Lets say I made a mistake in an obligatory prayer and were unaware or I had a doubt but disregarded it, is my prayer then going to be accepted or on the Day of Judgement will I be punished for having a prayer missed because technically it won't be valid? Also, the same rule for wudu if I made a mistake and ... will I be punished ?
If possible can you use Quran verses or hadith to support answers.
