Making qadha for Salaah missed intentionally

Q: If a person misses zuhur salaah intentionally and it is time for asr. So can he make up zuhur prayer after asr or before asr?.I asked this to scholar and read on islamqa.com which says it is a difference of opinion. The most sound opinion is it is not permissible to make up as qazaa salaah. I see a lot of people in India making up missed prayer after the time has passed but I tell them it is not permissible and they argue. Please explain.

The harms of women attending university

Q: I am 19 years old and I got nikaah with a family friend. It was arranged.

So nothings really changed for me, I still live with my family and he lives with his but we're married islamically. However, I regret my decision. We don't really click and I am not happy with him. I regret my decision a lot. I feel like I'm too young and I barely know myself. I want to find myself and just be a normal 19 year old girl going to university. I brought up divorce to my parents and they aren't taking it well at all. They are threatening me and abusing me for even thinking about disgracing them like that. I don't know what to do. should I go through with it and be unhappy for the reason of my life? or should I take a stand and risk getting disowned?
