What is the ruling on my job of transporting newspapers and magazines that publish indecent pictures, knowing that my role is limited to delivery and I do not have the right to object to their content?

It is not permissible to engage in such work or consider it a means of earning, because it falls under cooperating in sin and aggression, which is forbidden by the Almighty's saying: "And do not cooperate in sin and aggression." It is obligatory to abandon this work and dispose of any remaining money from it.
