Leaving a mixed engagement function

Q: My sister had an engagement function recently. I was under the impression that it will be completely separate. I had spoken to my sisters and mother before and they said there will be a purdah in the center and my sister will sit on the ladies side and her fiancè will sit on the mens side.

On the day of the engagement when I went to the hall there was incomplete seperation between males and females - the partition covered only 2/3rds of the hall. Men seated at the front were in full view of women seated at the front. There was a table for both the bride to be (my sister) and the groom to be seated together on the ladies side. There was only 1 tea table was set for both men and ladies.

I tried to speak to my sisters who were there that it wasnt what I had expected but they kept brushing me off. I was then furious and I phoned my mother and told her that that was not what I had expected and that I will not attend the function. I might had spoken to her abit harshly. She spoke to my sisters and they decided to put a second pardah at the back but it was still not good enough as the seperation was incomplete.

This was a few hours before the function and we went back home to get dressed for the engagement. My cousin and brother in law started arguing with me that its not serious and that its my sisters function and im being too harsh and strict. When I spoke to my wife she was half minded about going but we decided to go to keep family ties. My wife is in niqaab and after the function started, she told me that she is not happy with the incomplete seperation, 1 tea table and that the bride and groom to be seated next to each other on the ladies side. My wife ask me to drop her off at home which I did and I was half minded about going back, I did but I did not go into the hall to eat but stayed outside and helped them to dish out etc.

My family is very upset and disappointed that my wife left the function without saying anything and that I did not sit and partake of the food which was served. I felt it was wrong for me to be part of such a gathering as I wear kurta, turban and have a full beard. They feel that we are breaking family ties when Allah commands us to obey our parents even if they are non Muslims. I am the only son by the way. They are also upset about the way I spoke to my Mother. They are saying that people were asking them where is my wife and why am I not in the hall. Someone else had also said we visit shopping malls which are mixed and make tawaaf which is mixed therefore howcome we "made such a fuss" at the engagement which was not completely seperate. They also say that we do other things that are not correct so why are we so strict with this.

Kindly advise whether what my wife and I did was correct, how to unite the family and the way forward regarding such events in future. Any other advice will also be appreciated

Taking out life insurance to save tax

Q: Is it permissible to buy a life insurance policy, not so that my heirs can benefit from it; but merely to cover inheritance tax/estate duty that is so exorbitant that due to not having so much cash funds in the estate, essential assets such as the house in which the heirs live in has to be sometimes sold just to pay the estate duty? The heirs will be instructed that after paying the duty, the surplus must be given away in charity without intention of reward.

Working as a chartered accountant

Q: I have a doubt... sometimes chartered accountants have to record the interest (riba)of a company. The chartered accountant is not involved in that dealing nor he is present in that meeting nor has he witnissed it, but he has to record it as he has to manage other accounts of the company also. So will he also be responsible? Is that also haraam?

Eating from a Shia

Q: I work in an office as an accountant and there is a girl in the office who is a Shia. Sometimes she brings something from her house and gives all the staff to eat and she also eats herself. Some occassions she gives money to something to bring something for her to eat for herself and she also offers us (the staff) to eat.

So my question is, can a Muslim (Deobandi or Barailwi) eat when any Shia gives anything to eat whether cooked or brought from the shop (like chips, biscuits) etc. Is is permissible. I personally do not eat but other Muslims eat and she feels bad and says that I will not eat from Shias. Is it correct what I am doing?

Fulfilling the rights of people

Q: Despite being very careful and conscious with fellow humans that I don’t hurt anybody in anyway but still I feel guilt and look for instances in my past where I might have hurt somebody with my hand or tongue but there are always shortcomings intentional or unintentional.

My question is what if we did wrong to somebody in the past and don’t recall who it was or if it was minor or major. For example, abusing out of anger if someone hit your car what will be the punishment or how to repent to Allah Ta'ala as I read that Allah Ta'ala will not forgive such and such violations of huqooqul ibaad. These thoughts are disturbing me and it's becoming hard for me to be a productive Muslim because of these distressing thoughts that I will burn in hell whatever good I do.

Even though there were many examples where people did wrong to me but I didn't take any action rather let them go. I must have done bad deeds too but not too sure when and where. I feel distressed and hopeless trying to be so perfect where people don’t even bother much and they are still happier.

Moreover I start to fear death at times and what will happen after that etc and my mood is depressed a lot of times please suggest me what should I recite and hope for the mercy of Allah.
