What is the ruling on working as a security guard in major hotels in the Gulf countries, and on eating and drinking from these hotels, knowing that the work is affiliated with a private security company and the salary is received from it?

Your work is permissible as long as it does not involve anything unlawful, such as attending or assisting in a forbidden act, for Allah Almighty says: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." Eating and drinking become unlawful if it is without permission, or involves something forbidden, or necessitates participation with someone consuming something forbidden, or if it is part of the salary for unlawful work. In this case, it must be abandoned immediately.
