Ruling on eating meat slaughtered for other than Allah

Question:
The questioner says in the noble verse: [Al-Ma'idah: 3] to the end of the verse... She says: On one day, I ate meat that had been slaughtered for other than Allah, and I did not know that it had been slaughtered for other than Allah. I did not find out until later from one of the neighbors, where that woman had invited some people, and I went to them and ate this meat with them. I did not know whether the name of Allah was mentioned over it or not, but I ate it. Please direct me in my question.

Answer:
If the one providing the meat is a Muslim, or from the People of the Book, then there is no harm in a person eating it, as long as he does not know that it was slaughtered for other than Allah, or that the one who slaughtered it intentionally left off the name of Allah.
As for if the name of Allah was left off due to forgetfulness or ignorance, that does not harm. You may eat from the meat provided by Muslims, because the original state is purity, and it is not befitting to suspect Muslims.
However, if a person knows that this slaughtered animal was slaughtered for other than Allah, for idols, or for the people of graves, or for the jinn, it is forbidden. It becomes carrion, and it is not permissible. As for it being the slaughter of a Jew or a Christian, Allah has permitted their food to us... The food of the People of the Book is for us, yes, except if we know that it is forbidden. If we know that they slaughtered it for other than Allah, or intentionally left off the name of Allah over it deliberately, while they know the ruling of the Shari'ah.
The point is: that there is no blame in this, for a person to eat from the meats slaughtered by Muslims, or by the People of the Book, as long as he does not know that there is a legal impediment to it.
