A PDF cannot correct your mistakes. Join an online Tajweed class (many Uzbek groups use Zoom or Skype). Show your screen share with the PDF, and let the teacher correct your pronunciation of the throat letters ( ع , ح ).
Remember: Tajweed is not just about rules; it is about giving the Quran its right. Every letter pronounced correctly is a blessing. Every color-code followed is a step closer to reciting the way it was revealed to Prophet Muhammad (peace be upon him). tajvidli quron kitob pdf skachat
