What is the ruling on the action of a father who molested his daughter's friend, and what is the ruling on revoking the general power of attorney granted to him, and is the daughter sinful for this, and what is the correct course of action regarding these repeated behaviors, given the feeling of insecurity and linking this to demonic possession?

If the father consumes intoxicants and abuses women, the questioner should exercise caution in dealing with him and take measures to prevent these actions. However, his right to dutifulness (birr) and good companionship does not fall away. Part of showing dutifulness to him is enjoining him to good and forbidding him from evil gently, and helping him repent.

Regarding the properties he registered in her name: if he registered them to her for the purpose of pretense (talji'ah), then they belong to him. If he gifted them to her, he has the right to revoke his gift.

As for the questioner's private funds: there is no harm in her canceling his power of attorney over them, and she is not obliged to give him anything from her money as long as he has sufficient means. If the father mismanages his money and spends it on forbidden things, it is permissible to refer his case to the ruler (judge) to place him under interdiction.
