Those situations where Talaaq does not take place

Explaining the serious consequences of uttering the words of divorce to one's wife

Q: When I get angry I used to say divorce me to my husband. Then to explain he said "I divorce, I divorce, I divorce. If I say these 3 words it would dissolve our marriage so don't say that again and again especially over the phone when you can't predict the other person's mental state and this can destroy our marriage, so don't ask for it again'. 

So my question is, does divorce take place by saying this because he was just explaining, without any pause, that I shouldn't ask for it again and again.

Husband telling his wife "I am leaving you"

Q: My husband and I had an argument on WhatsApp. He messaged me and texted that I'm leaving u from today..I'm blocking u all and said I'm breaking over the relationships. At that same moment I left the car as I was traveling and I asked him u divorce me... u using these words. He said are u mad .. did I used divorce... 

He swears to Allah he didn't intended divorce by that... He just threatening me and he just mean I will leave you but didn't leave. His sister saying she ask mufti and mufti said no divorce occur. What could I do, should I believe them?

Does talaaq automatically take place if the spouses did not consummate the marriage within 4 months?

Q: One of my friends married 6 month ago. But she and her husband still not had intercourse between them. She doesn't know anything about it. Her husband also not trying to do anything. What can we do for her? How to take his feelings out? I heard if a husband and wife don't have intercourse upto 4 months, automatically it will be talaq. Is it true?
