What is the ruling on a daughter taking financial support from her father who works in social insurance, while she does not know whether his money is lawful or unlawful, and is it permissible for her to eat and drink in his house?

Working in governmental social insurance is permissible because it is a cooperative and permissible insurance, not a commercial insurance that aims for profit. Rather, it is a general insurance that aims to assist individuals in cases of disability, old age, and illness. The state is obligated to care for its citizens, and there is no harm for the daughter to benefit from her father's money, given that he works in social insurance.
