Unfortunately, I was wasting time playing a game on my phone. Convinced I would reach a particular score in the game I was playing, I thought to myself if I don’t reach that score, I have become kafir. When I didn’t reach the score in mind, I became worried and have since done tauba for such a thought. Similarly, as I was getting to a crucial part of one game, I thought, please Allah, don’t make me bloody lose. I have replaced the f-word, the word bloody in this question because I am too ashamed to write it. I am burning inside and can’t know focus because of what I deliberately thought. I know thoughts are not kufr but could you please confirm this is not kufr?
