Q: I would like to ask whether is it allowed in Islam to sell anti-alcohol products/medicines, which works as an antioxidants to prevent liver and other side effects of alcohol including losing consciousness, disturbed sleep?

Q: Is it permissible to buy bank repo vehicles as well as buy from bank auctions? What is the Shar’ee ruling regarding ownership of the repossessed vehicles and items? Does the bank own them after they are repossessed?

Q: I invested in cryptocurrency last year. What is the Islamic ruling regarding cryptocurrencies? If it is not permissible, what should I do with it?

Q:

1. Hermes is a fashion brand and its name was taken from a Greek figure. However, the bags do not have the Greek symbol for Hermes. Is it permissible to sell the bags anyway? What I mean with Greek figure is Greek 'god' (their words, not mine).

What about selling Louis Vuitton bags or Jordan Sneakers. Their name doesn't represent a 'god'. Just a person. 

2. My second question is about day trading. First of all, is day trading stocks (non-haram businesses) permissible. And what about day trading crypto. So, trading ARK for BTC. Both are cryptocurrencies. Is this trade a form of riba because it seems like it is a 'gold for gold' trade (both cryptocurrencies, but they have different values and meanings).

3. You said that investing in halal companies is permissible, however the interest that they are involved in is totally forbidden. But does that make my earnings forbidden (and does it come in the category of 'witnessing riba')? 

Q: Is growing tobacco halaal or haraam in Islam? Will the income received from selling tobacco plants be halaal or haraam?

Q: I have read somewhere that it is better to avoid wearing Nike, because it symbolizes a 'Greek mythical figure' (if you know what I mean). But what about selling the shoes.  Because Nike and Jordan are amongst the best selling shoes.

Q: Is day trading in cryptocurrencies halal? Day trading basically means buying and selling your shares within a day. Note, I have knowledge concerning this subject and for me it is not like gambling. What I do (and almost everyone else does) is checking the chart and based on the chart's movements, I make a decision whether or not it could be a good trade. However, what made me doubt the legitimacy was gharar and maysir. I have done so much research about these terms and it still remains kind of unclear whether it is a form of gharar and/or maysir.
