Q: My friend and her husband are in their 60s. Children all married. They had a big house both of them owned because both worked hard to buy that house and they lived in this house for a long time Alhamdulillah. Now her husband retired and he sold the house and they now travel or live with their children one by one. He kept all that money in a secret account. She did not get anything. She wants to know can she take little by little from him without telling him? If she ask he won't allow her. But if she takes it without telling him he will never find out. Is this ok to take her share little by little without telling him. Please respond.

Q: Are we Muslims allowed to attend marriages of non-muslims?

Q: If a man's wife becomes ill and sickly and therefore she will be  unable to satisfy his sexual desires, would it be ethical for a man to get another wife or will it be unethical. The man will still dedicate his time to take care of her needs. He will not desert her. In terms of shariah, does it become compulsory for the man to get another wife if he still has a lot sexual desire in him? If he does not get another wife out of kindness and service to his first will, will this be considered as being foolish while he still has sexual desire and cannot satisfy himself with her?

Q: Is it permissible for a boy who wishes to get married to see the girl? Nowadays when the boy goes to see a girl, then they both sit and speak?
Is this permissible if done in the presence of the girls parents? I am not speaking about after the proposal is accepted by the girls party for boy and
girl to meet and speak. I know this is not permissible.

Q: Please write for me the authentic sunnats of the wedding night.

Q: My wife and I have not had a sexual relations for the past 13 months. Our reasons are many..

1. We could not do the act properly due to her weight or at least I felt so.
2. I met with a major accident in early last year and was disturbed for sometime, however there was no physical problem with me.
3. I was travelling on work and we were living separately off and on for duration of upto a month or a little more.

I was listening to the tarjuma of the Quran and came to know about the verse regarding ila. I did not know about this verse earlier and the time limit of 4 months mentioned in this verse. Though I have never told her that I will not have physical relations with her with the intention of ila, however I might have told her the same "I don't want to do it until you lose weight" when we would have had arguments. I did not know about ila, else I would have never uttered such words even in arguments. We have had our differences but we are trying to sort them out. In view of the above circumstances is our talaq confirmed as it has passed the 4 month period of ila? I do not want to separate and I have not told her regarding this yet. I am very disturbed.
