Is it permissible to eat from the slaughtered animals of a slaughterhouse where some of the workers pray and others do not, and most of them curse the Islamic religion?

It is not permissible to approve those who insult the religion in the slaughterhouse, even if they pray, because insulting the religion is apostasy that expels one from the fold of Islam. Likewise, one who does not pray, if he denies the prayer or insists on abandoning it, should not be left alone. It is also not permissible to eat from their slaughtered animals, even if they call themselves Muslims and mention the name of Allah over them. Silence should not be kept regarding them; if they cannot be expelled, Muslims must be warned against eating from their slaughtered animals.
