My pronunciation in prayer is terrible. I'm aware that this is an important issue, one that can even invalidate prayer which is incredibly worrying for me. Nevertheless I can't quite seem to get the hang of certain letters and words in Arabic. I've watched several videos on youtbe and had my brother help me and yet, though I know I have certainly improved, I am far from perfecting my pronunciation. What would you advise me to do. Are there any classes that I could attend or any particularly good videos that I may have missed, or maybe even books that could help? Any help would be really appreciated. Thanks for reading (and responding)
