Q: 3 days ago my husband gave me a divorce in one message by saying that as per your wish, talaq talaq talaq... And you are free from my side. But I have my periods in these days. Someone told me that when a wife is not in taharat, talaq cannot tak eplace and she gave me a refrence of Hazrat Umar (radhiyallahu anhu), that once he gave talaq to his wife in anger, and when he asked Hazrat Muhammad (sallallahu alaihi wasallam), he said wait for her to become pure then you can give her a divorce if you want to... kindly guide me.

Thoughts of shirk

Q: Because of some thoughts that came to my mind, I thought talking to a friend is shirk so I planned to stop talking. For that I called that person and informed that person that I won't be talking to that person anymore and that is tha last time I was going to talk. We talked for while, when I was talking I felt like I was committing shirk by talking to that person then I thought that I will commit shirk this time and ask for forgiveness from Allah and stop talking to that person. After that incident I got to know that it was not shirk to talk to that person so they told me to talk to that person now am talking to that person but still am confused that if I was ready to commit shirk because of that person did that mean I comit shirk and I gave more priority to that person than Allah because in that time I thought to commit shirk one time and ask for forgiveness so after I think like that is it shirk to talk to that person now ??? Is there is any way to make it normal ... I asked forgiveness from Allah if I have committed any shirk and now am talking to that person as normal because that person is not more important than Allah but still .. is there is any shirk in talking to that person now ???? Or did I commit any shirk by thinking like that while talking that guy?

Purchasing a house and giving it out on rent

Q:

1. Some one is on rent and they are still on rent and he has sold his house for 27 lacs and he has not still enough money to purchase a house in which all family members be settled. And now he is trying to purchase a house in a sense so that he can fulfil his current financial problems (for giving current rent in which they are still living), through rent income. It is permissible in Islam to purchase a house and allow it on rent , the income of this house is use for the rent of a house in which someone is rented.

2. It is permissible in Islam to invest the payment of sold house in a National savings centre in that sense to gain the fixed amount for a month (e.g. 9000) so some one can fulfil his financial problems (for giving current rent in which they are still living).
