Is it permissible to take money from a father who works in farms dedicated to the production of alcohol, to use it for trade as a gift or a loan, knowing that he is the family's sole provider?

Working in a grape farm whose produce is designated for wine production is considered cooperation in sin, and its earnings are impermissible. It is permissible for a child to take from his father's money earned from this work if he is in dire need of it, especially if all of his father's money is unlawful. However, if the money is mixed with both lawful and unlawful earnings, he is permitted to benefit from it even if he is not in dire need.
