Investments and shares

Q: There is an investment company. The company sells sand for building purposes and transports people in busses. You can choose anyone you like to invest in. I chose of sand, then the chairman gave me form to fill, I filled, and I invested the sum of 100, 000 naira. Then the chairman signed the form that after 13 months I should come and collect 230, ooo naira both my capital and profits. 100, 000 naira my capital and 130, 000 naira is the profits. I shouldn't collect until on fixed signed date and amount fixed in the form at the beginning. They wouldn't charge me for any loss or accident when happens during the transaction because they have registered in insurance company, the insurance company will handle any losses. And the amount of profits the chairman of the company wrote down in the form at the beginning is the exactly what l should get after the date of agreement comes. Is this halal? What is your view?

Q: I had a question regarding finance in islam, specifically investing in cryptocurrencies. I understand that it is only halal to invest in companies that do not deal with any haram acts such as interest or alcohol. However, I was curious to know, if company A, for example, is completely halal in its goals but is partnered with company B that is not halal such as a banking company, is it still halal to invest in company A?

I had a friend call a local sheikh who stated that it is halal to invest in company A since the goal of the company itself, for example to build an education platform, is completely halal even though company A is partnered with company B that is not halal. I just wanted to verify this information with another sheikh to put my mind at peace since I do still have some small amount of doubt.

Q: My question is about bonds issued by the state bank of Pakistan. I want to know whether investing in bonds is halal or haram. Remember, there is no interest amount charge on it. If your name is in the list of lucky draw you will get a specific amount/money after tax deductions if not then you will get back tbe face value of the bond. So tell me whether investment in such thing is halal or haram?
