The ruling on the slaughter of the People of the Book if their method of slaughter is known

Question: We find many meats that have been slaughtered and imported from non-Islamic countries. Do we eat from them without thinking about the process of slaughter?

Answer: If the meats are from the lands of the People of the Book—and they are the Jews and the Christians—there is nothing wrong with it; because Allah the Exalted has permitted us their food, and their food is their slaughtered animals, so there is no barrier to eating from them if we do not know what prevents that.
As for when we know that they were slaughtered by strangling, or by striking the heads with hammers or the like, or with guns, or by electrocution, we do not eat from them. And it has reached me from many preachers that many slaughterhouses slaughter in a manner other than the Shari'ah method in America and in Europe.
So if the believer exercises caution and does not eat from these meats, that is better and safer; due to the saying of the Prophet (peace and blessings be upon him): and his saying (peace and blessings be upon him): .
So it is obligatory for the believer to exercise caution in his drink and food. If he buys the animal alive, from chickens or from sheep, and slaughters it himself, that is more preferable and better. Or if he buys it from butchers known for slaughtering in the Shari'ah method, that is better for him and safer for him.
