- Is naming over the slaughtered animal an obligation (fard)? - Is it permissible to eat from the sacrifices of the People of the Book if they slaughter them for God and offer the meat to churchgoers, similar to what common people do at the mawlids of saints, bearing in mind that mentioning other than God over the slaughtered animal renders it carrion? - What are the easiest forms of slaughtering, and is it done by cutting the windpipe, esophagus, and jugular veins from the front? - Is it permissible to slaughter using automatic slaughterhouses, and can God's name be recorded on a tape that is played throughout the period of automatic slaughter?

1. Invoking the Name of Allah (Tasmiyah) during Slaughter: It is obligatory according to the majority of jurists (Hanafis, Malikis, and the well-known position of Hanbalis), and it is waived if forgotten. The Shafi'is and one narration from Imam Ahmad consider it a sunnah (recommended). Audio recordings of the tasmiyah are not sufficient; the slaughterer must utter the tasmiyah himself.

2. Method of Slaughter: The most complete method is to cut the trachea, esophagus, and both jugular veins. Scholarly opinions differ regarding what constitutes sufficient cutting, and this divergence stems from the absence of a definitive sunnah on the matter. It is inferred from the hadith, "Whatever causes blood to flow, eat it," that blood effusion occurs by cutting the jugular veins. The place of slaughter is the throat and the labba (the hollow between the base of the neck and the chest); it is impermissible to slaughter elsewhere, by consensus.

3. Islamic Slaughter (Dhabiha): It is considered the least painful method of killing an animal and the best for blood drainage. Kindness in slaughter and providing comfort to the animal is obligatory, as stated in the Muslim hadith: "Indeed, Allah has prescribed ihsan (perfection/excellence) in all things. So, if you kill, kill well, and if you slaughter, slaughter well. And let each one of you sharpen his blade and relieve his sacrificial animal." Experts believe that slaughter is a means of bleeding the animal, similar to blood donation, and it acts as a type of anesthesia that reduces pain.

4. Mechanical Slaughter: It is permissible if the aforementioned legal conditions are met. The slaughterer must utter the tasmiyah himself at the time of slaughter, whether it is done manually or mechanically.
