One thing I don’t understand when it comes to ignore do we really ignore everything what happen like even we 100% sure and it takes about 5 or more minutes like when I am 100% sure I don’t said Allahu Akber correctly and ignore it out of laziness and then thinking so its invalid and I need to repeat

I'm assuming you're talking about waswas, and that you suffer from OCD thoughts. Unlike everybody else, when you pray, you keep repeating your prayer or repeating your wudu; instead of making wudu for one or two minutes, you take 30 minutes. If you're asking if you really have to ignore it 100%, then yes. Really, 100% you have to ignore all of these thoughts.
