Is the money of a guardian who works as an accountant in the Radio and Television Union, which is affiliated with the Ministry of Information, and through whom pass receipts and papers for matches, TV series, and films, considered unlawful money, and what is the ruling on the one who benefits from this money?

There is no blame upon you for benefiting from what your father spends on you. The fundamental principle regarding a Muslim's wealth is that it is lawful. You are not required to investigate the source of his wealth unless you know with certainty, or it is highly probable, that his work involves directly engaging in unlawful matters. In that case, the unlawfulness in his earnings would be proportionate to the forbidden actions he performs. If you wish to discuss the matter with him, do so with wisdom to clarify the impermissibility of assisting in unlawful matters. However, you are not obliged to avoid his food or dwelling.
