Thanks for the reply, but I got some questions.
I read this in the link you gave me.
"Question: What is the ruling on a Muslim working in a restaurant in which he must serve alcoholic beverages?
Answer: It is not permissible to do anything in connection with alcoholic beverages."
"Q: Question: A person works in a grocery where he works as a cashier.
His job is to scan the products which people want to buy. The products are e.g. pork, non-halal meat and alcohol and so on.
Is it permissible?
A: His income is halal but he should not deliver or sell alcohol. If he sells other items mainly but sometimes alcohol is also a tiny item within the goods sold, his income would still be halal."
I don't get it?? 1 of quotes says you shouldn't have anything to do with alcohol, the other says it's halal for a cashier.
Can you help me? I myself am a cashier, but I do also put some haram items on the shelf. Is my income halal? And what does Khamenei says about it? all links were Sistani.
