Investments and shares

Buying shares in a company where 5% or less of the company investment is in haraam activities

Q: In order to buy stock shares, I have seen a ruling that says that only 5% or less of a company investment should be in haraam activities like alcohol, interest, etc. How can we say that when Allah has asked us to completely stay away from them? Will investing in Islamic banks be halaal if they follow these guidelines?

Investing in an electrical store

Q: I am from a Muslim country. I am planning to invest in a business with a friend in which the friend of my father repairs electronic equipment like fans, washing machines, ovens, irons, etc. and also installs electricity in newly built houses and sells electric items.

My question is that is this type of business halal as we provide our service and the user of all these things will use them for some haraam things like they will watch movies, listen to music and this kind of stuff. In general, is an electric store business permissible?

Selling one's share in the stock market

Q: I am an active stock investor, My question is that I invested in a company which was halal almost 2 years ago but as of now, it's interest bearing debt is 71.2% and before it was halal because it's interest bearing debt was less than 30% of it's market capital. I use a stock screener which showed it was halal.

So, what should I do in this case as it was halal at the time of investing; Should I sell it with profit because it was halal at that time? Should I sell it with no profit? or keep the stock in my portfolio until it becomes halal again?
