I am not very sure if the KFC chicken in Bangalore is 100% halal.
I have noticed that many meat sellers in Bangalore are muslims and hence the meat they sell are almost always halal meat.
"One of the following three scenarios must apply to this meat:
1 – We know that it has been slaughtered in the proper manner. This meat is halaal.
2 – We know that it has not been slaughtered in the proper manner. This meat is haraam.
3 – We are not sure; we do not know whether it has been slaughtered in the proper manner or not. The ruling in this case is that the meat is halaal, and we do not have to ask about how it was killed, or whether the name of Allaah was mentioned over it or not. Rather it seems from the Sunnah that it is better not to ask or try to find out. Hence when they said to the Prophet (peace and blessings of Allaah be upon him), “we do not know whether they mentioned the name of Allaah over it or not,” he did not say to them, Ask them whether they mentioned the name of Allaah over them or not, rather he said: “Say the name of Allaah over it yourselves, and eat it.” This tasmiyah or saying of the name of Allaah which the Prophet (peace and blessings of Allaah be upon him) told them to do is not the tasmiyah of slaughter, because the slaughter is over and done with. Rather it is the tasmiyah of eating, because what is prescribed is for the person who is eating to say the name of Allaah when he eats. The correct view regarding saying the name of Allaah when eating is that it is obligatory, because the Messenger of Allaah (peace and blessings of Allaah be upon him) enjoined it, and because if a person does not say the name of Allaah, the Shaytaan shares his food and drink.
If a person wants to be cautious and forego eating this meat, there is nothing wrong with that, but there is also nothing wrong with eating it. "
