The Slayer Must be Muslim

Slaughtered by Nawasib
Question :

According to Shia jurisprudence, we are not permitted to eat meat of a lawful animal if it was slaughtered by Nawasib. Are we allowed to eat meat of animal slaughtered by "Wahabis” and “Salafis" since they hate Imam Ali (peace be upon them)?

Answer :

If they hate the Ahlulbait (Peace be upon them) then their slaughtered animal must be avoided based on compulsory precaution; but if they hate the followers of the Imams of the Ahlulbait without hating the Imams (peace be upon them), then it allowed to consume their slaughtered lawful animal.

Non-Practicing Butcher
Question :

If a butcher is a non-practicing Muslim, i.e. he does not offer prayers and other obligations and refrain from prohibited things, and I know that he does not observe the conditions of slaughtering, such as placing the animals to face Qibla and reciting the Name of Allah, is his meat permissible?

Answer :

If the butcher knows that the animal must face the Qibla when slaughtered and he does not observe such a condition deliberately, then the meat of the animal is not lawful to consume. If he forgot to do so or he did not know that this is a condition, then the meat is permissible to consume.
If the butcher forgets to recite the Name of Allah when slaughtering the animal, then it is lawful to consume the meat. If he did not do so deliberately or out of ignorance, then the meat is unlawful to consume.
