Is working as an accountant in an art production and distribution company (songs - films) - in addition to a large department for Islamic production and distribution - unlawful, and is the income earned from it unlawful?

It is impermissible for an accountant to work for a company that sells forbidden films and music, even if he is not directly involved in the buying and selling, because by doing so, he is assisting in sin, which Allah has prohibited with His words: "And do not cooperate in sin and aggression." And just as the scribe of usury and its two witnesses were cursed, despite being mere assistants, so too is assisting in falsehood in any form unlawful. However, if the accountant's work is limited to the revenues of the Islamic section, then there is no harm in that.
