What is the ruling on dealing with an exhibition affiliated with a church, knowing that part of the profit goes to the workers and the other part to the church?

It is forbidden for a Muslim to engage in transactions that result in financial benefit for churches, synagogues, fire temples, and similar places of worship for other than Allah. This is because it is considered aiding their adherents in their falsehood and polytheism. Imam Ahmad prohibited leasing land endowed to a church and purchasing items sold to it.
