The Ruling on Eating the Slaughtered Animals of the Christians Who Believe in the Trinity

Question:
He says in his letter, and at its beginning: In the name of Allah, the Most Gracious, the Most Merciful. Allah, Glorified and Exalted is He, said in His Noble Book: Your food is lawful for them and their food is lawful for you, Surah Al-Imran. But as for those who take Jesus, the son of Allah, and say that He is the third of three: the Son, the Father, and the Holy Spirit, is their slaughter permissible to eat or not? Please inform us, may Allah reward you.

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, Lord of the worlds, and the final outcome is for the righteous. And blessings and peace be upon His servant and Messenger, His trustee over His revelation, and His choice from among His creation: our Prophet, our Imam, and our Master Muhammad ibn Abdullah, and upon his family and his Companions, and whoever follows his path and is guided by his guidance until the Day of Judgment.
To proceed: The questioner did not quote the verse in its exact wording. He says: Allah Allah, Glorified and Exalted is He, has made lawful for us, the community of Muhammad, the good things among foods, drinks, clothing, and other things. He has also made lawful for us the food of those who were given the Scripture. Those who were given the Scripture are the Jews and the Christians. It is said of them: may Allah have mercy on the people of the Scripture.
So their food is lawful for us. The food refers to the slaughtered animals, as Ibn Abbas and others said: their food is their slaughtered animals. If they slaughter camels, cows, sheep, or other things that Allah has made lawful, such as pigeons, chickens, and the like, it is lawful for us. And our food is lawful for them; the food of the Muslims is also lawful for them. This is all on the condition that we do not know that they slaughtered it in a manner contrary to the Shari'ah. However, if we know that they dedicated it to other than Allah, it is forbidden for us, because Allah has forbidden it when it is dedicated to other than Allah. If we know that this slaughtered animal was slaughtered for Jesus, or slaughtered for his mother, or slaughtered for their idols worshipped besides Allah, it is not lawful for us. Likewise, if we know that they strangled it without slaughtering it, it is forbidden for us. And likewise, if we know that they slaughtered it in another non-Shari'ah method, it is not lawful for us, such as the method of striking it with a pole or other means, or electrocution. This is not lawful for us. But if we do not know, their slaughter is lawful for us. If their food comes to us from their lands or they bring it to us, we buy it and eat it, unless we know that they did it in a manner contrary to the Shari'ah method, meaning they slaughtered it in a manner contrary to the Shari'ah method. Otherwise, the default is that it is lawful for us by the saying of Allah: This is the relied-upon position in this issue. Yes. May Allah reward you.
