Is it permissible to watch Arabic films and TV series with the aim of strengthening one's Arabic language and training to speak it instead of the colloquial dialect, and are there alternatives if that is impermissible?

For it to be permissible to listen to materials that aid in learning the Arabic language, they must be free of شرعية (Shar'i) prohibitions and objectionable matters, such as musical instruments or the exposure of awrat (private parts). The Shar'i alternative to this is to listen to Arabic language learning programs and lectures available online, and to listen to religious and scientific lectures that enrich the Arabic language and are beneficial at the same time. The foundation for strengthening the Arabic language lies in the systematic study of accredited books and sources, with a gradual approach to learning.
