Selling artificial rings

Q: I read in Behashti Zewar that it is not permissible for women to wear artificial rings.

1. Since I was unaware of this ruling, I already have many such rings that I used to wear. What should be done with those rings?

2. I have given rings as gifts to many women in the past and my jewellery business gave me profit from selling artificial rings. Will I be sinful for this? What should I do now?

Telling one's wife "I will divorce you"

Q: My spouse and I had a severe argument and in anger and anguish without realizing I said to her I will divorce you. When I came back to my senses I realized what mistake I made since it wasn't my intention but she abused my mother and I completely lost it.

Last year we had few fights and I had said this twice but she has always stopped me but I am not sure if divorce is done or not. If it has, is there a way out of this since I wasn't in my senses.

Doubts regarding a leather belt

Q: I wear a trousers belt, it's leather. I don't know what kind of animal skin was used to make this leather belt. I heard that if you wear leather made with pig skin and if you pray salah with it, it wouldn't be accepted, it's nearly impossible to tell if the leather is pig skin or not because where you buy it, it doesn't says. Would my salah be valid? 

Provident fund from the government

Q: I live in Pakistan and my father is a govt servent. He is about to retire and at retirement the govt gives alot of money as provident fund. This money is actually a combination of 3 things.

1. It cuts from monthly salary for over 25 years.
2. Each month govt adds some amount to this monthly.
3. Bank adds up interest and that I also added to the amount

At retirenment all these amounts add up and given to the employee. So is it halal to do hajj with this money?
