Husband leaving his wife alone with his brother

Q: My qustion is about my brother inlaw: He is 23 years old and I am 27. My husband works 7 days a week and he comes home late night. On Sundays and in the mornings and evenings I am alone with my brother inlaw. We live in uk and have just one bedroom and living room where he sleeps. My problem is I am really not happy about sharing my life with him. I don't trust him and life is hard since I have to cover self while cooking, going to bathroom, etc. I have spoke to my husband about it but he doesn't care. My brother inlaw lives here illegally and he has got the option to live somewhere else as well by his own, the only difference will be that has to pay his own rent. My husband don't want that because he is after saving as much as money as he can. I feel angry and especially that I can't have my privacy and his brother finds out everything I won't like to tell him and so my in-laws through him. In last time me and my husband are having lots of arguments and he even gave me one talaq for no reason  because we had an argument on his brother. Now my question is: is it wrong in Islam if I don't want to live with my brother in-law? My husband spends more time with him then with me. I feel upset. Is not my rights bigger then his brother? Shouldnt he be more with me? I love my husband but I feel so much neglected that I'll say I'll leave him. My other questions is: What if I complain to the home office anonymously if it's allowed in Islam. I feel wrong to do so since we paid 7000£ for his brother to get here and I thought it'll be good so my husband will have some support, but I didn't know he'll live with us.

Witness not hearing the nikaah

Q: I performed nikaah few days back but after some days the witness told my husband that he didn't listen to the nikaah ceremony properly and didn't listen when I said "yes" for the nikaah. He said that during nikaah his mind was deviated from the ceremony and in short he didn't listen to our nikaah and my acceptance. He then advised my husband that he should perform nikaah with me again. So I just want to say that was that nikaah valid or not because the witness denied that he listened to the nikaah.

Bleeding after nifaas

Q: I gave birth on 15 May 2016. I had a ghusal on the expiry of nifaas which was the 24th June 2016. However I still continued to bleed till now. In a week I will stop bleeding for 2/3 days then it would resume. In this scenario do I count my Haidh and if so how do I go about doing it?

Partnership

Q: I purchased a 33.3% share in a property (empty land). I paid the asking price. I decided to return my share to the Muslim brother I purchased from because I did not have additional funds to contribute towards the building. I have not as yet received any refund for my share that I returned. In the process, the Muslim brother has sold my share to somebody else and as payment accepted 2 apartments. These apartments were offered to me as payment. I refused. In the process additional building has started taking place on the property. My question is, do I have a right to take back my share considering that I have as yet not received payment for it? and 1) If no, I understand 2) If yes, at what price must I contribute towards the new building that has been happening. I know I have to contribute a third, but is the Muslim brother allowed to put a mark up on the building or not, considering that I am an equal third partner. (3 partners, muslim brother, his brother and myself.)

Imaam taking a salary

Q:

1. If an imam has no duties except leading farad prayer, is his salary a price/ reward for his salaah? Is it not worshipping for money? Is it halaal to charge for what has been obligated by Allah Ta'ala?

2. If you employ a Hafiz to lead taraweh prayer in Ramadan, is his worship (for money) permissible and is the worship of his followers, behind him, acceptable before Allah Ta'ala?

3. When children are taught Quran by a paid tutor, is the teacher allowed to accept this material reward and still be 'khyrokum munn ta allaml quraana wa allama hoo'?

4. If it is not permissible to trade your (farad or sunnah) Ibadat for money/ receive salary, how should Imams of masjids and tutors run their household and kitchen?
