is it permissible to work in a pharmacy, even though it may sell alcoholic/tobacco products? What are some examples permissible halal jobs, or which the money earned is halal?

Working at a pharmacy is Halal and allowed. What Muslims Iknow do is that they kind of have a mutual agreement with their supervisors to ask a non Muslim co worker to ring up the customer who is buying alcohol. As long as you try your best to avoid the transaction by all means, then you are okay. Halal jobs are jobs that basically don’t sell or provide services to people that are considered prohibited in our faith. please find the verdict on selling Alcohol issued by AMJA(Assembly of Muslim Jurists of America)
