Haraam Food & Drinks

Halaal and haraam meat

Q: I would like to know about meat or chicken for selling in non-muslim shops cooked or uncooked. Are Muslims allowed to buy that meat or chicken?  Can Muslims go to Mcdonalds in non-muslim countries? I heard that chicken can be halaal for Muslims living in western countries to eat in Mcdonalds and to buy in non muslim shops because chicken don't have a lot of blood compared to other animals. Is this true? How can I know which meat is halaal and which haraam while living in a western country? I am really confused about this matter and it makes it hard for me to chose the right food. Can you please explain this to me?

Bone broth

Q: I am researching the use of bone broth and I need to know if is permissible. It is a soup type of dish which is jelly in form after many hours of boiling and also a type of gelatin. If so, are all parts of the bones permissible for use, particularly bone marrow? (except the organs from which we are forbidden to use and eat). It is used for stomach lining healing.

Consuming haraam

Q: If a person were to consume haraam food eg. a chocolate without any doubt or without knowledge that it contains haraam, would a person's imaan be weakened? Similarly eating take aways.

Attending the da'wat of someone whose major income is from haraam

Q: My question is that some of my relatives live in UK where they work in different sections such as the sale and making of Alcohol. They send their
income to Pakistan. That money they use for their house hold usage. Now they are getting their daughter married and when we go to meet her, we are invited for dinner. The problem is that is their income is halaal and we can eat food or other things from their home or not? Is it halaal for us, because we know about their income is from haram sources. In uk it is halal but in Pakistan it is Haraam?

Sucking blood

Q: I wanted to inquire about the drinking of flowing blood being haraam! If a person checks his sugar, pokes bimself for the blood to be released and
thereafter sucks the remaining blood from his finger, is this constituted as haraam?
