What is the ruling on working under a freelance system, and what are its permissible and impermissible aspects, especially in the fields of graphic design, creative writing, research, and web development?

It is a grace from Allah upon people that He has broadened the gates of the permissible and narrowed the gates of the forbidden. The principle in dealings is permission unless there is evidence to the contrary. There is no objection to working in freelance fields such as graphic design, writing, narration, research and development, and creative, cultural, or educational works, provided that they carry a meaningful message, such as bringing joy to people, instilling the values of truth and guidance, or educating them. If you consider these meanings, the fruits of your labor will be good, and your creativity will follow this high moral trajectory, far from partial prohibitions.
