Shias,Statements and Jannah

Aslaamualaiqum
I pray you are well and in the best of spirits. We read one of your fatwas about kaafirs and Jannah and we have a few questions linked to this topic.

1)If a Muslim woman’s husband tells her that her shia friend will go to hell fire because shias are not Muslims. And the Muslim woman is shocked to hear this and verbally says regarding this matter: ‘she will go to jannah because she is a Muslim, doesn’t matter if she is a Shia. Shia people are Muslims, she is a muslim and she will go Jannah.’
Does this thinking, being shocked as explained above ,understanding, any of the above and verbal sayings as above (maybe due to lack of knowledge/understanding) make the Muslim woman a kafir?

2)Or if the Muslim wife is shocked to hear that shia people are classified as non Muslims and finds it hard to believe/understand that shia people will not go to Jannah. As she thought and understood that shias were Muslims and will go Jannah. Does this thinking, understanding, finding it hard to believe, being shocked or any of the above make the muslim wife a kaafir?

3)Or if the Muslim wife maybe due to lack of knowledge/understanding is shocked after being told that only Muslims will enter jannah and finds it hard to believe about non Muslims not going to Jannah. And Verbally says, ‘that’s not correct/right, Christians/non mulsim people will also go Jannah if they are/do good.’ Does this thinking, understanding, being shocked as explained above and verbal sayings or any of the above make the Muslim woman a kaafir?

The Muslim woman/wife in the above questions do not have any intention to disagree with the rulings of Islam.

Jazakallah
