What is the ruling on an employee participating in a commercial venture as a financier, or in a commercial venture that does not require a trade name, such as distributing a product, and does the state system in Saudi Arabia prohibit that?

Originally, it is permissible to work and earn a living in permissible ways, as the Sharia (definition) has urged Muslims to strive to acquire sustenance, as long as the work does not result in harm to the Muslim, based on the Prophet's (PBUH) saying: "There should be no harm nor reciprocating harm," and "It is not befitting for a believer to humble himself" by exposing himself to affliction beyond his capacity. Regarding the work system in Saudi Arabia, it is advisable to consult the scholars there.
