shares

Respected scholars, as-salamu `alaykum. My question is very basic. Is buying shares in a company that deals in essentially halal products (e.g. agriculture) but also engages in interest bearing activities such as taking bank loans considered halal? Thank you for your time.

Is it halal to purchase shares of conventional banks? I have read many articles and islamic decisions on this but there are cloudy directions as to the consideration of the  percentage of the halal or usury earnings of the company, their percentage of forbidden assets, and thier involvement of in other businesses and also thier percentage of interest based deposits and so on. Please give me a concise and direct fatwa on this issue of buying shares of conventional banks. I really need an answer. Jazakallahu khairan.

Asalam Aleikum My Mother bought shares in a non-islamic bank, before we knew it was haram? Now we know it is, how do we go about rectifying this sin? Just selling the shares?thanks for all the work you are doing. We are learning a lot

What is the Islamic ruling regarding buying shares and selling them in the same day?
