The ruling on selling usurped property that cannot be returned to its owner

Question : The sale of usurped property in some countries, where houses have been usurped and the government has taken ownership of them for the people, and they cannot be returned to their owners: Is it permissible for people to buy and sell them among themselves?

Answer : This is an important question, meaning the sale of usurped property that cannot be returned to its owner: Is it permissible to buy it? The answer is: If it is based on a system established by the state, such as if it says that no one owns in the residential areas except with the state's permission, and this is ownership without permission, then there is no harm. Or if his wealth was taken from him as a punishment for him, such as one who is taken for a traffic violation or something similar regarding cars at the traffic station, then it is permissible to sell it and permissible to buy it, because they will not be returned to their owners and because they were taken with a right. As for what is pure usurpation, it appears that it is not permissible.
And even if it is not being returned to its owners, one who bears its burden buys it. And because if we bought it in this case, that would be an incitement for the oppressive state to usurp people's wealth and sell it.
