity, knowing that it is part of a rikāz?

If the antiquities are of a type that is forbidden to trade in, such as idols or polytheistic symbols, then it is not permissible to sell them in their original form. Their price must be spent on public welfare and charitable causes. It is not permissible to accept a gift from the very essence of this money. However, it is permissible to give it to the poor according to their needs. If the antiquities are mixed between lawful and unlawful, then their price is mixed, and it is not forbidden to accept a gift from their seller, even if it is disliked.
