I have a house and the state will buy it from me at an appraised value, so is it permissible to sell it now for that price?

Question:
May Allah reward you. Your Eminence, the father, the questioner says: I own a house, and the state will buy it from me at an appraised value. A person came to me and said, "Buy it from me now for its current price. If the appraisal happens in the future, I will take what you paid me, and the rest will be shared between us equally." Is this sale valid?

Answer:
No, this is not valid. This is not a valid sale with this condition, contingent on the state's purchase in the future. This is not permissible. Either you do not sell it to him, and the house remains your property until the state takes it, or you sell it to him, and he is the one who sells it to the state. Yes.
