Is it permissible to work as a manager for a flower selling company, knowing that there is selling for infidel holidays and dealing with banks and hotels to decorate their premises for occasions and weddings?

It is permissible to work in the management of a company that sells flowers, provided that they are not sold for polytheistic occasions or to those who would use them for unlawful purposes, such as decorating riba-based banks or celebration halls. This is because selling something that aids in sin is not permissible, as Allah Almighty says: "And do not cooperate in sin and aggression." However, if they are used for permissible purposes, then selling them is allowed.
