@@omarhandmade thank you for reply, I didn't know that but why do you need to do that? What do you use instead of qaf also why do you need to use two hamza or is there any difference between them?
@cokdillihayat-multilinguallife the reason is simply people found hamza easier than qaf. I understand that you may not agree if you learned only the qaf probounceation as in Quraan. But in fact in most arabic dialects ق is not pronounced as in Quran, for example in gulf it is pronounced as g in game .
