Is it forbidden or permissible to finance parties that involve intermingling, dancing, and unlawful gatherings, even if the food and drink are permissible?

Mixing of genders (ikhtilat), singing, music, and dancing are all forbidden in Islamic law. It is not permissible to assist anyone who organizes parties that include these activities, as Allah Almighty says: (And cooperate in righteousness and piety, but do not cooperate in sin and aggression). The money earned from these parties is ill-gotten, and its owner must repent from it, for the Prophet, peace and blessings be upon him, said: "No flesh nourished by unlawful gain will enter Paradise, and any flesh nourished by unlawful gain, the Fire is more befitting for it."
