Business and Dealings

Q: My question is a regarding business.

I have a store and sometimes I get some guys to buy from me goods for their organisation. (I have no idea who they are funded by). They will only bring to me business if I give them commision. So what I do is if I am selling something for 5000, I quote them 5500. After quote is accepted they give me 5500 and from there I will give them 500 as commision. I want to know is this a halal method? If not can you explain to me in detail a halal way so that we can carry on with business in our shariah way and follow the sunnats of our Prophet Muhammad (Sallallahu Alaihi Wasallam).

Q: Is it permissible for a Muslim to take loans for their business or making homes of  their own?

Q: I am planning on buying a new house that costs $250,000. However, I do not have enough money to pay the full amount up front and I do not want to pay interest on the house. The deal I have worked out with the company selling the house is that I will pay $300,000 for the house but I will not pay any interest. Meaning, I will pay $2,000 every month for 150 months for a total of $300,000. This way the company will make some money on the house and I will not pay any interest.

Is this a permissible deal for me to make?

Q: Say, suppose, I had borrowed some money from a certain person (not specific) about few years back. When I return the money to him, do I return the exact amount or should I include some extra amount accounting for the inflation that would have occurred during the years. Would including the extra amount mean I am giving interest and would it be a haram?

Q: I'm a sister with 6 kids. I live in usa and my husbands earnings are haram. He has stores that have alcohol and lotto, some pork items and some drug items and food as well, and he imports illegal cigarettes. Can I report him to the authorities about his illegal sale of untaxed cigarettes so they can strip him his licence for the alcohol and lotto and cigarettes so that our store can be halal. At least he'll reflect and can't return those licence. Can I do this for the sake of our income and spirit because he would not listen to me. He loves the flowing of the money and doesn't care where it's coming from.
