Jibreel (alaihis salaam) coming to earth four times

Q: Is the story of Jibraeel (alaihis salaam) coming to earth 4 times true?

The first was for Ebrahim (alaihis salaam) when he was thrown into the fire.

The second was for Ismail (alaihis salaam) when the knife was placed on his neck.

The third was for Yusuf (alaihis salaam) when he was thrown into the well.

The fourth for Nabi (sallallahu alaihi wasallam) when his tooth was struck at the battle of Uhud. Is this story authentic and correct?

Telling one's wife "mujhe tumhare sath nahi rehna"

Q:

1. During an argument/fight, my wife said to me “mujhe tumhare sath nahi rehna” and I replied to her “mujhe bhi tumhare sath nahi rehna” so will it be a talaaq?

2. Is the word “mujhe tumhare sath nahi rehna” a word of talaaq?

3. Is saying to one’s wife “mujhe tumhare sath rishta nahi rakhna” will lead to talaaq. Is this sentence a word of talaaq?

Will talaaq take place if husband says "That's it"?

Q: I have this issue which happened last year, but it has been playing in my head ever since.

Whilst my wife was fighting with me and moaning about my mum and sisters, she was upstairs saying this and I was on the sofa downstairs. She kept going on about them and in my head thoughts came up to say ‘that’s it I can’t take this anymore I want a divorce’. This was in my thoughts and was not spoken out loud at this point. Then straight after this thought she stopped for a few seconds and then started saying stuff again and I then immediately got up and said ‘that’s it’ so quick without thinking but I don’t know if my intention was divorce or to say I am fed up with you moaning.

After a little 5 second break of me saying ‘that’s it’ I said I’m going to speak to my mum and dad, and they can speak to your mum and dad’ I may have been referring to divorce or about her moaning I really can’t remember.

Since then my head has been playing this scenario back to back trying to find out what my real intention was when I said the words above, I really can’t remember now as it happened last year.

I would say 90-95 percent may have been with intention of divorce but there is a doubt of 5 to 10 percent that I did not and was just fed up of her moaning all the time as it happened so quick. I also get waswasa where the words divorce are most of the time just in my head even when I try to ignore them and I could be having a normal conversation with my wife and the words would just been in my head whilst speaking during a normal conversation as well as fighting.

Please can you confirm the status of my marriage and if I am needed to do my nikah again and if I do. Do I give dowry again and how many witnesses do I need?

Studying comparative religion

Q: I am a Muslim Alhamdu;illah and I try to learn about Islam whenever possible and read the translation of the Holy Quran and believe in the Oneness of Allah Almighty, the prophecy of Hazrat Muhammad (sallallahu alaihi wasallam) being the last prophet of Allah Almighty.

I also have a belief that the Torah, Injeel and Zaboor are also the Holy Books which are testified by Allah Almighty. But I also believe that the Torah and Bible have been altered or fabricated by Jews or Christians.

Kindly guide me whether I can read the translations of the Bible or Torah to know about the details about the history of various Prophets (alaihimus salaam) and to have a comparison where Jews or Christians fabricated the Holy Books.

I want to study these Holy Books for history knowledge as well as for comparison while having a strong belief that the Holy Quran is the ultimate truth.
