What is the ruling on working for a telecommunications company whose applications are programmed to provide TV and internet services, 80% of which include music channels, movies, and TV series, and must one leave the job if the company refuses to transfer him to another project? And what are the implications for the past period during which he worked on this project?

It is obligatory to cease working on programming the application if its predominant use is in the unlawful, unless there is an urgent necessity. One can transfer to another department within the company that is free from doubt. The past earnings from the salary are lawful, and there is no need to dispose of them, especially for those who were unaware of the prohibition.
