What is the ruling on money earned from preparing projects, programs, brochures, and school assignments for students and others, and what should one do if this money was unlawfully gained?

There is no harm in carrying out tasks required for websites, brochures, programs, and school projects. However, research papers that students are asked to complete themselves should not be undertaken by others on their behalf, because that is forbidden deception and a type of betrayal. There is no harm in seeking assistance from others, but not to the extent that the entire message is the work of someone else.
