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.

Q: If anyone wears gems like ruby etc. some people think it will bring good luck etc. is it permissible to sell this sort of stuff as we may be just selling it for luxury purposes but on the other hand people may be misguided.

Q: I want to sell gems and precious stones. Kindly advise if it is ok to sell in Islam.

Q: I'm doing business of non alcoholic perfumes and Attars. The fragrances, which I sell come from a company in india (total hindus), keva fragrances. This company also uses synthetic animal derivatives such as civet oil, etc. in their perfume oils. They said, we can give halal declaration of any product, but did not show any halal certification. 

Secondly, this company is partly owned by blackstone, a giant company of USA, which deals in real estate, credit, equity, etc. involving interest as well. My question is that whether it is preferable to sell their products to earn, as they are strict Hindus and might be involved directly or indirectly in interest also. Secondly, the use of synthetic animal derivatives in fragrances are halal to use and sell?
