I posted this question earlier in the intro section, because I couldn't post anywhere else. So now I am re-posting this, hoping to get more factual answers:

aslaamoalikum,

I have a question about the Halal vs Zabiha debate.... They (people and even imaams) say halal is everything such as chicken, beef, veal, etc except pork, whereas zabiha is the actual slaughtering of the meet. My friends say its not important if its salughtered according to the Islamic Law, we can eat it as long as its 'halal' meaning as long as its not pork. Does anyone know of any specific surahs mentioned in the Quran or hadith that I can show to my friends because I know zabiha is legal way to eat, halal is not legit but i don't know where (if) it mentions in the quran to eat zabiha. Can anyone cite?
