Maintaining family ties

Q: What is the meaning of the verse:“O Mankind! Fear your Lord, who created you from one soul and created from it its mate and dispersed from both of them many men and women. And fear Allah, through whom you ask one another, and the wombs. Indeed Allah is ever, over you, an Observer.”[Quran 4:1]

And “But those who break the covenant of Allah after contracting it and sever that which Allah has ordered to be joined and spread corruption on earth – for them is the curse, and they will have the worst abode.”[Quran 13: 25]

Which kinship is Allah Ta'ala talking about? Is it only my parents, grandparents, uncles, aunts, siblings and first cousins?

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.
