as-Salaamu 'alaykum Mufti:
When I got home from work after a long commute, my wife started lecturing me about helping around the house and mentioned that the Prophet (pbuh) would do this. Unfortunately, this was done after a disagreement about something insignificant.
In short, I told her that she shouldn't mention religious matters when the other party is angry as they might respond by saying something they ordinarily wouldn't say that might be a statement of kufr (disbelief). I then say something along the lines of "get out of here with that nonsense," as I was angry. I wasn't referring to the Sunnah or the hadith she was referring to being "nonsense," but I was trying to let her know that bringing it up in the manner she did was inappropriate (as I was actually reading a book about the Prophet [pbuh] when this happened and she hadn't mentioned anything related to the deen/religion the whole time I was home from work).
To cut a long story short, I just want ensure I didn't inadvertently leave the fold of Islam by my poor choice of words (as I was frustrated and was just trying to convey that bringing that hadith up in the manner she did wasn't appropriate).
JazakAllah khayr Mufti!!!
Assalam u Alaikum Wa Rahmatullah
If you had no intention to disrespect the Holy Prophet Sallallahu Alaihe Wa Sallam or Deen then your statement does not constitute Kufr (disbelief). You should however make Istighfar and seek forgiveness from Allah regardless of the affect of the words.
And Allah knows best
