Is providing educational services to university students—such as helping with graduation projects, explaining their details, giving lessons, and executing work—for a fee, permissible (halal) or questionable ( فيه شبهة )?

It is permissible to assist students with their graduation projects and to give them lessons on how to prepare them, and the payment for that is lawful. However, it is not permissible for the assistant to do the project and for the student to present it as their own work, due to the forbidden deception involved therein according to Islamic law. Rather, the assistant's role should be limited to guiding the student and teaching them how to complete the project, and supervising them until the student is able to prepare it themselves.
