Scimitar, brother, you said you have never seen a doctor earn Halal. Which country do you live in? I don't really know how you can say that, your exposure to the medical side must be less.
Coming from a family of doctors, I have never seen a doctor earn "Haram". My dad is a Consultant in Cardiac Anaesthesia, and has been doing this since the past 30+ years, and is near retirement, and so far I have never seen him earn a single Taka or Riyal Haram. He has worked in the best Cardiac hospital of my country since day 1, and I have never seen either of his friends earn Haram like you are mentioning. Worth noting, Cardiac Anaesthesia is the highest level of Anaesthesia and he and his colleagues and all those doctors of his age are the senior most working doctors of my country and I have never heard any of them earn Haram. I have simply no idea in which country you live, that you claim all of the doctors are earning Haram and are drug dealers in disguise. I totally "disagree" with you, 101%.
Your exposure to doctors must be highly limited or else there's no way you can say such a thing.
Yes, there are some black sheeps in every community, but that doesn't define the majority.
Majority of the doctors, whether Muslim or non Muslim, earn Halal.
I am not here to defend Medicine, am not at all interested in it, I work in the Aviation industry, but I have to be honest. I have never seen my dad earn Haram, neither his colleagues, in several countries of the world where I lived, including Bangladesh, India, Malaysia, and Saudi Arabia.
Care to elaborate why you have too much hate for doctors? Lol.
