Making a bequest for a non-heir

Q: My mother passed away 35 years ago my father never remarried. I am his only son and have two elder sisters. My father passed away recently leaving a will which stated that all his household content is to be given to my elder sisters child which is his grandchild. This child also has the first option to buy his house at market price. He has 15 other grandchildren. This has split the family as a grandchild may not inherit from him. The money from the sale of his house is to be divided equally between his three children. Can you please give advise as to the right way things should be done.

Tawbah

Q: If a female who is menstruating makes a mistake and cannot pray the prayer of repentance so she repents in her heart by asking for forgiveness and saying sorry and at the end says ameen, does it count or do you have to read /say something a surah or something in the beginning as well?

Taking a false oath

Q: I have made a mistake and I don't know what to do. This morning my mom told me to eat my vitamins but I didn't want to because I have heard that those brand of pills might have something that might be derived from animal products. So I wanted to make sure before I took anymore but I have OCD and I doubt everything. So I didn't tell anyone. Today after school she told me that I didn't take them and she is always worried about my health and stuff so I lied and said I did know it was bad I just knew she would tell me to take some right away if I didn't and by accident I said I swear to god I did. I regretted it as soon as it came out. I didn't mean to and now I am very worried. I didn't want to say that it just came out. I feel so sorry but I don't know what to do. I am going to try to never say anything like that ever again and I will try to not lie about taking pills anymore. I am menstruating right now and so I can't do a prayer of repentance. I don't know what to do? I feel very bad about what I said. I will try my very hardest to never say it when I am lying ever again. What do I do. Please help. I am very worried.

Being involved in a haraam relationship

Q: I am a 37 year old woman and have been married for 18 years. I am not happy in my marriage and due to this I have pushed away my husband. We both live in one house like complete strangers. This has led me to have a relationship out of my marriage! I know this is gunaah but I have been with this man who I love dearly. I am stuck and feel very guilty for all that's happened but I can't leave this man. I feel I will die without him. This man has now married in my family with a close relative and says he will never leave me, but I know as well as you this is impossible. I feel stuck, hurt and upset. Please guide me. What should I do as I do not have any will power to walk away. I feel lost.

Inheritance

Q: My father passed away leaving behind some assets (land & money). My late father has 5 sons and 4 daughters and my mum. My questions are:

1: Who has more right over the assets, my mum, sons or daughters or a combination of those?

2: Who's name should the assets be transferred to?

3: How do we distribute the shares (estimated value of £100,000)

4: Would it be right if my mum decides without the consent of the sons to sell some land and spend as she wills?

5: If she was to sell and spend should that about be deducted from her share from the total asset?

6: How do you calculate the shares. Above figure is only a estimate, can be more or less?

7: One of the assets is a house. If 2 sons spent £2000 on painting the house whereby it may or may not increase the value of the house (the other 3 sons were not in a position to contribute at the time) does this give the 2 sons more ownership over the house then the remaining sons? Does that also affect the shares if the house was sold?

8: Would a solution to question 7 be that to sell the house at the value it has. Distribute the shares accordingly. Then the remaining 3 sons that couldn't contribute at the time pay their share to the other 2 brothers which would've been £400 that was spent on painting at the time?

Surah Maaidah verse 143

Q: When his Lord manifested His illumination to the mountain, he sent it crashing down to pieces, and Moosa fell unconscious (Quran 7: 143). One of our fundamental beliefs as Sunni Muslims is that there is nothing like Allah,  (لَيْسَ كَمِثْلِهِ شَيْءٌ ). So with that in mind, does the illumination/light of Allah referred to in this ayat actually refer to a veil of illumination/light? Please clarify this.
