Those situations where Talaaq does not take place

Does divorce take place by the husband joking that he did not accept at the time of nikaah?

Q:

1. At the time of nikaah the husband said qubool and the witnesses heard it. Few years later, the wife asked her husband if he said qubool in the nikaah? The husband said "no". He said “no” jokingly and had no intention of divorce. Is there any problem?

2. If a divorce thought comes in the mind when touching a kinaya word of divorce, is there any problem? The husband did not utter the word, he just touched the word with his finger. 

Wife not sure if husband divorced her

Q: If a husband denies and is ready to give oath about not divorcing his wife but the wife thinks that he has divorced her over the phone. She is confused as her husband is giving an oath and she too was very angry when she asked for divorce so she isn’t sure whether he said it or maybe she heard it wrong. Who should be believed, the husband or the wife?

Husband attributing divorce to a future date

Q: Me and my husband had an argument and then I came to my parents house. I was pregnant at that time. My husband, just to threaten me so that I would come back home sent me a message saying "divorce Septmeber, 2017". He wanted to tell me that he will give me a divorce in September but he did this just to make me upset and did not intend as such. The very next month, in April, he came to me and we had a relation and apologized for what he did. He said that he just did it to threaten me so that I would come back. We want to know if it will be counted as divorce? 

Husband telling his wife "I want to divorce you"

Q: On 21st November 2018 we had a baby and on 29th November 2018 my husband said to me "I want to divorce you" three times. He had brought two witnesses with him. I was still impure from my delivery that time. Since then I am staying with my family and have been trying to reconcile with him. Now my husband is willing to reconcile but we dont know if it is possible. My husband says that even though he said "I want to divorce you" he had the intention of divorce. Can you please tell us if the divorce happened and how can we reconcile? 

Husband retracting from his confession of divorce

Q: During a quarrel with one's wife, the husband said to his wife "We have no relationship" without the intention of divorce.

When the wife asked the husband what was his intention, the husband got angry and said that he had the intention of divorce but after some time later he said that he had no intention of divorce. He really said it without the intention of divorce.

My question is, the husband had no intention of divorce but he just said that he had the intention of divorce (he spoke a lie) so will divorce take place?
