Is it allowed to work as a bartender or a steward in a bar that serves alchool?
I want to know whether it's haram or halal or makruh and what argument back this "fatwa".
Working as bartender/steward means in the end that part of your work is serving/transporting/selling alcohol - people doing this are cursed according to this hadith:
Al-Tirmidhi Hadith 2776 Narrated by Anas ibn Malik
Allah's Messenger (saws) invoked the curse of Allah on ten people in connection with wine: the wine-presser, the one who has it pressed, the one who drinks it, the one who conveys it, the one to whom it is conveyed, the one who serves it, the one who sells it, the one who benefits from the price paid for it, the one who buys it, and the one for whom it is bought.
I am no Alim but: Yes, IMHO it is haraam to work as bartender/steward if alcohol is part of it.
Further reading you might find interesting:
Whatever you are doing is not considered here, But the result that your action may reflecting are strictly prohibited by Islam. That is it may help someone to take alcohol. More than that the money or profit that you are payed from that bar/shop is also made\earned from haram. So it is not good to have a job in bar\ something like that.
Hope this helps. Include me in your Dua. :)
