Wa Alaykum Assalam and thank you for your question.

 

Those ahadith are simply saying that the three categories of people mentioned in each hadith, their prayers will not be accepted unless they stop what they are doing:

 

1.  A man who leads people in prayers when they dislike it should stop leading them in prayers.

 

2. The woman who made her husband angry should make sure that her husband is pleased with her.

 

3. The two brothers who severed contact with each other should reconcile and forgive each other.

 

The second hadith adds another category, which is a runaway slave until he returns. This is no longer applicable in our time.

 

I hope this helps answer your question.

 

Salam and please keep in touch.
