What is the ruling on working for a land transport company that leases its trucks to a company that produces alcohol for its transportation?

It is not permissible to work in a company that deals with alcohol, due to the Prophet's (peace and blessings be upon him) curse upon all that is related to it. However, if the work is restricted to transporting permissible goods, then there is no harm in it. Nevertheless, it is better to seek employment where all tasks are permissible.
