What is the clear detailed ruling on associating with singing and singers, acting and actors, and being influenced by them?

It is known that the terms 'singer' and 'actor' are usually only applied to those who practice these professions, including what is contrary to Islamic law. Therefore, it is not permissible for a Muslim to associate with someone who professionally practices unlawful singing and unlawful acting. It is also not permissible to be influenced by or admire people of immorality and foolishness, because whoever admires or is influenced by them is either pleased with their actions or supports them in what they do, and that is something Allah and His Messenger are not pleased with.
