Making the intention of Zuhr salaah when performing Asr salaah

Q:

1. I was praying behind the imaam. The imaam was praying asar salaah and I made intention of zohar salaah and I know that it was asar after the prayer. Is my prayer valid or do I have to redo my asar salah?

2. If I am praying alone or with the imam and it is asar time and I make intention of zohar forgetfully and after one rakaah I realize that it is asar, do I have to redo my prayer?

3. What if it was just at the begninng i.e I am doing recitation before fatiha and I realize that it is asar, do I have to redo my niyyah and start over?

Telling one's wife, "get out, get lost" etc.

Q:

1. Sometimes my wife comes to me and asks me about doing something. I reply to her "jo dil chahe karo", Is say it sometimes to show my anger, and sometimes just to tell her that she can do it or not. I never used the word "free" or "azad" or "farigh" and never intended divorce. Additionally, we both originate from same city and same neighborhoods, and we both don't understand "jo dil chahe karo" is not considered exclusive term for divorce.

2. During a fight I used the words such as dafa hojao "get lost", "buy ticket and leave", "get out" etc. and never once intended divorce.

Receiving a prize in a lucky draw from a bank

Q: I am living in United Arab Emirates (Abu Dhabi). Here, there is a scheme available in the Banks by the name of "National Bond". In this scheme, I have to buy some bond with the minimum of 5000 Dirhams. This 5000 Dirhams will always be with the bank until I withdraw it. Every month the bank will have a lucky draw and the winning price will be 100 000 Dirhams or 1 Kg of gold, etc. If I withdraw the 5000 Dirhams then I no longer qualify to participate in the lucky draw. Is this halaal or haraam in Islam?

Women visiting the mubaarak grave of Rasulullah (sallallahu alaihi wasallam)

Q: What response do I give to this sister. She sent me the following:

I have a question regarding visiting Rawdah (Blessed grave of Nabi [sallallahu alaihi wasallam]) as the workers here have created a doubt in my mind. Is it possible to get the answer?

A staff member was explaining that when we (ladies) visit the Rawdah, our intention should purely be ibaadah in Riyadh ul jannah and not to visit Rasulullah (sallallahu alaihi wasallam) as he disliked ladies visiting graveyards. Then she quoted an ayah/hadeeth in Arabic and stated that He never said ladies shouldn’t visit graves except for mine. So she mentioned that we should all rectify our intentions before going inside.

I know there is a difference in opinions and people in Saudi might be from a different school of thought, but for us being Hanafi what is the ruling?
