Assalan alaikum! My knowledge in religion wasn‘t good. When kafir helped me I answered him May Allah reward you. Is it apostasy? I meant that Allah gave them sawab, sometimes I meant that Allah gave them good in this life.
2. when I saw God fearing christian I was glad that they were trying to be best in religion in the meaning I liked that they fear God because a lot of people atheists. Because I think atheist was worse. Also I liked that they were very diligent in religion but I didn‘t mean I like their kufra I like their commitment to God. Is it also apostasy?
Wa’alaykum as Salam wa rahmatullahi wa barakatuhu,
In both instances you will not become a disbeliever.
