Is ghostwriting or white-label work halal?
Ghostwriting is generally permissible. You are selling your labour and transferring the result to a client who then owns it, which is an ordinary service contract - and the practice is old, well established and openly acknowledged in publishing, speechwriting and corporate communications. Nobody is deceived when a chief executive's article is drafted by a communications team, because readers broadly understand how such pieces are produced. The question turns on whether anyone is misled about something that actually matters to them. Two situations cross that line clearly. Academic work submitted as a student's own defeats the purpose of an assessment and deceives an institution that is certifying competence. And professional output where a qualification is being relied on - a legal opinion, a medical article, an engineering report - misrepresents whose expertise stands behind it, which is exactly what the reader is relying on. Everything else sits between, and the useful test is whether the reader would feel deceived if they knew.
