The ruling on food served by a pharmaceutical company at its event

Question:
May Allah reward you with good. This is a question sent by a female questioner from the Arab Republic of Egypt who works in the Kingdom. She says: Some pharmaceutical companies hold scientific seminars to explain the latest developments in the world of medicine and drugs at one of the hotels, and these seminars are followed by a dinner or lunch party depending on the scheduled time. The question is: Is there any doubt regarding this food in terms of the source of the money, meaning that the cost of the party is covered by the increased price of the drug, which is borne by the patient? We ask for your guidance.

Answer:
The default ruling for this food is that it is lawful, unless it is known to be from forbidden wealth, in which case it is not permissible to eat it. However, if it is not known to be so, the default ruling is that it is lawful, and praise be to Allah. Yes.
