Keeping the name Arya

Q: I am blessed with a baby girl.

1. I would like to know what are the considerations to be kept in mind before naming the child according to shariyah.

2. Is a Arabic name a must? Is a quranic name a must?

3. Does date and time of birth pay any part in selecting a child's name? What effects does a name have on the child and his personality?

4. The name my wife and I like is ARYA which is non arabic and non Quranic. It means Nobel and lioness. Has its origin in Hebrew, Sanskrit and Italian. Have not heard any Muslim child in our part of world with this name.

Telling wife that we are separated for 40 days

Q: I got married last year and it was a love marriage. I moved abroad and my wife is still back in my homeland. We fight alot. Before and even after marriage, we beat each other, obviously I am the husband so I beat her harder.

Now, every time we fight, it ends with her asking for talaq, or I tell her to leave me, or I tell her everything ends etc. But recently in messages, we fought again, and as usual she asked me for talaq and this time I said to her that we are separated for 40 days. Then I blocked her from every social media that we keep contact on. I haven't called her or said any words of talaq. 

Child sitting in a tub of water after passing urine or stool

Q: My little brother usually plays in a small tub of water. He was wearing swimming shorts and went to urinate, he didn’t do istinja (he usually doesn’t do it after urination and defecation). Afterwards he came back and sat in the same tub of water. Does the water become impure? I don’t think the smell color and taste of water changed after that.
