I have given this a lot of thought (couldn't sleep yesterday because of the problem). Of course I give my greatest thanks to all who gave answers to the question. In the end I came up that:
1. It is natural for us to eat animals, we have carnivore teeth. However, the way animals are treated on today's farms is absolutely unacceptable, therefore as a form of a protest I do not eat it at all. Also, moderation is important . in my household , meat is eaten nearly everyday. I hold the same belief that mass production should be possible to stop trough moderation. I think it is healthy to eat meat 2 day a week, but I'm unsure, that's what I've heard somewhere. Also I do not think that young animals that are to be eaten should be killed but at the edge of their life, but not too old, or filled with disease; because as Allah said , animals form communities like humans and I believe everyone should have a right to establish a family before being slaughtered.
2. I think that the formless one gave us an amazing choice that other animals can't make, we can choose not to eat meat; some sufis did practice vegetarianism , by the way.
Anyway, sorry for the confusion, I used to be on this forum but I harshly deleted my account because I thought I wouldn't comeback to Islam. I was wrong therefore I created another acount under the same name. Sorry for any confusions.
Peace and good day.
I am very satisfied with my conculsions, and they wouldn't be possible without this forum community , thank you!
