Is it sufficient to mention the name of Allaah
    over any meat?
Question

                If I buy meat that i know has not been
      killed islamically, is it ok to mention Allahs name and eat it. I read a hadith in sahih
      Al Bukhari where certain people were unsure whether the meat they had was halal and the
      prophet (saw) told them to mention Allahs name. Is that the correct understanding of the
      hadith?
Praise be to Allah.If it is not known how the meat was slaughtered, but it
    is thought that it was most likely slaughtered in the Islamic manner, because it comes
    from a country where most of the people are Muslims or People of the Book, then it is
    sufficient to mention the name of Allaah when eating. But if it is known that it was
    slaughtered in a manner that is not Islamic, then it is not permissible to eat it, because
    it comes under the ruling of maytah (dead meat), and Allaah says (interpretation of
    the meaning):
“Eat not (O believers) of that (meat) on which Allaah’s
    Name has not been pronounced (at the time of the slaughtering of the animal)”
