Wife requesting separate living quarters

Q: I am married and have 3 kids. I am the eldest in my family. My mother, one married and one unmarried brother lives with me in my house becasue my father passed away 9 years ago and my family moved in with me after that. Now both brothers are working as well. The relationship between my wife and mother is not good and it is going from bad to worse even after some reconsiliation and guiding. Both of them regard want their rights in Islam.

My wife is now demanding a separate accomodation and requesting me to ask my family to get a separate house because the house in which we are living is owned by her. I humbly request my brothers and mother but they all get annoyed and my mother gets very rude and very disappointed. I request them all to get accomodation near my house as they can afford it or I will support them in any way possible. I told my mother that I still love her and she is my first love. I respect her and I made this decision because of  my love for her. Did I do the right thing or did I disrespect my mother? 

Drawing Arabic calligraphy

Q: I'd like to enquire about the permissibility of the following

1. Drawing Arabic calligraphy for hanging on one's wall as remembrance of Allah Ta'ala

2. Drawing Arabic calligraphy as a means of remembrance of Allah Ta'ala for others, through which one may derive an income from its sale.

The Arabic calligraphy is legible to one who can recite basic Arabic, and does NOT form animate pictures, nor does it have animate objects in it. Examples are, names of Allah Ta'ala, Quraanic ayaat, zikr (SubhanAllah, Alhamdulilah, etc.). If permissible, then please advise if there are any further details that I should be precautious about.

Getting sin for inviting people towards wrong

Q: If a Muslim has a group of Muslim friends. The man knows zina is haram. His friends dont know zina is haram. The man invites them to commit zina. They all go and commit zina. The man doesn't commit zina.

1. Will the man be getting their sin of zina or he wont be getting their sin of zina since the friends were unaware of the act being haram?

2. Is the man guilty of kufr because his friends did not know zina is haram and they thought it was halal and committed it. (Thinking a haram act as halal and doing it is kufr).

Zakaat on gifted jewellery

Q: Many years ago, my maternal grandmother had kept an amount of gold jewellery in order to give it to me in my marriage. Later, my mother took it from her, telling her that she would keep it safely until the marriage. So the jewellery is with my mother.

Now, since I am unmarried, I have not received it yet. My question is: Who is responsible for the payment of zakah for that particular gold jewellery?

Father taking a loan from his children for his business

Q: Kindly advise with regard to the following:

Four siblings had sold a jointly owned asset and had given their father the money which was to have been invested by him in a property. However this did not happen for whatever reason and the money remained in the father's business. Over time it was even forgotten that this money has not been invested and has merely been left in the business. The father too had completely forgotten about this money that it is lying in the business. 14 years later one of the siblings passed away. It is now two years since his demise. He has a minor child and two adult children.

Nevertheless it has now been remembered that this money is lying in the business and was not invested. The deceased sibling's share (R95000) has not yet been distributed to his heirs. The father is in the process of returning the money to all the siblings and to the estate of the deceased.

It has been established that none of the the siblings, including the deceased, had included this amount in calculating their zakaat liability. The questions are:

1. Do the living siblings have to pay zakaat on this wealth that has now been returned to them? If yes, how will this be calculated?

2. Will zakaat be payable on the share of the deceased (R95 000) for the period until his demise? If yes, who is responsible to discharge this?

3. Are the heirs of the deceased liable for zakaat upon their respective shares for the past 2 years?
