We have to recite Quran and Arabic with correct pronounciation but whenever I see a video of who aren’t Arabs they have a weird pronounciation of Arabic and sometimes pronouce Arabic letters in the Farsi way , Why is this done? Can you please explain?
There is also a verse in Quran 73:4 ‘Or add to it, and recite the Quran as it ought to be recited.’ Can you explain?

You are required to recite the Quran as much as you can in proper Arabic. Anything you can’t perfect you will not be judged for it
