The Ruling on Eating the Slaughter of a Disbeliever and the Effect of Intention

Question:
And if one does not know the intention of the one who slaughters—whether he is seeking trade or seeking nearness to Allah through patience or otherwise—and if one does not know whether he intends to invoke the name of Allah and His Messenger, and whether it is permissible to eat the slaughter of one who dies without evidence,

Answer:
It is not permissible to eat the slaughter of a polytheist or an apostate. This is with regard to the slaughterer: it is not permissible to eat the slaughter of a disbeliever, even if he says "In the name of Allah" and slaughters it in the prescribed manner, due to his lack of eligibility. Only the slaughter of a Muslim and the slaughter of the People of the Book are permissible, , meaning for one who preserves the Book and the Muslim. As for the disbeliever in all his types—whether idolater, atheist, or apostate—their slaughter is not permissible because they are impure, and this has an effect on the slaughtered animal. It is not permissible to eat the slaughter of a disbeliever. As for one whose outward appearance is Islam, whose outward appearance is Islam and we know nothing of disbelief or shirk (associating partners with Allah) about him, the original ruling is permissibility. The original ruling for a Muslim is permissibility, unless it is established for us that he is an apostate, or that he is a polytheist, or that he calls for aid from the dead or slaughters for graves. In that case, his slaughter is not permissible if this is established about him. And if he is suspected but nothing is established against him, the original ruling is permissibility. However, if you leave it off to avoid doubts and leave what is doubtful, that is good. Yes. And Allah the Exalted knows best, and may Allah send prayers and peace upon our Prophet Muhammad and upon his family and companions.
