Question
There are some slaughterers who have no religion, and they may insult the religion or the divine essence. Is it permissible to accept their slaughter?
Answer
I say, and may it be successful: If he has no religion, it is forbidden. If he insults the divine essence, he becomes an infidel unless he repents and utters the testimony afterwards; then it is permissible to slaughter him, otherwise it is not permissible. And Allah knows best.
