Slaughtering should meet four conditions:Firstly,
the slaughterer should be legally responsible and competent for religious commitments, i.e. he should be sane, whether a Muslim, a Jew, or a Christian.Secondly,
regarding the tool, it is permissible to slaughter the animal with any sharp tool except bones and hoofs, because the Prophet (peace be upon him) said,
"If the killing tool causes the blood to gush out, eat (of the slaughtered animal), but do not slaughter with a bone or a hoof."
(Agreed upon by Al-Bukhari and Muslim)
cutting the throat even if at the upper part of the neck, which is the air passage, and cutting (Part No. 22; Page No. 354) the gullet, which is the passage of food and drink.Fourthly,
the slaughterer should begin with the name of Allah alone, and nothing can replace it. If he forgets reciting Tasmiyah (saying, "Bismillah [In the Name of Allah]"), the slaughtered animal is lawful; but if he left it on purpose, the slaughtered animal becomes unlawful.The Committee lists these conditions to make it easier for you to know when the slaughtered animal becomes lawful and when it does not become lawful. Accordingly, it is lawful to eat from the animal in question.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
