Laws pertaining to the Slaughterer

Q: As a Muslim can we eat zabiha of Jews?

Q: I just wanted to ask:

1. Is it permissible to eat beef, chicken or lamb meat slaughtered by people of the book?

2. If its not halaal, then how do you interpret the verse in the Quran which says meat that has been slaughtered by people of the book is permissible for Muslims?

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?

Q: Last year I smoked marijuana 2 days before Qurbani. Was my slaughtering thus accepted or is a khaza required? Also, is it a requirement for a person slaughtering to recite all the duas including inniwajahtu or is the takbeer alone fine?

Q: Can a woman slaughter her Qurbaani animal while in the state of nifaas?

Q: Someone I know said that he consumes McDonald's which is haram in America. He says his reasoning is that this is the meat of the Ahle Kitaab and hence permissible. While I do not believe that, I do not know how to respond to him. Can Mufti saheb reply as to why this does not fall under that category?

Q: Can we eat kosher? Because I have heard that we can not eat. Can we eat with any Jew or Christian nowadays. I heard we can only eat dry fruit with them. Please answer me with proof.

Q: If a farm hand slaughters the chicken but the supplier of the chicken is a white farmer, would it be regarded as fully halaal?

Q: Is it okay for someone of the Hanafi fiqh to eat machine cut chicken? I have heard various different opinions and wanted to clarify.

Q: I follow the Hanafi fiqh and the Hanafi fiqh states that chicken must be hand slaughtered and Machine slaughtered cannot be eaten. Shafi'ee fiqh allows for the consumption of machine slaughtered chicken as long as it is done the proper way (with Kalima). In Mecca and Madina there are mostly Shafi'i followers. Is it okay for me, a follower of the Hanafi fiqh, to eat chicken when I go for Umrah/HAJJ if it is not hand slaughtered?
