Asalmualaikum, I have 2 questions
1- I live in USA, and American Islamic scholars have created a website regarding halal food, which is 411halal.com, everything which is available in market like most of the chips, all energy drinks and a lot more, is haram according to that website. I am a student and need to eat outside, is it possible that you can tell me the ingredients which make the food haram. For instance, redbull, I search for all the ingredients which redbul cotain, and I coulnt across any thing which come from non-vegetable.
3- I want to know that after knowing that certain products are haram like redbull and if still I consume it, is it a biggest sin. I tried to search for its ingredients and couldn't find anything haram in it, and I started drinking it back. Is it wrong?
2- I want to know, consuming how much alcohol is haram. Most of the food or medicine contains certain % of alcohol, which obviously can't make dizzy. Is alcohol as haram as pork, I mean consuming even .0001% is also haram?
