Re: Is eating pork/jhattka Chicken/beef GUNAH-E-KABIRA
^ sure agree with that. Now lets put Quran in to perspective:
There is a Sura that says on this subject that it is Halal "as long as you believe", "again as long as you believe", "and then again if you believe" (looking up for verse and its exact translation) - This clearly states that it is OK to eat Non-Zabiha food as long as you are true believer (x3 times).
But are you? or me? or most people? - no
Staying on the same subject: There is no punishment described in Quran for eating Haram or drinking alcohol. However it is a sin.
