Qurbaani & Halaal Slaughter

The slaughter of a person who leaves out Salaah

Q: Some principles that should be agreed on. (If they are wrong pleases tell me). Halaal food is extremely important. A body nourished with haram will not enter jannah. Hadeeth: Even the slightest doubt of halalness of food will render it haraam for you. We should strive to follow our religion even if its hard on us. A person who doesn't pray is a kafir. Most of the ummah think if they don't pray they are still muslim. Most muslims dont pray (Stats). Being a muslim is a requirement besides saying bismillah allahuakbar. Due to these points, I am in doubt of the food that is sold and they claim it is halaal. There is a great chance the food I eat is being slaughtered by a "muslim" who doesn't pray which puts me in doubt of its halaal status therefore it's haram for me. Does this seem extreme? Is this against the Sunnah? Please provide evidence and suggest what I should do?

P.S. I live in a Muslim country and I went to a chicken shop who slaughters the chicken on the spot. I came to know the man is known to not pray at all. Therefore I cannot trust the government which is appointed to make sure the meat is halaal. Also is it enough if the food I am eating has a halaal label on it?

Upon whom is qurbaani compulsory?

Q: I have two questions I need to ask. I was talking to my husband yesterday about Qurbaani and we had a disagreement. He told me that Qurbaani is not farz, and my belief is that Qurbani is fardh if you are working and have a steady income. Can you please clarify that for me. Also another question is about zakaat. My husband told me that we already give zakaat in the form of tax, so we don't have to give it anymore, but my questions is about the savings and all the saving plans that we have and the money that lies there, isn't it farz to give zakat on that? Please let me know. I would appreciate it very much.
