Re: have you ever eaten haram food by mistake?
nope but one of my friend did ... in fact we figured that on the day he took all of use to that food stall. He used to tell about "egg rolls" at a Mexican food stall (Irvine, CA). So one day we all went there for lunch and as my normal practice I just checked with the cook if they use any meat or meat stock in these "egg rolls" and answer was YES, "ham stock" :D
Friend who almost used to have it every 2nd/3rd day vomited right there even though we had not eaten any food yet.
